In experiments carried out on ordinary and leached chernozem, the effect of minimizing the methods of basic tillage and biologization on the fertility of these soils was analyzed. The studies were carried out in stationary and short-term experiments from 1984 to 2017. The effect of various methods and depths of the main tillage, autumn tillage systems, and fertilizers (mineral and organic) on the agrophysical, biological and agrochemical indicators of chernozem was studied. Refusal to carry out farewell processing in grain cultivating crop rotation leads to an increase in the differentiation of the arable layer, a decrease in the fertility of its lower part. The use of annual tillage in the crop rotation resulted in a decrease in the humus content in the soil layer of 0–40 cm by 0.17% (after fertilizers application) and by 0.22% (without fertilizers) compared to the dump processing by 20–22 cm. Organic fertilizers in a complex with minerals during farewell processing promotes an increase in the content of humus in comparison with the surface distribution during surface mulch tillage. A decrease in soil fertility and yield of cultivated crops without dump processing is proved.
