Abstract
Studies have established that in a layer of 0-20 cm, the density of soil compaction in all fields of crop rotation was characterized as loose (0.83-0.97 g / cm3), while the humus content was medium and high (5.6 - 7.8%). During the drought, an increase in the density of addition was found to be 1.4-1.1 times in all fields of crop rotation, with the exception of pure steam. Reserves of productive moisture were unsatisfactory and amounted to 10.2 for potato cultivation, soy, and wheat – 14.3 and 15.8 mm, respectively, net fallow land had significantly higher reserves of productive moisture, which amounted to 19.7 mm. After harvesting in September, productive moisture reserves in the 0-20 cm layer reached satisfactory values of 25.8-36.9 mm; the maximum reserve was formed in pure fallow land and during the cultivation of wheat.
