俄语. In the research carried out to study the dynamics of urease activity of ordinary chernozem during the development of resource-saving methods of tillage in the soil and climatic conditions of the south-east of the Central Black Earth Region, it was found that the minimum tillage, including zero tillage in the agrocenosis of a grain-tilled crop rotation, do not lead to a decrease in urease activity of ordinary chernozem, but it increases the dependence of enzyme activity on weather conditions of the vegetation period, which is associated with differentiation of the soil profile. The coefficient of variation of this parameter increases to V=32%, with its value in the conditions of plowing V=27%, in the fallow V=21%, which affects the stability of soil fertility formation processes.
