摘要：
This article presents the results of the studies on determining the number of soil microorganisms under crops of crop rotations cultivated with the use of different methods of biologization. its dynamics during the growing season, biological activity of the soil, and the rate of decomposition of plant residues. It was found out that cultivation in combined sowing with perennial legumes, their use in fallows, and the use of stubble sideration provide acceleration of the rate of decomposition of decomposition-resistant plant residues of sunflower. barley and winter wheat, as well as an increase of biological activity of soil: in soil under sunflower (on the background of stubble sideration) by 2.2-3.2 times, in fallows by 1.5-2.0 times, in winter wheat plantings on green fallow by 2.8 times, in binary sowing of winter wheat with alfalfa by 3.2 times.
