Abstract	Using the example of a successional form that manifests as overgrown arable land, we have studied the influence of post-agrogenic vegetation, i.e., easily decomposed litter deposits, on the dynamics of the microbiological activity of the soil. The largest deposit of nitrogen and ash constituents supplied to the soil by litter as observed for land that had been fallow for 5 years and a 35-year-old small-leaf forest. The biological activity of the soil, which is determined by substrate-induced respiration, protease activity, and cellulose decomposition activity, depends on the aftereffect of soil cultivation, as well as on the quantity and composition of easy-decomposed litter that supplies the soil. As a result of the optimal combination of these factors, high soil biological activity is observed for land that has been fallow for 5 years. This quite high index is also found in small-leaf forests due to large deposits of litter containing ash constituents.
