The paper deals with the degradation of chernozems in the steppe zone during agricultur-al use. It is shown that the change in phytocenoses by agrocenoses causes a change in the thick-ness of the root system and, as a consequence, weakening of the sod process. Studies of the ratio of phytocenosis roots to agrocenosis showed that the more favorable the natural conditions, the more negative impact on the soil-forming process of the soil is provided by modern technologies of wheat cultivation.
