摘要：
Two soils of an experimental station in the Rhine valley near Bonn, cultivated according to IFOAM guidelines, were analyzed for several soil microbiological parameters during a period of 3 years. Analyses included biomass, dehydrogenase, catalase and the four exo-enzymes protease, alkaline phosphatase, sucrase, and beta-glucosidase. Microbial biomass proved to be a useful parameter to observe status and developments of sustainable soil productivity, as well as dehydrogenase and catalase. Exo-enzymes were not well correlated to biomass but they were useful in monitoring specific nutrient cycles.
