Effect of combined treatments and chemicalization agents on soil mycobiota in spring barley crops

The research was carried out in the Central Russian branch of the Federal Research Center named after I.V. Michurin ”. Soil samples for the study were taken from experimental plots of the Tambov Research Institute of Agriculture of the branch of the Federal State Budgetary Scientific Institution “FNTs im. I.V. Michurin ”. For the first time in the northeastern part of the Central chernozem region, research is being conducted to study the microflora and microfauna of typical chernozem. The aim of the study is the effect of combined treatments, as well as the system of fertilizers on the accumulation, structure of the complex of soil phytopathogenic and saprotrophic mycobiota, as well as the microscopic population of the soil in crops of spring barley. As a result of mycological studies, a complex of soil mycobiota was revealed and the dependence of phytopathogens and saprotrophs on elements of agricultural technology was shown. Dump-surface tillage to one degree or another contributed to stabilization of the antagonistic soil mycobiota of the soil. The optimal dose of mineral fertilizer against the background of combined soil treatments has been determined, which makes it possible to successfully restrain the number of micromycetes that cause root rot. It was noted that micromycetes of the genus Pythium were most often found in soils for all crops, less than other phytopathogens. The research results have proved the peculiarity of identifying structures by the improved method.
