Microbiocenosis of crop soil under the influence of biodestructors

The efficiency of crop production depends heavily on crop varieties and hybrids, technological methods, and plant protection products. However, the basic component of any agro-ecosystem that determines not only the quantity and quality of the crop, but also the ability of plant ontogeny in general, is the soil and its properties. The systematic and irrational use of soil causes its degradation and irreversible loss of organic matter. Straw and organic crop residues are an infinite carbon store for agroecosystems. However, the cycle of conversion of the latter by native soil microorganisms is slow and sometimes ineffective due to the activation of the pathogenic link of the microbiocenosis with their subsequent accumulation in the soil. An ecologically appropriate measure for the destruction of straw and post-harvest residues is the introduction of biological products with cellulosolytic properties. The aim of our study was to determine the effect of bacterial and fungal destructors and their combination on the soil microbiocenosis of the agrocenosis where organic corn residues were produced. The study was conducted using conventional microbiological methods. In a temporary experiment, it was found that the use of biological products Polymix, MicoCell and their combination has a positive effect on the state and functioning of the microbiocenosis. The treatment of straw and organic corn residues with destructors followed by disking contributed to an increase in the cellulosic activity of the studied variants by 2.1–3.2 times compared to the control. In addition, an increase in carbon dioxide emissions in the soil samples studied by 1.6–2.5 times and an increase in the content of microbial biomass by 1.5–3 times compared to the control and depending on the study variantwere recorded. The use of biodestructors with different active microorganisms is not only an economically feasible measure in solving the issue of the conversion of post-harvest residues in agroecosystems, but also environmentally safe, necessary, and agro-technological for the soil formation process.
