ESTIMATION OF POPULATION DYNAMICS OF MIXOTROPHIC-SYNTHETIC MICROFLORA OF SOUTHERN CHERNOZEMS UNDER VARIOUS METHODS OF SOIL TREATMENT IN DRY-STEPPE AGRICULTURAL LANDSCAPES

Abstract

With the participation of various ecological groups of microorganisms, the processes of humification and mineralization of organic matter of vegetable or animal origin. This article presents data on the quantitative analysis of mixotrophic-synthetic microflora of chernozem soils depending on the types of treatment used. Depending on the type of treatment in the soil, various conditions of density, aeration, and moisture can form, which affect the activity of microbiological processes. Microorganisms of the mixotrophic-synthetic group have a powerful enzymatic apparatus, they participate not only in the mineralization of organic residues, but also in the synthesis of humic substances. In the work, the dynamics of the number of such microorganisms of the mixotrophic-synthetic group as microscopic fungi and actinomycetes is estimated. The experimental options included four types of soil cultivation: deep plowing, shallow plowing, flat-cut tillage and disking. A quantitative account of microorganisms showed that in all variants of the study there was a high degree of soil enrichment as actinomycetes and microscopic fungi. Mathematical data processing did not reveal significant differences between the experimental options.
