Soil-biological methods in monitoring the processes of turning the steppe into a meadow near lake ecosystems of Khakassia

Abstract

The article analyzes the results of the study of microbiological and zoological components in the soils of lake territories in the steppe zone of the Khakassia Republic. It is shown that the transformation of the zoo-microbial complex of the southern chernozem in the process of turning the steppe into a meadow occurs along the way of reducing the biomass of soil microorganisms and a sharp increase in the total and specific metabolic activity of this biomass. At the same time, a sharp decrease in the number of oribatids occurs in the process of turning the steppe into a meadow, with the practical immutability of species richness. At the same time, the composition of the oribatid community is undergoing a radical transformation. These changes in the zoo-microbial complex are associated with changes in the level of soil moisture. The conducted research demonstrated that the identified features of the studied biological and soil indicators (microbiomass, respiration of biomass and metabolic coefficient, the number and species richness of oribatid mites) can be successfully used in the practice of monitoring the process of turning the steppe into a meadow on lake territories in the steppe zone of the Khakassia Republic.
