Klimatologie im Dienste der Medizin,d soil as compared with uptake from direct-drilled soil was correlated with seasonal rainfall patterns. Significantly higher quantities of both fertilizer- and soil-derived N were taken up by winter barley than by spring barley, reflecting the longer growth period and higher dry matter yield from the former crop.

However, the subsequent rates of production of CO.-C and mineral-N measured during a 10-day incubation period at 25.C were low and variable, resulting in anomalously low estimates of microbial biomass. The flush of inorganic-P was more consistent and, in mor humus, generally related to biomass-C as measured by the Anderson and Domsch test.

Zentrale Aussagen zum Klimawandele N inputs in the form of commercial fertilizers. Cultivation of increasingly larger areas of land has resulted in substantial losses of soil organic matter and N. Also, the move from slash and burn agriculture to intensively ploughed systems has resulted in losses through increased erosion..The use

Generally, no more than 5 to 15% is lost through leaching and denitrification with most of the remaining N incorporated into soil organic matter. The relatively high efficiency of N use by cut swards reflects rapid uptake of N and the rem
