Notizen: Summary The amount of copper extracted from soils by EDTA was found to increase with the temperature of extraction. Under controlled conditions of extraction, the amount of applied copper extracted from soils by EDTA decreased during incubation of soils under both moist and dry conditions. The recovery of applied copper by EDTA appeared to be related to the amounts of manganese and iron oxides in the soil. On the basis of comparisons with calcium chloride-extractable copper and isotopically-exchangeable copper it is suggested that EDTA extraction could over-estimate the availability of soil copper to plants.

Notizen: Abstract Element and extractant-specific desorption of Mn, Fe, Cu, and Zn fromSpartina alterniflora detritus was observed. Desorption of a substantial fraction of the total detrital Mn, Fe, Cu and Zn occured rapidly when the detritus was treated with 0.1N HCl or 1 MgCl2. This treatment removed precipitated/coprecipitated and adsorbed trace elements, respectively, suggesting that a large fraction of detritus-bound trace elements are in readily exchangeable, surface reaction sites. The carboxylic acid functional group cation exchange capacity of the detritus also suggests an important role of surface exchange reactions in the dynamics of trace elements during decomposition. The rate and magnitude of changes in the trace element content of detritus has important implications for estuarine biogeochemical cycling of these elements including the potential for biological uptake of trace elements by detritus-consuming fauna.

Notizen: Summary The uptake of trace metals by two plant species (French bean and maize) has been measured on two soils subjected to various waterlogging regimes. Uptake of both manganese and iron was increased due to soil waterlogging, although reoxidation of the soil affected iron more than manganese. Zinc and copper uptake was influenced by a species factor; French bean (Phaseolus vulgaris) showed preferential uptake of zinc, whereas maize (Zea mays) took up copper preferentially. Uptake of cobalt by both species was increased due to waterlogging, following the pattern of manganese. The abilities of these species to take up trace metals from soil followed the pattern predicted by selective extraction of soil for manganese, iron and cobalt, but not for zinc and copper.

Notizen: Summary Lowland rice (RD 3) was cultivated in containers of clay soil submerged with 5 cm water under controlled conditions in the phytotron. Deep placement of urea supergranules 5 cm in the soil significantly enhanced both plant growth and fertilizer efficiency when the plants were cultivated under high light intensity (70 Wm−2). At the highest urea level grain yield increased 119% above the control level, while growth and fertilizer efficiency was not as high when deep placement of calcium nitrate was used. The application of urea prills and calcium nitrate (18.4g Nm−2) in two split doses on the soil surface increased grain yield as much as 91% above the control level. At the lower nitrogen concentration (9.2 g N m−2), the urea prills were more efficient than calcium nitrate as indicated by the grain yield. The height of those plants fertilized by surface application was affected by the concentration and not the type of fertilizer. The number of tillers, however, was significantly higher on urea fertilized plants. When the rice plants were cultivated under low light intensity 930 Wm−2), neither the nitrogen fertilizers nor the method of application had a significant effect on growth and yield.

Notizen: Summary Laboratory incubation experiments were conducted with three clay loam lowland rice soils (Haplustalf) to study the effect of application of three different levels of Cu(0, 1.25, 2.5 ppm) and Mn (0, 10, 20 ppm) in all possible combinations on the changes in the DTPA extractable Zn, Cu, F, Mn and Brays 2 extractable P in soil. The results showed that application of Cu decreased the content of extractable Zn, Fe, Mn and P in soils, the rate of decrease gradually declining with the progress of incubation period. Application of Mn also depressed the content of extractable Cu, Fe and P but increased that of extractable Zn.

Notizen: Summary We report a study of the mechanism by which the response of plants to waterlogging can be modified by soil temperature. Wheat was grown initially in well-aerated soil in a controlled environment room before the soil was flooded with aerated, deionized water. The soil temperature was maintained constant in the range 6–18°C while the air temperature was at 14°C. Waterlogging damage was greater in plants at the higher soil temperatures when the plants were compared at the same chronological age. However, when compared at the same growth stage, the response to soil temperature was little differenti.e. plants subjected to waterlogging for a long time at low soil temperatures exhibited a similar reduction in growth and other properties as those subjected briefly at higher temperatures. The concentration of dissolved oxygen in the soil solution declined rapidly at all temperatures, being almost zero after 36 h waterlogging. Temperature affected rates of change of the concentrations of dissolved carbon dioxide, ethylene, nitrous oxide, nitrite, nitrate, calcium and potassium. The importance of soil-and plant-determined properties in the waterlogging response of plants at different temperatures are discussed.

Notizen: Summary In most arable soils the nitrate availability depends mainly on the quantity of nitrate present in the rooting zone at the beginning of the growing season. Easily mineralizable organic N and the release of non-exchangeable NH4 from clay minerals may in addition control the nitrogen availability during a season. In flooded soils, ammonium is the major form of nitrogen absorbed by plants. Ammonium dynamics in these soils is similar to that of potassium. The availability of both is controlled mainly by the intensity and buffering power for ammonium or potassium, respectively. Basically, intensity of the supply and buffering power for phosphate are the main factors determining the phosphate availability. The determination of the phosphate buffer power, especially in the root zone, however, remains to be difficult. Soil test methods should take into consideration the major factors and processes relevant to the availability of a particular plant nutrient.

Notizen: Summary An assessment of the status of available micronutrients has been made in a long term field experiment on a fixed rotation of soybean-potato-wheat at the Ranchi Agricultural College, Kanke on acid soil. Results of eight years fertilizer applications with lime has resulted in reduction of available micronutrients whereas the FYM application with balanced dose of chemical fertilizers increased the available micronutrients of soil. The maximum loss of 1.0 Zn and 13.2 Fe kg/ha respectively were from the lime treated plots with balanced dose of fertilizers and the highest gain of 0.26 Zn, 1.08 Cu, 13.2 Fe and 54.0 Mn kg/ha respectively were recorded from the FYM treated plots with balanced dose of chemical fertilizers. Organic carbon was significantly positive correlated with av. Zn & Mn, whereas av. Mn significantly negative correlated with pH. Other relationship were found to be non significant.

Notizen: Summary Three tree species,Eucalyptus regnans (F. Muell.),E. obliqua (L'Herit.),Pinus radiata (D. Don) were grown in sand culture with different proportions of nitrate and ammonium. Nitrate Reductase Activity (NRA) was induced in root tissue of all species and in leaf tissue of the eucalypts. An increasing proportion of nitrate resulted in increasing NRA in all species and hence NRA alone is no indication of N-preference. The highest NRA was found withE. regnans, a result which has also been obtained in the mature forest. The growth ofE. regnans was least with NH4 + alone, whereas that ofE. obliqua was least with NO3 − alone. The soils of matureE. regnans forest have a high potential for nitrification while those ofE. obliqua forest show little nitrification. Thus the preference for particular N sources shown by seedlings in culture is supported by related properties of mature forests. It is postulated however, that the inducibility of a high level of RNA in seedlings is more likely a result of a preference for NO3 − than a cause.

Notizen: Summary The migration of common bio-toxic heavy metals in two typical soils of Japan under the influence of various leaching solutions was investigated. The results of the present study have indicated that the Pb and Cu ions were less mobile than those on Zn and Cd. Thus, the former two ions have largely been concentrated in the surface horizon while the latter two have been localised in the sub-surface layers. Ni has exhibited greater mobility than other heavy metals under all the leaching stress in both the soils. It is clear from the present study that Ni, Cd and Zn might pose a greater threat of ground water pollution than Cu and Pb. The specific migration properties of each metal ion varied depending on the nature of the ion and leaching solutions. The major soil factors governing the mobility of heavy metals in the soils have been discussed in the light of the results of the present investigation.
