One of the most serious problems of agriculture in our country is soil degradation, which leads to a decrease in soil fertility and often to its withdrawal from agricultural use. About 44 million hectares of land in Russia are currently not used in agricultural production, of which 20 million hectares is arable land.

The loss of its production function by the soil is primarily associated with a negative balance of nutrients. As a result of the current difficult socioeconomic situation in the country, which led to a low level of fertilizer use, a significant part of the crop yield is formed due to soil fertility reserves achieved in 1970–1990 by intensive chemicalization. If this trend continues, the removal of nutrients from the soil with the harvest may 4–5 times exceed their supply with fertilizers in the coming years. Currently, 36.4 million hectares of arable land, or 31 %, have increased acidity, 54.5 million hectares, or 46 %, have a low humus content, 25 million hectares, or 22 %, have a low content of mobile phosphorus and 11.5 million hectares, or 10 %, have a low content of exchangeable potassium [1].

In recent years, the soil has been considered not only from a production point of view but also from an environmental point of view. Soil degradation damages such ecological functions of the soil as the habitat of numerous macro- and microorganisms, due to the vital activity of which humus formation processes occur, gas exchange in the biosphere is carried out, nutrients are kept from leaching out, plant nutrients become available, and anthropogenic pollutants are detoxified. To restore the production and ecological functions of the soil, agricultural biologization begins to become a modern trend in the development of agriculture. The main task of agricultural biologization is to create a self-sustaining and selfregenerating soil environment due to natural factors. In addition to such techniques as the use of crop rotation systems with the sowing of perennial grasses, microbiological fertilizers and plant protection products, Notill technologies, the introduction of organic fertilizers, the development and application of fertilizer organomineral mixtures are a promising direction and element of agricultural biologization.
