Popis: This paper studies the influence exerted by the degradation of dry steppe grasslands and deflation on the content, reserves, and composition of humus in the chestnut soils of Western Transbaikal. In the deflated soils there is a reduction of stocks of humus and its components. Loss of humin acids in the soil contribute to the development fulvatization humus. A decrease of humic compounds depends from the degree of deflation soils. Dehumidification and arenaceous of deflated soils leads to a sharp drop in their fertility, creating a basis for the development movable sands. These negative processes are shown to transform the structure of microbial cenoses and to decrease the enrichment of soils with microorganisms and accumulation of microbial mass in them by changing the soil humus state.
