Notes: Many attempts have been made to use various types of photography for traffic studies. The problems most frequently encountered are the expense involved in obtaining the photography and the time consuming and, hence, expensive operation of collecting the required data from the photography. This paper discusses the problems associated with various types of photography and describes a study which has been carried out to evaluate the potential of 16 mm and 35 mm time lapse photography taken from a helicopter. The accuracy of two dimensional co-ordinate transformation systems for collecting the required data from the photography is also described. Finally, recommendations are made regarding the most suitable type of photography and the most convenient and accurate transformation system to use when it is required to analyse the traffic flow data at complex urban and suburban intersections.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméBeaucoup de tentatives ont déjàété faites pour étudier les problèmes de circulation par photographie: les difficultés sont le coût de la photographie, les délais d'obtention et le coût du dépouillement.

Notes: On 17th January, 1978, the Secretary of State for the Environment announced the establishment of a Committee, chaired by Sir David Serpell, with the following terms of reference: “Taking account of the views of users and other interested parties, in the context of national surveying and mapping needs, to consider and make recommendations about the longer term policies and activities of the Ordnance Survey and ways of financing them.” Interested organisations, among them The Photogrammetric Society, were invited to submit evidence to the Committee. The Society's submission is reproduced in full. The Secretary of State has asked the Committee to report, if possible, early in 1979.〈section xml:id="abs1-2"〉〈title type="main"〉SummaryAs has been stated the national survey, comprising as it does the horizontal and vertical control frameworks and the basic scales mapping based upon it, represents (assuming completion of the last named) a priceless national asset, but it is not “money in the bank”. It is an ephemeral and fragile asset which will have been frittered away unless it is constantly maintained, repaired and refurbished; even so it will not last forever. At one time or another the various components will all require replacement eventually. What must be avoided at all costs is a repetition of such culpable neglect that it all needs replacement at the same time. This summarises what is now, and must remain, the prime objective of the Ordnance Survey. Superimposed upon this are the needs to make the survey available, in various forms, to users; to produce small scale mapping; and to collect and disseminate various other forms of topographic data.〈section xml:id="abs1-3"〉〈title type="main"〉Résumé Le 17 Janvier 1978, le secrétaire d'Etat à l'environnement anonçait la création d'une commission, présidée par Sir David Serpell: les objectifs étant précisés de la manière suivante; “Tenant compte des besoins des utilisateurs et des autres parties intéressées aux activités cartographiques, proposer une orientation à long terme de la politique de l'établissement et revoir les modes de financement de l'Ordnance Survey.”Les organisations concernées, et parmi elles la Photogrammetric Society, étaient invitées à entrer en relation avec la commission: on reproduit ici in extenso la déposition de la Photogrammetric Society. Le secrétaire d'Etat a demandéà la commission de remettre son rapport début 1979 si possible.〈section xml:id="abs1-4"〉〈title type="main"〉Zusammenfassung Am 17.1.1978 kündigte der Staatssekretär für Umweltfragen die Gründung eines Komitees unter Vorsitz von Sir David Serpell an, dasfolgende Aufgabe erfüllen soll: “Analyse der Ansichten von Nutzern und anderen interessierten Gruppen bezüglich der nationalen Anforderungen an Vermessungswesen und Kartographie, um daraus Empfehlungen für die längerfristigen Aktivitäten des Ordnance Survey und die Möglichkeiten zur Finanzitrung abzuleiten.” Interessierte Organisationen, darunter die Photogrammetric Society, wurden eingeladen, die Tätigkeit des Komitees zu unterstützen. Für Anfang 1979 soll ein Bericht vorgelegt werden.

Notes: Stereophotography with a pair of 35 mm cameras and stroboscopic illumination was used to record, reconstruct and measure the trajectories of falling hailstones under extremely adverse natural conditions. Since it was not possible either to fix or to measure precisely the camera positions and orientations, a method was devised to obtain both the three dimensional hailstone co-ordinates and the camera positions and orientations by making use of the otherwise redundant information contained in the stereo-photography.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméOn a utilisé deux cameras de 35 mm et un éclairage stroboscopique pour enregistrer en vue de leurs restitutions les trajectoires de grêlons; ceci n'a pu être réalisé que dans des conditions difficiles.

Notes: Stimulated by promising overseas results with colour aerial photography and encouraged by its potential for solving local problems, the Forests Commission, Victoria, embarked on a series of trials with colour photography in 1965. Early results showed great promise and resulted in further work. This paper describes the methods and results of 70 mm and 35 mm trials concerned with the evaluation of various photographic films. An important aim of the study was to build up a working knowledge of the techniques of using aerial films other than conventional panchromatic black and white and to assess their value under Australian conditions.〈section xml:id="abs1-2"〉〈title type="main"〉Résumé Stimulés par les résultats obtenus outre-mer en matière de photo aérienne en couleur, et disposant d'un potentiel adéquat, le Forests Commission, Victoria a entrepris en 1965 une série d'essais, dès le départ très encourageants. On décrit ici les essais d'évaluation de différents types de film (70 mm et 35 mm); le but était de se familiariser avec la couleur et d'en étudier les conditions d'emploi sous les latitudes australiennes.〈section xml:id="abs1-3"〉〈title type="main"〉ZusammenfassungAngeregt durch erfolgversprechende Ergebnisse mit Farbluftbildern in Übersee und ermutigt durch die Möglichkeiten zur Lösung lokaler Probleme unternahm die Forstkommission in Viktoria (Australien) eine Reihe von Versuchen mit Farbaufnahmen im Jahre 1965.

Im Artikel werden die Verfahren und Ergebnisse von Versuchen mit 70 mm und 35 mm Aufnahmen zur Bewertung verschiedener photographischer Materialien beschrieben. Ein wichtiges Ziel der Untersuchung war das Erlangen von Kenntnissen über die Verfahren zur Verwendung nichtkonventioneller panchromatischer Schwarz-Weiss-Filme und deren Bewertung unter australischen Bedingungen.

Notes: A short review is given of photogrammetric methods in use for the test recording of petroglyphs and archaeological sites. Two simple field methods employed by archaeologists to record petroglyphs are also described in order to highlight the complexity of photogrammetric techniques and to query their validity.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméBrève revue de méthodes photogrammétriques en usage pour enregistrer pétroglyphes et sites archéologiques.

Notes: The CP1 plotter has been employed to produce, from low altitude aerial photography, a detailed map at a scale of 1: 1000 of a major landslide which occurred in an urban area of Hong Kong with extreme relief differences. Geomorphological features of the landslide could be interpreted easily from the aerial photographs and shown on the map which provided an accurate record of the disaster. Experiments with computer mapping of the landslide using a limited number of height points obtained by the CP1 plotter have also been carried out and the results indicated that useful data could be obtained rapidly to meet urgent needs for the preliminary stage of investigation and the planning of reconstruction works after the disaster.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméA partir d'une couverture aérienne à faible altitude, on a restitué au CP1 et à l'échelle du 1: 1000 une carte détaillée d'un important glissement de terrain survenu à Hong Kong et présentant d'extrêmes variations de relief. Les caractéristiques géomorphologiques du glissement aisément perçues sur les photos aériennes ont été reportées sur la carte. On a mené d'autre part des essais de cartographie numérique à partir de semis produits par le CP1, qui prouvent qu'on peut ainsi obtenir rapidement des données utiles aux enquêtes et mise sur pied des travaux de reconstruction.〈section xml:id="abs1-3"〉〈title type="main"〉ZusammenfassungDer CP1 Plotter wurde zur Herstellung einer detaillierten Karte im Massstab 1: 1000 nach Luftbildern aus geringer Flughöhe verwendet, um einen grösseren Erdrutsch mit extremen Höhenunterschieden im Stadtgebiet von Honkong zu kartieren. Die geomorphologischen Erscheinungen des Erdrutsches konnten leicht an Hand der Luftbilder interpretiert und auf der Karte dargestellt werden, die eine genaue Aufzeichnung der Katastrophe vermittelte. Es wurden auch Versuche mit einer rechnergesteuerten Kartierung des Erdrutsches mit Hilfe einer begrenzten Menge von Höhenpunkten, die mit dem CP1 Plotter gemessen wurden, durchgeführt. Die Ergebnisse besagten, dass dadurch wichtige Daten schnell ermittelt werden können, um dringende Anforderungen für eine vorläufige Einschätzung sowie die Planung des Wiederauf baus nach dem Unglück zu befriedigen.

Notes: A close range photogrammetric system, developed around a 35 mm Pentax camera fitted with a wide angle lens (f = 21 mm) and an early Zeiss wide angle multiplex, has proved useful for both instruction and research. Student exercises involve all phases of photogrammetry, from establishing ground control to plotting, and permit the integration of useful statistical routines for data analysis. Research applications have centred on the topographic mapping of microscale landforms at scales of 1: 1 to 1: 10 with accuracies of ± 1 mm to ± 5 mm.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméUn système mis au point pour la photogrammétrie à courte distance, et dont les éléments essentiels sont une chambre Pentax (f = 21 mm) et un Zeiss grand angle multiplex, a fait la preuve de son utilité tant pour l'instruction que pour la recherche.

Notes: A model of a multiple box girder bridge, constructed at a scale of 1: 12, was subjected to an ultimate load test. Deformations were measured photogrammetrically using the method of false parallax. Modifications to the method are described which were necessary to accommodate the three dimensional object and to allow for the fact that the camera stations were not constant from one load stage photograph to the next. An accuracy of ± 0·2 mm in the measured deformations was achieved.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméUn modèle de boîte de vitesse à l'échelle 1: 12 est soumis à des essais de rupture; on mesure les déformations par photogrammétrie, en utilisant la méthode de la “pseudo-parallaxe”; des modifications ont dûêtre apportées à la méthode pour tenir compte du volume de l'objet et de la variation des points de vue entre les différents états de charge.

Notes: Abstract. Brownfield sites often require a geochemical survey to assess the extent of contamination that is present as a result of previous industrial activities. These measurements are subsequently assessed to ascertain whether the site presents the possibility of causing significant harm to those who may use the site for specified purposes. The measurement process comprises both field sampling and chemical analysis, with sampling being of crucial importance, since previous studies have repeatedly shown that it is the sampling phase that generates the highest component of uncertainty. A variety of methods are currently available for sampling brownfield sites, such as different sampling patterns and the choice of depth and mass recovered. An investigator may also choose to employ more innovative sampling methods, such as in situ measurement strategies that can significantly reduce the overall time taken to complete the survey. The general aim of a sampling strategy is to take representative samples for chemical analysis, although this is rarely achieved due to the inherent heterogeneity of contaminants within any given site. Since it is practically impossible to sample an entire site, and thus achieve a truly representative sample, it is becoming increasingly understood that the uncertainty of the measurements should be estimated, to provide a more reliable interpretation of the survey. Various methods are currently available to estimate the measurement uncertainty that arises from both sampling and analysis, which vary in terms of complexity and cost. The level of uncertainty estimated during a site investigation should also be judged on its fitness-for-purpose (i.e. whether subsequent decisions based upon it are acceptable). The ‘optimized contaminated land investigation’ (OCLI) method is a new approach that can be used to balance the site-specific variables of any given investigation, such as the measurement costs against the level of uncertainty and costs that may arise from misclassification. This provides an objective and traceable judgement of whether the measurements are fit-for-purpose.

Notes: Abstract. Nuclear weapons' testing, mineral extraction industries and nuclear power generation are among the activities which have led to radioactively contaminated land. In the United Kingdom (UK), current activities such as the decommissioning of nuclear licensed sites and the sale of Ministry of Defence land require that the legislation, remediation and management of radioactively contaminated land be addressed. With an emphasis on the UK, this paper reviews potential management/remediation strategies for radioactively contaminated land, including consideration of the environmental mobility of potentially important radionuclides.

Notes: Abstract. Methods that can be used to determine the distribution of metal species in soil solution are critically reviewed and assessed. They are divided into two groups: those that can provide free ion activity, and those that measure labile species in solution. Ion selective electrodes have long been regarded as a promising technique, but there are practical problems in performing accurate measurements and only the Cu electrode has been used routinely. The Donnan membrane technique is capable of measuring the free ion activity of many metals, but adequate sensitivity can be a problem. Although resin competition methods are versatile, care must be exercised to avoid perturbing the solution excessively. Anodic stripping voltammetry (ASV) measures labile species, so the approximation involved in interpretation as simple inorganic species, from which free ion activities can be derived, should be recognized. Diffusive gradients in thin-films also measures labile species, but it is applicable to a much wider range of metals than ASV. It requires larger volumes of solution, but it can be used directly on the whole soil where it also measures the metal that can be rapidly supplied to solution. Other techniques such as permeable liquid membranes have yet to be used for measurements on soil solution. All of these methods have strength and weaknesses, and measure different aspects of speciation. Knowledge of the availability of the metals to biota is likely to be best advanced by the critical use of one or more of these speciation methods with a thorough understanding of exactly what is being measured.

Notes: Abstract. Effective use and recycling of manures together with occasional and judicious use of supplementary fertilizing materials forms the basis for management of phosphorus (P) and potassium (K) within organic farming systems. Replicated field trials were established at three sites across the UK to compare the supply of P and K to grass–clover swards cut for silage from a range of fertilizing materials, and to assess the usefulness of routine soil tests for P and K in organic farming systems. None of the fertilizing materials (farmyard manure, rock phosphate, Kali vinasse, volcanic tuff) significantly increased silage yields, nor was P offtake increased. However, farmyard manure and Kali vinasse proved effective sources of K to grass and clover in the short to medium term. Available P (measured as Olsen-P) showed no clear relationship with crop P offtake in these trials. In contrast, available K (measured by ammonium nitrate extraction) proved a useful measurement to predict K availability to crops and support K management decisions.

Notes: Abstract. Sodic and saline–sodic soils are characterized by the occurrence of sodium (Na+) at levels that result in poor physical properties and fertility problems, adversely affecting the growth and yield of most crops. These soils can be brought back to a highly productive state by providing a soluble source of calcium (Ca2+) to replace excess Na+ on the cation exchange complex. Many sodic and saline–sodic soils contain inherent or precipitated sources of Ca2+, typically calcite (CaCO3), at varying depths within the profile. Unlike other Ca2+ sources used in the amelioration of sodic and saline-sodic soils, calcite is not sufficiently soluble to effect the displacement of Na+ from the cation exchange complex. In recent years, phytoremediation has shown promise for the amelioration of calcareous sodic and saline–sodic soils. It also provides financial or other benefits to the farmer from the crops grown during the amelioration process. In contrast to phytoremediation of soils contaminated by heavy metals, phytoremediation of sodic and saline–sodic soils is achieved by the ability of plant roots to increase the dissolution rate of calcite, resulting in enhanced levels of Ca2+ in soil solution to replace Na+ from the cation exchange complex. Research has shown that this process is driven by the partial pressure of CO2 (PCO2) within the root zone, the generation of protons (H+) released by roots of certain plant species, and to a much smaller extent the enhanced Na+ uptake by plants and its subsequent removal from the field at harvest. Enhanced levels of PCO2 and H+ assist in increasing the dissolution rate of calcite. This results in the added benefit of improved physical properties within the root zone, enhancing the hydraulic conductivity and allowing the leaching of Na+ below the effective rooting depth. This review explores these driving forces and evaluates their relative contribution to the phytoremediation process. This will assist researchers and farm advisors in choosing appropriate crops and management practices to achieve maximum benefit during the amelioration process.

Notes: Abstract. Large nitrogen (N) inputs to outdoor pig farms in the UK can lead to high nitrate leaching losses and accumulation of surplus N in soil. We investigated the residual effects of three contrasting outdoor pig systems as compared to an arable control on nitrate leaching and soil N supply for subsequent spring cereal crops grown on a sandy loam soil during 1997/98 and 1998/99 harvest seasons. Previously, the pig systems had been stocked for 2 years from October 1995 and were designated current commercial practice (CCP, 25 sows ha−1 on stubble), improved management practice (IMP, 18 sows ha−1 on undersown stubble) and best management practice (BMP, 12 sows ha−1 on established grass). Estimated soil N surpluses by the end of stocking in September 1997 were 576, 398, 265 and 27 kg ha−1 N for the CCP, IMP, BMP and continuous arable control, respectively. Nitrate leaching losses in the first winter were 235, 198, 137 and 38 kg ha−1 N from the former CCP, IMP and BMP systems and the arable control, respectively. These losses from the former pig systems were equivalent to 41–52% of the estimated soil N surpluses. Leaching losses were much smaller in the second winter at 21, 14, 23 and 19 kg ha−1 N, respectively. Cultivation timing had no effect (P〉0.05) on leaching losses in year 1, but cultivation in October compared with December increased nitrate leaching by a mean of 14 kg ha−1 N across all treatments in year 2. Leaching losses over the two winters were correlated (P〈0.001) with autumn soil mineral N (SMN) contents. In both seasons, spring SMN, grain yields and N offtakes at harvest were similar (P〉0.05) for the three previous pig systems and the arable control, and cultivation timing had no effect (P〉0.05) on grain yields and crop N offtake. This systems study has shown that nitrate leaching losses during the first winter after outdoor pig farming can be large, with no residual available N benefits to following cereal crops unless that first winter is much drier than average.

Notes: Abstract. Soil organic carbon stocks to 1 m for Brazil, calculated using an updated Soil and Terrain (SOTER) database and simulation of phenoforms, are 65.9–67.5 Pg C, of which 65% is in the Amazonian region of Brazil. Other researchers have obtained similar gross results, despite very different spatial patterns mapped due to use of different methods.

Notes: Abstract. The effects of rice-straw management (incorporation, burning or removal) on soil organic carbon content and physical and hydraulic properties were determined after five years of rice–wheat cropping in a sandy loam soil in northwest India. Soil organic carbon content was greater with straw incorporation and straw burning than with straw removal, and aggregation status, total porosity, pore-size distribution, bulk density, dispersion ratio and soil strength were correspondingly improved. The treatment effects were confined mainly to the 0–5 cm depth. Water retention was less with straw burning than straw removal, owing to increased water repellency of the soil surfaces. Cumulative infiltration and its rate after five hours were greater with straw incorporation than straw burning or removal. Air entry values were unaffected by straw management; however, the values were greater after rice harvest than after wheat harvest.

Notes: Abstract. A field study was conducted to assess the effect of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP), applied at a rate of 1 kg ha−1, on nitrous oxide (N2O) emissions, forage production and N extraction from a grassland soil after cattle slurry applications in autumn and spring. Nitrous oxide emissions were measured daily or weekly using the closed chamber technique. DMPP efficiency after slurry application was lower in spring (16.7 °C mean soil temperature) than in autumn (11.4 °C mean soil temperature). Thus, DMPP was able to maintain soil mineral N in the ammonium form for 22 days and reduce cumulative N2O emissions by 69% in autumn, while in spring its effect on soil mineral N lasted for 7–14 days, reducing cumulative N2O losses by 48%. Furthermore, application of DMPP after slurry did not decrease biomass yield or N uptake.

Notes: Abstract. Nutrient losses from arable land are important contributors to eutrophication of surface waters, and phosphorus (P) and nitrogen (N) usually act together to regulate production of Cyanobacteria. Concentrations and losses of both nutrients in drainage water from pipe drains were studied and compared in 15 crop rotations on a clay soil in southwest Sweden. Special emphasis was placed on P and it was possible to evaluate critical components of the crop rotations by flow-proportional water sampling. Total P concentrations in drainage water were generally small (0.04–0.18 mg L−1), but during two wetter years out of six, high P concentrations were measured following certain management practices, including ploughing-in lucerne (Medicago sativa L.) and fertilizing in advance without incorporation into the soil to meet the needs of several subsequent crops. This resulted in average flow-weighted concentrations of total P between 0.3 and 0.7 mg L−1. In crop rotations containing green manures, green fallow or leguminous leys, there was also a risk for increased P losses after these crops were ploughed in. The losses increased in the order: cash crops 〈 dairy with grass 〈 dairy with lucerne 〈 monoculture with barley 〈 organic farming with cattle slurry 〈 stockless organic farming with green manure. P balances varied between −9 and +8 kg P ha−1 and N balances between +4 and +35 kg N ha−1. The balances were not related to actual leaching losses. Phosphorus losses in drainage from set-aside were 67–82% of those from cash crops grown in ploughed and P-fertilized soil at the same site, indicating a high background P loss from this clay soil.

Notes: Abstract. Changes in surface soil properties of a savanna Alfisol under cultivation with applications of manure and inorganic NPK fertilizer were evaluated after 45 years of annual cropping. Soils from treatments with fertilizer only, fertilizer in combination with farmyard manure (FYM) at both high and low rates were compared to soil from a control receiving neither fertilizer nor manure. The high rate of FYM and fertilizer significantly improved soil aggregation, increased C, N and P status, while reducing soil penetration resistance. The results showed that there is a need to use both manure and inorganic fertilizer to maintain soil fertility in savanna soils under continuous cultivation.

Notes: Abstract. Vertisols are among the most common, high-potential soils in the central highlands of Ethiopia, where over 88% of human and 77% of the livestock population are located. Productivity from these soils is constrained by severe waterlogging due to their physical properties and intensive rainfall in summer. Traditionally, farmers plant late in the season to avoid the waterlogging, which results in harvest yields that are far below optimal. To bridge this yield gap, the broad-bed and furrow system for surface drainage has been introduced. Despite reported yields of various crops, little is known of the on-site and off-site impacts of this system. Consequently, four land preparation methods viz. (i) broad-bed and furrow (BBF), (ii) green manure (GM), (iii) the traditional system of ridge and furrow (RF) and (iv) reduced tillage (RT) were compared on standard runoff plots for 5 years (1998–2002) at Caffee Doonsaa in the central Highlands of Ethiopia. Runoff, sediment, organic carbon and nutrient (organic nitrogen and available phosphorus) losses were determined during the last two years (2001 and 2002). Over 50% of the seasonal rainfall was lost as runoff, regardless of the treatment, with significantly more of the excess water running off BBF and RT treatments in both years. The BBF system drained 67% and 54% of rainfall as runoff in 2001 and 2002, respectively, compared with 61% and 53% from the RT system during the measurement period. Although not statistically significant, the largest sediment and total nutrient losses tended to be from the BBF. The effect of the treatments on total nutrient loss and enrichment ratio was inconsistent. The nutrient concentration in the eroded sediment was greater than that of the originating surface soil but was strongly correlated. The effect of the land preparation methods was significant and varied with crops. Recommended options for best crop productivity are BBF for lentil and RT for wheat and tef.

Notes: Abstract. Soil organic matter (SOM) controls the physical, chemical and biological properties of soil and is a key factor in soil productivity. Data on SOM quantity and quality are therefore important for agricultural sustainability. In 1990, an experiment was set up at Saria, Burkina Faso on a sandy loam Lixisol to evaluate long-term effects of tillage (hand hoeing or oxen ploughing) with or without 10 t ha−1 yr−1 of manure and fallowing on SOM and N concentrations and their distribution in particle size fractions. The field was sown annually to sorghum (Sorghum bicolor [L.] Moench). Ten years later, total organic C and total N, SOM fractions and their N concentrations, and sorghum yield were determined. Continuous sorghum cultivation without organic inputs caused significant losses of C and N in the hoed and ploughed plots. However, addition of manure to hoed plots was effective in maintaining similar levels of C and N to fallow plots. Without manure, SOM was mainly stored in the size-fraction 〈0.053 mm (fine organic matter, FOM). SOM was mainly stored in the size-fraction between 0.053 and 2 mm (particulate organic matter, POM). In plots with manure and in fallow plots, the addition of manure more than doubled POM concentrations, with levels in tilled plots exceeding those of the fallow plots, and the highest levels in manually hoed plots. Nitrogen associated with POM (POM-N) followed a similar trend to POM. Hoeing and ploughing led to a decline in sorghum grain yield. Manure application increased yields by 56% in the hoed plots and 70% in the ploughed plots. Grain yield was not correlated with total SOM but was positively correlated with total POM. This study indicated that POM was greatly affected by long-term soil management options.

Notes: Abstract. The impact of different tropical farming systems on soil quality was examined using a systematic sampling strategy. Total organic C, pH, extractable P, exchangeable K, bulk density, water stable aggregates, microbial biomass C, cation exchange capacity, soil depth, and clay content were determined. An assessment framework, including a minimum data set, linear scoring functions and weighted additive indices, was used to evaluate the soil quality of a tropical farm growing various crops in Hainan, China. Soil quality was evaluated according to four functions: water availability, nutrient availability, rooting suitability, and erosion resistance. Our results showed that soils were intrinsically lacking in nutrients and vulnerable to degradation, and that these problems were exacerbated by inappropriate management. There was strong evidence that long-term rubber farming caused soil acidification, soil compaction, and depletion of organic matter and nutrients. By contrast, conservation practices in coffee plantations protected or improved organic matter concentration and soil structure, resulting in higher soil quality indices.

Notes: Abstract. The practice of large phosphorus (P) additions to agricultural land has resulted in an increased depletion of limited mineable rock phosphate resources, P accumulation in soils with an increased risk for P losses, and intensified eutrophication and deterioration of water quality in recipient water bodies. A number of measures have been used to reach balance between P inputs and outputs in agricultural systems, with the goal of achieving improved P use efficiency, sustained high crop yields and reduced P losses. This paper discusses how this goal may be achieved. Results from a Swedish long-term fertility experiment combined with results of a P leaching study using a selection of soils from the fertility experiment are used to evaluate the effects of a balanced P system on yields, soil P levels and P leaching. Three P fertilizer application strategies are compared (zero P, replacement P, and a treatment where surplus P fertilization was used to achieve a rapid increase in the soil P status). The replacement P strategy appeared to be the most sustainable system but P fixation in this system must be accounted for. When surplus P rates were applied, increased crop yields were counterbalanced by poorer use efficiency and P accumulation in soil. Topsoil P content was a poor predictor of P leaching. Instead, balancing P inputs and outputs represents a first step in the management of P losses, but additional, site-specific measures are required to counteract site-specific factors responsible for P losses.

Notes: This paper uses the Longitudinal Survey of Immigrants to Australia to analyze the determinants of the level and growth in earnings of adult male immigrants in their first 3.5 years in Australia. The theoretical framework is based on the immigrant adjustment model, which incorporates both the transferability of immigrant skills and selectively in migration. The cross-sectional and longitudinal analyses generate similar findings. The level and relative growth of earnings are higher for immigrants with higher levels of skill and who are economic/skills tested migrants, as distinct from family based and refugee migrants. The analysis indicates that immigrant economic assimilation does occur and that in these data the cross-section provides a good estimate of the longitudinal progress of immigrants. The findings are robust across statistical techniques.

Notes: The article considers a very simple type of hedonic regression model where the only characteristic of a commodity is the commodity itself. This regression model is known as the country product dummy method for calculating country price parities in the context of making international comparisons. The paper considers only the two country or two period case and introduces value or quantity weights into the regression. The resulting measures of overall price change between the two countries or time periods are compared to traditional bilateral index number formulae. It is shown how the Geary Khamis, Walsh and Törnqvist price indexes can be obtained as special cases of this framework.

Notes: There are concerns that the unprecedented economic boom which Ireland experienced in the second half of the 1990s has raised only some living standards and has widened income gaps. This paper analyzes Ireland's income distribution in comparative perspective, to understand how Ireland's distribution changed and how it compares to other rich countries. We begin with OECD (Organization for Economic Cooperation and Development) and the Luxembourg Income Study (LIS) data to compare Ireland's degree of well-being and inequality with other advanced countries. We also look in some detail at alternative sources of Irish income and their implications for the trends in income inequality in Ireland from 1994 to 2000. For instance, we examine the top of the distribution using data from the administration of the income tax system. We conclude that the spectacular economic growth in the past decade has seen the gap in average income between Ireland and the richer OECD countries narrow dramatically. However, this growth has not greatly affected the Irish ranking in terms of income inequality. Ireland remains an outlier among rich European nations in its high degree of income inequality, though still falling well short of the level seen in the United States. In the end, we find that Ireland's new-found prosperity provides a “social dividend,” and choices about how it is used will fundamentally affect whether the current high level of income inequality persists into the future.

Notes: In this paper we present a new industry-level database to analyze sources of growth in four major European countries: France, Germany, Netherlands and the United Kingdom (EU-4), in comparison with the United States for the period 1979–2000. Aggregate labor productivity growth is decomposed into industry-level contributions of labor quality, ICT and non-ICT capital deepening and TFP. A small set of service industries is mainly responsible for the acceleration in ICT capital deepening in both regions, but their contribution to growth is lower in the EU-4 than in the U.S. TFP in these ICT-intensive services accelerated in the U.S. in the 1990s, but not in Europe. In addition, widespread deceleration in non-ICT capital deepening in the EU-4 has led to a European labor productivity slowdown.

Notes: Different spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation faced by different households. In this paper we measure the degree of inequality in inflation across U.S. households for the period 1987–2000. The broad picture that emerges from our results is that over our whole sample period there are substantial differences in the inflation experiences across U.S. households. We find that the cost of living increases were generally higher for the elderly, in large part because of their health care expenditures, and that the cost of living of poor households is most sensitive to the, historically large, fluctuations in gasoline prices. Still, when looking at the whole population, we find that individual households that are confronted with high inflation in one year do not generally face high inflation in the subsequent year as well.

Notes: The country-product-dummy (CPD) method, originally proposed in Summers (1973), has recently been revisited in its weighted formulation to handle a variety of data related situations (Rao and Timmer, 2000, 2003; Heravi et al., 2001; Rao, 2001; Aten and Menezes, 2002; Heston and Aten, 2002; Deaton et al., 2004). The CPD method is also increasingly being used in the context of hedonic modelling instead of its original purpose of filling holes in Summers (1973). However, the CPD method is seen, among practitioners, as a black box due to its regression formulation. The main objective of the paper is to establish equivalence of purchasing power parities and international prices derived from the application of the weighted-CPD method with those arising out of the Rao-system for multilateral comparisons. A major implication of this result is that the weighted-CPD method would then be a natural method of aggregation at all levels of aggregation within the context of international comparisons.

Notes: U.S. households have increasingly used mutual funds to own equity outside of retirement accounts owing to two developments. The first is a decline in equity mutual fund loads, which are negatively correlated with stock ownership rates, which have doubled owing to greater ownership through mutual funds. The second is improved confidence in future family finances. Both effects are consistent with recent models of equity participation, in which lower asset transfer costs and lower income risk induce equity investing by middle-income households, who—in practice and owing to diversification considerations—are more likely to indirectly hold stocks through mutual funds.

Notes: This paper examines the relation between fluctuations in the aggregate value of equities and the adequacy of households’ saving for retirement. Using more recent data than most studies on this topic, we find that many and perhaps most households appear to be saving adequate amounts for retirement, and that there is almost no link between aggregate equity values and the adequacy of retirement saving. A simulated 40 percent decline in stocks has little effect on the adequacy of saving. The substantial growth in equity values and ownership in the 1980s and 1990s did not lead to a surge in the adequacy of retirement saving provisions. The results occur because equity holdings are concentrated among households with significant amounts of other wealth.

Notes: In this paper, I analyze the impact of social security wealth, retirement payments, and living expenses during retirement on people's retirement savings in general, and on their individual pension holdings in particular, using micro data from a 1996 Japanese household survey. I confirm a replacement effect of social security on saving for all types of households and on individual pensions for self-employed households only. This suggests that the social security assets of self-employed households are less than their optimal level of annuitized assets and that they would increase their demand for individual pensions if social security benefits were to be reduced.

Notes: This paper proposes a social welfare framework in which to analyze the relationships between growth, trends in inequality, mobility, and social welfare. An application of the framework to worldwide and regional data on per capita GDP suggests a lack of convergence at the world level, opposite trends in convergence in various regions of the world, and a fairly low level of mobility or re-ranking between countries over time.

Notes: A formulation for incorporating Life expectancy information into empirical economic welfare calculations is presented. In an application analyzing the economic progress of the African continent during the 1990s due consideration of life expectancy factors substantially modifies the conclusions drawn from standard welfare calculations.

Notes: Did global income inequality rise or fall over the last decades of the twentieth century? The answer depends on how cross-country income comparisons are made. Exchange rate comparisons suggest that inequality rose whilst the purchasing power comparisons of the Penn World Table suggest it fell. We show that both measures of real incomes lead to biased international income comparisons. Exchange rate comparisons ignore the relative price of non-tradables, whilst the fixed price method underlying the Penn World Table is subject to substitution bias. The contradictory trends are due to growing dissimilarity between national price structures increasing the degree of bias in each method. When we correct the income data to eliminate bias we find no compelling evidence of a significant change in world inequality.

Notes: Equivalence scales are used to enable welfare comparisons across heterogeneous households. In this paper, we propose to use the achievement of a certain level of functioning as the identifying assumption for the derivation of equivalence scales. This will allow us not only to deal with welfare comparisons between households of different size and composition, but will also enable us to incorporate other characteristics (such as location and employment status) in the creation of equivalence scales for welfare comparisons. The paper applies this approach to create equivalence scales for the functioning “shelter” using Belgian and Italian data. The analysis shows that the income differences associated with different characteristics only play a small role in explaining differences in functionings. An important policy message is therefore that compensating people for functioning shortfalls in monetary terms may not be sensible.

Notes: This paper analyzes distributional changes over the last quarter of the twentieth century. We focus on four distinct distributions: the distribution of hourly wage rates, the distribution of annual earnings of individuals, the distribution of annual earnings of families, and the distribution of total family income adjusted for family size. Both male wage rate inequality and family income inequality accelerated during the early 1980s, increased at a slower rate through the early 1990s and then stabilized at a high level through the early 2000s. The similarity in the timing of changes in these two distributions has been used as evidence that increased family income inequality primarily reflects increased inequality of wage rates. We show that other important factors were also at work.

Notes: The Human Development Index (HDI) uses GDP per capita to measure “command over resources,” which implicitly makes the strong value judgment that inequality and insecurity do not matter. This paper presents revised estimates of the Index of Economic Well-Being (IEWB) for the United States, the U.K., Canada, Australia, Germany, Norway and Sweden for the period 1980 to 2001 and demonstrates that replacing an index of the log per capita incomes with our IEWB as the “command over resources” component in the Human Development Index (HDI) affects the level and trend of the HDI, even among affluent nations. Because the IEWB recognizes four dimensions of command over resources (Current effective per capita Consumption flows, Net societal Accumulation of stocks of productive resources, Income Distribution and Economic Security), its use has a particularly large impact where underlying trends in these components diverge (e.g. the U.K. or the United States).

Notes: This paper is an attempt to translate empirically some of the categorizations of human development reviewed by Alkire (2002). It compares the estimates of human development obtained on the basis of Sen's (1985) capability approach, Narayan et al.'s (2000) dimensions of well-being, Cummins (1996) domains of life satisfaction and Allardt's (1993) comparative Scandinavian welfare study. To obtain these estimates of human development use is made of techniques developed in efficiency analysis, an approach rarely applied to the study of consumption and standards of living (see, however, Lovell et al., 1994). Our database is the British Household Panel Survey. Our findings vindicate the multidimensional approach to human development but show a great empirical resemblance between the four conceptual approaches to well-being.

Notes: Income per capita and most widely reported, non- or non-exclusively income based human well-being indicators are highly correlated among countries. Yet many countries exhibit higher achievement in the latter than predicted by the former. The reverse is true for many other countries. This paper commences by extracting the inter-country variation in a composite of various widely-reported, non-income-based well-being indices not accounted for by variations in income pre capita. This extraction is interpreted inter alia as a measure of non-economic well-being. The paper then looks at correlations between this extraction and a number of new or less widely-used well-being measures, in an attempt to find the measure that best captures these achievements. A number of indicators are examined, including measures of poverty, inequality, health status, education status, gender bias, empowerment, governance and subjective well-being.

Notes: This paper analyzes how inflation-induced erosions of nominally defined amounts built into relevant tax rules (“bracket creep”) alter distributional and revenue-generating properties of income taxes and social insurance contributions. Using a multi-country tax-benefit model, it provides quantitative estimates for Germany, the Netherlands and the U.K. In the absence of automatic inflation adjustment mechanisms, effects on individual tax burdens can be substantial, even with low inflation. Bracket creep is found to reduce tax progressivity. At the same time, overall tax revenues increase. In terms of tax systems’ equalizing capacities, which depend on both these factors, the second effect dominates: if tax systems were left unadjusted then inflation would lead to lower and slightly more equally distributed household incomes. However, existing inflation adjustment regimes in the Netherlands and the U.K. successfully prevent large tax burdens changes.

Notes: When comparing poverty across distributions, an analyst must select a poverty line to identify the poor, an equivalence scale to compare individuals from households of different compositions and sizes, and a poverty index to aggregate individual deprivation into an index of total poverty. A different choice of poverty line, poverty index or equivalence scale can of course reverse an initial poverty ordering. This paper develops easily-checked sequential stochastic dominance conditions that throw light on the robustness of poverty comparisons to these important measurement issues. These general conditions extend well-known results to any order of dominance, to the choice of individual versus family based aggregation, and to the estimation of “critical sets” of measurement assumptions. Our theoretical results are briefly illustrated using data for four countries drawn from the Luxembourg Income Study databases.

Notes: Equivalization of incomes for household composition is accepted practice when measuring poverty but other variations in needs are rarely acknowledged. This paper uses data from two U.K. household surveys to quantify the extra costs of living associated with disability. The extra costs of disability are derived by comparing the “standard of living” of households with and without disabled members at a given income, having controlled for other sources of variation. Logit and ordered logit regressions are used to estimate the relationship between a range of standard of living indicators, income, and disability. The extra costs of disability derived are substantial and rise with severity of disability. Unadjusted incomes significantly understate the problem of low income amongst disabled people, and thereby in the population as a whole.

Notes: The deficiencies of the Deininger and Squire data set on household income inequality are well known to include sparse coverage, problematic measurements, and the combination of diverse data types into a single data set. Yet many studies have relied on this data due to the lack of available alternatives. In this paper we show how the UTIP-UNIDO measures of manufacturing pay inequality can be used, with other information, to estimate measures of household income inequality. We take advantage of the systematic relationship between the UTIP-UNIDO estimates and those of Deininger and Squire. The residuals from this exercise provide a map to problematic observations in the Deininger and Squire data, and the estimated coefficients provide a way to construct a new panel data set of estimated household income inequality. This new data set provides comparable and consistent measurements across space and through time.

Notes: This paper makes a systematic comparison of four approaches to multidimensional poverty analysis based respectively on the theory of fuzzy sets, information theory, efficiency analysis and axiomatic derivations of poverty indices. The database was the 1995 Israeli Census that provided information on the ownership of various durable goods. There appears to be a fair degree of agreement between the various multidimensional poverty indices concerning the identification of the poor households. The four approaches have also shown that poverty decreases with the schooling level of the head of the household, first decreases and then increases with his/her age and with the size of the household. Poverty is higher when the head of the household is single and lower when he/she is married, lowest when the head of the household is Jewish and highest when he/she is Muslim. Poverty is also higher among households whose head immigrated in recent years, does not work or lives in Jerusalem. These observations were made on the basis of logit regressions. This impact on poverty of many of the variables is not very different from the one that is observed when poverty measurement is based only on the income or the total expenditures of the households.

Notes: Income redistribution studies on the macro–economic level have been undertaken in Denmark for the years 1938–39, 1949, 1955, and 1963. By use of national accounts figures and all other available statistics, it was on certain assumptions possible to distribute public sector income and expenditure by income groups.A quite different approach is used in a Danish redistribution study on the micro-economic level for 1971, which relies solely on the comprehensive data from the family budget survey for that year. Unfortunately this study only relates to employee households.This paper deals with the 1963 and 1971 studies. First it describes and discusses the differences in methodology between the two studies and indicates some ideas for future studies in this field in Denmark. In the following sections some main results of the two studies are given, briefly for the 1963 study and more comprehensively for the 1971 study. The studies show the great and growing strength of the policy of redistribution through public sector income and expenditure in Denmark.It is the opinion of the authors that the appearance of redistribution studies based on comprehensive family budget surveys makes for a substantial improvement of redistribution figures, and that the purely micro-level frame of reference makes it possible to interpret the results in a more satisfactory way than before. Furthermore, the appearance of detailed input-output based national accounts data should bring about further improvements in redistribution figures through better data on indirect taxes and subsidies as well as supporting data which are necessary to link the micro and macro levels in a consistent way.

Notes: It is often discussed that inflation introduces a substantial, arbitrary and regressive redistribution of income and wealth under even mild inflation. But after a quarter century of experience with inflation in postwar Japan, very little is known about these costs of inflation on an empirical basis. Due to the complexity of the evaluation of the redistributional impact on Japan, the present paper analyzes the effects of inflation on individuals or groups as wage earners, debtors and creditors, taxpayers, and holders of real estate.The main results of the present investigation suggest that the Japanese inflation for 1955–75 did not seem to introduce much inequality in the income (flow) account in the economy, but that the inequality between households has appeared more in the wealth (stock) account, especially between the house-owner groups and non-house-owner groups. These observations are mainly derived from the following investigations; (i) the wage lag hypothesis about inflation, even if not wrong, does not seem acceptable when applied to the entire period (1955–75) as well as to each of the five sub-periods; (ii) there has been a substantial transfer of real purchasing power from households to non-financial corporations, and, to a lesser extent, to government entities in the debtor-creditor redistribution; (iii) among households, the most substantial redistribution takes place from the non-houseowners to houseowners with land, because of the huge amount of capital gains from the rapid increase in the price of real estate relative to the prices of other assets or the consumer price index, except for the last three years of rampaging inflation.

Notes: Preliminary estimates of the total incomes system of accounts (TISA) are provided for 1959 and 1969. They extend conventional accounts to include all consumption services produced by government and households as well as by enterprises, but define household purchases of durable and semi-durable goods as investment. Acquisitions of capital throughout the economy, intangible as well as tangible, and not only in the business sector, are included in capital accumulation along with, for tangible capital, net revaluations, that is capital gains net of increases in the general price level. Imputations are offered for non market consumption and capital accumulation, most prominently in unpaid household work and education. Much of government output, particularly police services and defense, is recalculated as intermediate, along with expenses related to work, while media services, treated by the United States Bureau of Economic Analysis (BEA) as business purchases of intermediate product, enter into TISA consumption. Subsidies are included in the value of product, as are services of volunteers and imputations for the underpayment of military conscripts and of jurors. Separate accounts are offered for the national income and product, business, nonprofit institutions, government enterprises, government and households.The ratios of BEA to TISA Net National Product were 81.4 percent and 76.5 percent in 1959 and 1969, respectively. BEA national income was 74.1 percent of the corresponding TISA net national income in 1959 and 69.6 percent in 1969, reflecting a greater per annum rate of growth of TISA net national income, 7.49 percent, as against 6.82 percent for the corresponding BEA national income.BEA gross private domestic investment, restricted to business acquisitions of tangible capital at original cost, was estimated as only approximately 22 percent of comprehensive TISA gross domestic capital formation in 1959 and some 20 percent in 1969. The BEA net private domestic investment growth rate of 7.32 percent per annum from 1959 to 1969 may be compared with a TISA net domestic capital formation growth rate of 9.42 percent.

Notes: This paper describes a study designed to provide quarterly estimates of the real capital stock of the United States by sector and industry, which is being undertaken by the Conference Board. It surveys the history of wealth estimation in the United States, and goes on to describe work now in progress both in the Bureau of Economic Analysis and by private researchers. It then continues with a description of the methodology being used in the Conference Board study.

Notes: Abstract. The regulatory regime for contaminated soils and groundwater in the UK is risk based. Indeed, the definition of contaminated land in UK law requires the presence, or likelihood, of significant pollution or harm before affected land meets the statutory test of being contaminated land. In dealing with contamination, a risk management approach is used that also requires the consideration of wider land-use planning priorities, the costs and benefits of remedial action, and the goal of achieving sustainable development. A parallel risk-based framework is adopted for polluted groundwater. The risk assessment process adopted for contaminated groundwater in the UK follows a tiered structure. A simple conceptual model is developed from desk study and site reconnaissance. This model is then used as the basis for designing a site investigation programme, the sampling being undertaken to test assumptions within the model as well as to develop it further. The Environment Agency (England & Wales) has developed a package of tools to aid this tiered approach. This paper describes the integrated risk assessment and risk management processes for contaminated groundwater in the UK, with emphasis on the tools and methods developed. It explains the importance of a conceptual understanding (or model) to all tiers of risk assessment and subsequent risk management.

Notes: Abstract. Sustainable management of nutrients in agricultural systems is critical for sufficient production of nutritious foods and to minimize environmental pollution. In this overview, we discuss some of the most important factors influencing nutrient cycling, and how practices for sustainable nutrient management can be optimized. In most cases, problems are associated with excessive use of nutrients (manures, other organic amendments, and inorganic fertilizers). Options for dealing with such problems at the farm level include: reducing nutrient inputs to balance exports, increasing the land area on which manures are applied, and export of excess nutrients from the farm in the form of value-added products. These strategies can be used singly, or in combination. Nutrients in the human food chain are often not recycled back to primary crop production. To manage such issues, and avoid regional nutrient accumulations, we need to develop a better understanding of large-scale nutrient flows, and develop policies to manage them. We stress the importance of scale when considering nutrient management in the future.

Notes: Abstract. The practice of large phosphorus (P) additions to agricultural land has resulted in an increased depletion of limited mineable rock phosphate resources, P accumulation in soils with an increased risk for P losses, and intensified eutrophication and deterioration of water quality in recipient water bodies. A number of measures have been used to reach balance between P inputs and outputs in agricultural systems, with the goal of achieving improved P use efficiency, sustained high crop yields and reduced P losses. This paper discusses how this goal may be achieved. Results from a Swedish long-term fertility experiment combined with results of a P leaching study using a selection of soils from the fertility experiment are used to evaluate the effects of a balanced P system on yields, soil P levels and P leaching. Three P fertilizer application strategies are compared (zero P, replacement P, and a treatment where surplus P fertilization was used to achieve a rapid increase in the soil P status). The replacement P strategy appeared to be the most sustainable system but P fixation in this system must be accounted for. When surplus P rates were applied, increased crop yields were counterbalanced by poorer use efficiency and P accumulation in soil. Topsoil P content was a poor predictor of P leaching. Instead, balancing P inputs and outputs represents a first step in the management of P losses, but additional, site-specific measures are required to counteract site-specific factors responsible for P losses.

Notes: Abstract. Sustainable nutrient management includes economizing on finite natural resources such as fossil energy and limited phosphorus (P) resources. Arable farms with exclusively crop production are characterized by large nutrient export in farm products. In the long term, nutrient export from soils and losses must be balanced by adequate inputs of fertilizers, biological N2 fixation or recycled products from the human food system. Critical issues associated in particular with arable systems discussed in this paper include organic matter depletion and lack of synchronization between nitrogen (N) release from organic N pools (such as plant residues and green manures) and crop demand, leading to N losses and/or N deficiency. Further critical issues identified include efficient use of indigenous soil P and applied P fertilizers and, especially in organic systems, risk of depletion of P and K, which if realized reduce soil fertility and limit production. The risk of enrichment of trace elements to levels toxic to soil microbes, plants, animals or man is also discussed. Suggested measures for managing these critical issues include choice of crop rotation, residue and green manure management.

Notes: Abstract. The intensity of animal production around the world has increased substantially during the last half-century, which has led to large problems with the disposal of manures and waste waters. The focus of this paper is on the development of national policies to improve the nutrient management of concentrated animal feeding operations (CAFOs), where nutrients are invariably in surplus. To create proper nutrient management strategies for CAFOs, and to avoid environmental problems when surplus nutrients enter air, soil and water, we need to know the number of animals/birds in the unit, the quantity of manure/slurry produced, how this material is stored and handled and how much land is available for manure spreading. In this paper, we discuss the development of nutrient management strategies for CAFOs in Europe and North America, and the voluntary measures and environmental regulations related to this. For the planning of nutrient management to be comprehensive and efficient, we need expertise from several disciplines. This planning includes development of: animal diets that reduce the amounts of excreted nutrients; efficient storage and land application technologies; land application programmes to optimize yields and reduce nutrient losses; and strategies for use of excess manure outside the farm. Also, large-scale efforts involving many stakeholders (farmers, governments and private industry) are needed to solve problems with nutrient imbalances over the long term. Efforts along these lines include manure relocation, alternative uses of manures, nutrient trading, and a general extensification of animal agriculture. The overall guiding principle for policies and planning should be a balance of nutrients, on farms as well as at larger scales.

Notes: Abstract. To establish strategies for sustainable nutrient management, the priority of each identified element for different user groups and the issue of data transferability from one scale to the next need to be addressed. This is important to avoid developing policies and strategies using inaccurate data. This paper provides a thorough background on such issues and provides data from specific case studies to reflect the impact of scale on the usability and transferability of data. These data show that using information obtained in a laboratory setting for larger scales can generate major errors. Data are also provided regarding the spatial variability in total N and total P measured at different sub-watersheds within a large watershed. Results from this case study indicate that there is a definite spatial variability in N and P loadings, which makes it difficult to transfer and extrapolate from data measured at one sub-watershed to the entire watershed. Therefore, it can be concluded that using either measured or simulated data obtained at a small scale to respond to questions for larger scales may be erroneous. Such difficulty may be due to the inherent spatial variability in soils, nutrients, biology and other features of the landscape.

Notes: Abstract. This paper describes the development and application of a simple empirical model describing differences in water movement through a cracking clay soil at Brimstone Farm, Wiltshire, UK. An extended data set comprising readings of soil water tension has been collected from an area of 9 m2 instrumented with 4 nests each of 3 tensiometers. The cracks are responsible for considerable differences both in water pathway and flow magnitude. Variations in water flow suggested by changes in soil-water tension are described by a model developed using ‘ModelMaker’ and applied separately to each profile nest. The model envisages water flow to occur through three soil layers, and to be partitioned into matrix and macropore flow components. Water is lost via drainage to clay tile drains at 60 cm depth. Water flow between layers is described as a function of the hydraulic gradient using Darcy's Law, with additional drainage from structural voids within the soil. Differences in the effective hydraulic conductivity describing slow and rapid flow components equate to macro and matrix flow for each tensiometer profile. The results illustrate heterogeneous patterns of flow through a soil block and demonstrate that a comparatively simple model is able to represent satisfactorily water flow dynamics through a cracking clay soil.

Notes: Abstract. To evaluate the effect of sea salmon sludge on soil and ryegrass yield and quality, five treatments were tested (30, 60 and 90 t ha−1 of sludge, inorganic fertilizer and control). The sludge contained 16% dry matter (DM), 0.13% total N and 1.6% P. The sludge increased ryegrass DM yield, P and Na content, but decreased K concentrations in soil and plants. Sludge can be applied successfully on to land, but its addition should be complemented with inorganic nutrients (N, K). The high Na content of the sludge may limit repeated application, but the main benefit is its P content.

Notes: Abstract. Soils contaminated with organic chemicals are now widespread in industrialized and developing countries, and the risk assessment and remediation of such contaminated sites is a priority. However, containment and remediation strategies are complicated in many cases by the range of contaminants present and the historical nature of the contamination. Research has increased our understanding of the behaviour of organic contaminants in soil and the factors that control their behaviour. There is a fundamental need to understand and, where possible, quantify the bioavailable fraction as well as the total concentration of contaminant present in soil: the bioavailable fraction is key to toxicity or biodegradation. To quantify these fractions, a large number of techniques have been employed, ranging from organic and aqueous based solvent extractions to the use of biota. Many studies have been carried out investigating the use of chemical techniques to describe bioavailability, which could be used in the assessment and remediation of contaminated land. The aim of this review is to consider the behaviour of organic contaminants in soil, highlighting issues of bioavailability, and then to discuss the relevance of the various methods for assessing risk and potential remediation of organic contaminants in soil.

Notes: Abstract. Fertilizer and manure application rate and timing are often based on the optimal nitrogen rate and not on potassium (K) requirements. This can lead to excess or shortage of K depending on the crop and rotation. In grass-dominated agricultural production, including many organic farming systems, K has become a critical element, especially in areas dominated by coarse-textured or organic soils. In this paper we review K management in relation to long-term sustainability of both the soil resource and the production of crops of high yield and quality. One question for the future is whether we can adopt management options that favour efficient use of K and secure a sustainable future for global K reserves. For example, is it possible to enhance the release rate of K from soil mineral sources so that we require less fertilizer K from K-bearing salt deposits? A reduction in external K inputs requires improved on-farm recycling of K in order to reduce losses. We also need a better understanding of soil processes and soil-plant interactions and decision-support tools to predict the potential K release from mineral weathering. Certain areas dominated by young, clay-rich soils can potentially supply enough K, whereas other areas with coarse sandy or organic soils have a very low weathering potential and would thus need external inputs of K.

Notes: Abstract. Changes in agricultural subsidies in Europe and the ready availability of fertilizers have allowed a spatial decoupling of livestock and crop production. This has increased the flow of nutrients that occurs between farms compared to within individual farms. In terms of nutrient cycling, mixed farms provide the opportunity to re-integrate aspects of agricultural production. The degree of integration between crop and livestock production is denned by the reliance on the use of home-produced feed compared to imported feed, and is independent of intensity. Management of inputs and/or internal flows offers the scope to improve nutrient use efficiency (NUE) on mixed farms. Greatest uncertainties in calculating NUE are associated with variation in yield and composition of home-produced feed, and consequent manure composition. Three key areas are addressed to highlight the interchange of nutrients (and risks for losses) between crop and livestock production; (i) the role of livestock diet in manipulating the amount and availability of manure nutrients; (ii) the impact of manure management on nutrient losses; and (iii) nutrient management through the integration of crops and livestock in rotations. While not all the associated issues are unique to mixed farming, these three areas all influence NUE.

Notes: Abstract. This paper highlights the principal problems related to the recycling of municipal wastes to arable land and outlines future solutions. History reveals that transport of sewage with water was introduced early (2500 bc), but only some Asian societies, which did not utilize sewage flushing, redistributed toilet wastes to arable land effectively. Nutrient flow analyses in developed countries indicate a withdrawal of 20 kg N and 3kgP ha−1 yr−1 from arable land because of non-return of organic human wastes. Limited reuse of municipal organic wastes in agriculture in several European countries is often seen as a question of waste quality. However, we believe that despite acceptable quality levels only minor progress in recycling has been achieved. Higher water contents in organic wastes than in harvested crops and, consequently, high costs for drying or transportation of wastes, often in combination with non-optimal plant nutrient composition, will remain the bottleneck which restricts the recycling of nutrients in wastes. One solution is to extract nutrients out of organic wastes and thereby derive concentrated compounds similar to those in inorganic fertilizers that can be redistributed and applied to soil. The challenge for modern sewage treatment systems is to shift perspective from removal to recovery of nutrients.

Notes: Abstract. The Pan-European Soil Erosion Risk Assessment (pesera) model was evaluated using existing soil erosion data collected under various types of climate, vegetation, landscape and soil conditions. The data used represent a variety of typical Mediterranean land uses such as winter wheat, vines, olives and bare, stony land prevailing in hilly areas. Using this data, the model was calibrated for sediment transport by overland flow and results compared to measured soil erosion values from runoff plots and a watershed on a monthly basis. The performance of the model was assessed statistically, showing that it can be satisfactorily used for predicting soil erosion rates under the conditions included in the study. The overall model estimate including all the available experimental data was 0.69 t ha−1 yr−1 with a maximum error of 1.49 t ha−1 yr−1. After validation, the model was applied to a small watershed (60 ha) of great ecological importance for the sea turtle Caretta caretta. For this purpose, soil and vegetation maps were compiled from all the necessary data for applying the model. The model was run for three years using daily data from an existing nearby meteorological station. The predicted and measured soil erosion rates for a 7-month period were 0.31 t and 0.18 t, respectively. Application of the model to each mapping unit showed the over-riding importance of land use for sediment generation under the given climatic conditions. Bare land, occupying 5.5% of the watershed area, generated up to 69% of the total sediments estimated for the watershed. It is concluded that the pesera model can be used as a regional diagnostic tool under a range of soil, topographic and climatic conditions for identifying the best land use type and vegetation cover to protect hilly areas from soil erosion. The calculated overall root mean square error for the model is 0.06 t ha−1 yr−1, compared to a soil erosion rate of 0.04 t ha−1 yr−1, which can be tolerated for protecting the area for the sea turtle.

Notes: Abstract. The compilation of a database of soil carbon and land use is described, from which models of soil carbon dioxide emissions across the United Kingdom (UK) can be run. The database gives soil organic carbon, sand, silt and clay contents and bulk densities weighted to reference layers from 0 to 30 cm and from 30 to 100 cm depths. The data are interpolated from information on soil types and land use on a 1 km grid across the UK and are used to estimate soil carbon stocks. For 1990, the baseline year for the Kyoto Protocol on carbon emissions, the estimate is 4562 Tg soil organic carbon in the top 1 m of soil across the UK, with an average density of 18 kg m−2. The data can be reported by layer (e.g. 54% in topsoils) and country (e.g. 48% in Scotland) as well as by soil and land type.

Notes: Abstract. We examined the use of soil quality (SQ) assessment to predict soil productivity and stability as a component of site potential for rangelands. Two minimum sets of data were compared for the SQ assessment within an area of relatively uniform climate. Data set 1 consisted of total soil N, topsoil depth, effective profile depth (EPD), and grade of structure, thus incorporating only soil chemical and physical properties. Data set 2 included exchangeable soil potassium, EPD, soil water retention capacity at wilting point, a soil slake test, and a nutrient cycling index. The interrelationships between soil properties and plant growth characteristics (i.e. total and herbage yield) were investigated and interpreted by statistical analysis and expert knowledge. By performing multiple regressions for each data set against the plant growth characteristics, we identified the contribution of each data set variable to the variability in plant characteristics and, thus, the predictive potential of each variable and data set. Within data set 1, EPD was important and in data set 2 the nutrient cycling index, which is a landscape function index derived from soil surface attributes, played the most important role in predicting potential. Principal component analysis was used to provide weighting factors for each indicator. We then transformed and combined observed indicator values for each data set using weighting factors and scoring functions into an additive soil quality index (SQI) varying in value from 0 to 1. The SQIs, with values greater than 0.8, provide optimum conditions for high yield.

Notes: Abstract. Saprolite is formed from bedrock weathered in situ that retains the structure and fabric of the parent rock. Landscaping in hilly and rugged topography with unavoidable land levelling exposes saprolites, which are often associated with poor growth of trees and shrubs. In Malaysia, the suitability of saprolites derived from basalt, granite and schists for growing trees and palms was assessed from their physical and chemical properties. Following FAO guidelines all the saprolites were adjudged to be unsuitable due to wetness, shallowness and low chemical fertility as the main limitations.
