Dependence of winter wheat yield on the content and composition of organic matter of typical chernozem

The article is devoted to the study of relationship and determination dependence winter wheat yield on content composition organic matter typical chernozem, its optimal parameters in different by hydrothermal conditions years. research was carried out 2018-2019 a heavy-loamy chernozem experimental field Kursk FARC. Coupled studies Synthetics indicators soil topsoil were 30-meter sites during harvest period. range fluctuations soil, at studied allowed us apply information logical analysis within framework analyzed soil-plant system. A high established, 2018 coefficients transfer efficiency varied from 0.23 0.17, 2019 0.32 0.18. It found that dry biogenicity mobile humus substances, lability humus, microbial biomass has increased, influence decreased. established years significance for formation remained, degree their sometimes nature direction changed. arable layer obtaining Synthetic 5.45-7.24 t/ha favorable year 4.78-7.19 established.
