摘要：In the field experiment with the agro-gray soil of the Krasnoyarsk forest-steppe, the improvement of the agro-physical properties was established with the use of organic fertilizers, regardless of their type and application rate. Under the influence of bio-fertilizer and chicken manure introduced into the agro-gray soil, there is a tendency to increase the amount of humus and nitrate nitrogen, mobile phosphorus and the yield of wheat grain. The correlation between the yield of wheat grain and mobile forms of humus is estimated at the average level. Using the method of multiple regression, a model of wheat yield was calculated, according to which it depends on the content of mobile humus substances.
