    Notes: Abstract. Results from recent studies of peatland biogeochemistry suggest that appropriate soil water sampling techniques are required in order to advance our understanding of peatland soil systems. In a comparative field experiment, concentrations of inorganic solutes and dissolved organic carbon (DOC) were measured in soil water extracted at a depth of 10 cm beneath the surface of deep peat by three techniques: zero-tension (z-t) lysimeters, PTFE suction samplers, and polysulfone suction samplers. The majority of solute concentrations were broadly similar, but mean concentrations of silicon, DOC, iron and aluminium in water extracted by z-t lysimeters and PTFE samplers were in ratios of 1:5; 1:2; 1:5 and 1:3 respectively. Mean conductivity and concentrations of chloride and hydrogen ion were significantly larger in the z-t lysimeter samples, which had sodium, potassium and magnesium to chloride ratios that were very similar to local rainfall. The z-t lysimeters appeared to sample macropores preferentially, while the suction samplers collected micropore water.

    Notes: Abstract. Demand for water from catchments dominated by upland peat as a source of drinking water supplies in the UK is likely to increase in the future as demand per capita continues to rise (Thomsen 1990) and/or summer droughts increase in frequency (Arnell 1992). Concern has been expressed in recent years over rising colour levels (related to dissolved organic carbon (DOC) and iron (Fe)) from such catchments (e.g. Kay et al. 1989) causing reduced drinking water quality. One of the major causes of increased DOC concentrations is rewetting following periods of relative drought (Mitchell & McDonald 1992). Experimental rewetting of a naturally drained wetland in Mid-Wales over four years was found to substantially increase the concentrations of DOC, and Fe in the pore-water, with peak values of 〉60 mg dm–3 (Fe) and 〉300 mg dm–3 (DOC) after rewetting, compared with typical values of 〈1 mgdm–3 (Fe) and 〈15 mg dm–3 (DOC) under the drained conditions. Seasonal peak concentrations of Fe and DOC have since remained at these higher levels. Rewetting produced a selective enrichment of the 〉5000 to 〈90 000 apparent molecular weight (AMW) material and this fraction was found to yield peak Fe concentrations. Two additional peaks of DOC were also found in the experimental wetland (not present in the control wetland), of 〉90 000 to 〈200 000 AMW and 〉200 000 AMW material. The AMW spectrum of DOC in the experimental wetland changed with season, and the 〉90 000 to 〈200 000 AMW fraction could only be seen in spring, representing a transient pool of carbon that is rapidly transformed in or transported from the wetland. These findings suggest that rewetting of peatland following drought (e.g. due to climate change) has the potential to reduce water quality. Moreover, recent interest in restoration (rewetting) of drained peatlands (Wheeler & Shaw 1995) could create an additional source of DOC rich water.

    Notes: Abstract. There is increasing evidence that phosphorus has been accumulating in the surface horizons of agricultural soils to the extent that some soils represent a potential diffuse source of pollution to surface waters. The relationships between equilibrium phosphorus concentration at zero sorption (EPC 0) of soil and a number of soil physicochemical variables were investigated in the surface layers of arable and grassland agricultural soils sampled from the Thame catchment, England. Soil EPC0 could be predicted from an equation including soil test (Olsen) P, soil phosphate sorption index (PSI) and organic matter content (OM) (R2=0.88; P〈0.001) across a range of soil types and land use. The simple index Olsen P/PSI was found to be a good predictor of EPC0 (R2=0.77; P〈0.001) and readily desorbable (0.02 m KCl extractable) P (R2=0.73; P〈0.001) across a range of soil types under arable having soil organic matter contents of 〈10%.

    Notes: Abstract. Boreholes have been constructed at eight sites on the Permo-Triassic Sandstone and Chalk aquifers to assess the extent of chemical and microbiological contamination emanating from unlined farm manure stores. Slurry along fracture faces in the Chalk was found on cores taken from beneath two stores. Porewaters from the Chalk sites and one of the Sandstone sites were discoloured and showed high concentrations of nitrate, ammonium and organic carbon to depths in excess of 10 m. Although Cryptosporidia and Escherichia coli O157 were found in many of the cattle slurry lagoons, neither were found in the aquifer material beneath. The self-sealing of unlined slurry stores is seen as a crucial step in minimizing leakage. A simple mass balance shows farm boreholes near to contaminant sources are at greater risk than public supply wells. Contaminant modelling shows discontinuing use of an unlined farm manure store will lead to little difference in solute concentrations over the short to medium term. Groundwater is most at risk where the water table is shallow since direct hydraulic connection between the lagoon base and the water table considerably increases the rate of vertical migration. This is of greatest significance for pathogens that are thought to be relatively short lived in the subsurface. Under the majority of situations minimal threat is posed to potable groundwater drinking supplies.

    Notes: As a preliminary step in the development of improved bred varieties an examination has been made of the factors which contribute to the success or failure of white clover (Trifolium repens) in hill land reseeding. Severe restrictions are placed on clover performance and N fixation in many hill areas in Britain by the poor climate, the low pH and exchangeable base status of the soils and the low frequency of effective indigenous Rhizobium strains.Agronomic solutions to some of these problems exist, but experience in mid-Wales suggests the need for new bred varieties with improved adaptation to the prevailing conditions, particular attention being directed to the limitation of N fixation by low soil temperature.

    Notes: Swards based on a mixture of SI 70 tall fescue and S215 meadow fescue were very early in spring, gave high yields for conservation in mid-season and, rested from mid-August, gave good grazing in November-December. Under this treatment, the tall fescue assumed dominance, and the swards were persistent and remained productive. The digestibility of the tall fescue swards was always higher than that of swards based on cocksfoot with which they were compared. During spring and autumn the former sward was better grazed by stock, but the position was reversed in mid-summer. Cattle grazing tall-fescue-dominant swards made better liveweight gains than those grazing cocksfoot swards during November-December.

    Notes: The distribution of natural and cultivated grasslands in relation to climate and the use of various indices and diagrams in studies of crops and climate are discussed. Attempts to establish simple linear relationships between yield and weather components have been disappointing. Studies involving light, theoretical considerations of productivity, adaptation of herbage plants in relation to climatic origin, etc. have proved more useful. Problems involved in extending the work conducted under controlled conditions to the field, are stressed. Particularly important is a better characterization of the environment prevailing in and immediately above swards of different types. The importance of winter survival in Britain is discussed.

    MECHANICAL TREATMENT FOR IMPROVING UPLAND GRAZING (1965)

    Notes: The botanical changes in a wet (Molinia) and a drier (Nardtts) upland pasture that followed a single defoliation by a forage harvester are briefly described. Without fertilizer the bare and litter-covered areas were soon recolonized by the original dominants; with lime and fertilizer the recolonization was mainly by Agrostis spp., even when Agrostis was a minor element in the original sward. These changes were markedly accelerated by the forage-harvester treatment. The results of surface seeding after the forage-harvester treatment are compared with those obtained after rotary cultivation. Contrasting moisture regimes and competitive thresholds led to considerable differences in sward balance and in establishment of sown species, and seeding was successful only on the wetter site. Too rapid regeneration of undesirable remnants was prevalent, but this and other hazards are related to the uneven deposit of litter left by the forage harvester; thick, slowly-rotting accumulations inhibited the redevelopment of rapidly-growing species and germination on seeded areas.

    The cost of living, threshold bargaining and incomes policy1 (1973)

    Notes: For trade union bargainers one of the infallible laws of political economy is that wages lag behind prices. This means that in an inflationary era the real value of the wage to which their members are entitled will be eroded, and some compensation will have to be made for this at the next round of wage negotiations. Therefore, changes in the cost of living since the last settlement will be regarded by trade unions as one of the most important factors to be taken into account in arriving at a new settlement. This is implicit in the statement made by the TUC in 1971 that “it requires pay increases of at least 10 per cent simply to restore the real disposable pay of a union's previous settlement 12 months earlier”. Economists, on the other hand, argue that once an inflation is under way, then economic agents will develop an inflationary psychology—that is, they will expect it to continue and will adjust their behaviour accordingly. If this is correct, trade union bargainers will attempt to anticipate inflation by trying to fix the money wage at a higher level than they would aim for if the price level were more stable.
