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. These negative processes are shown to transform the structure of microbial cenoses and to decrease the enrichment of soils with microorganisms and accumulation of(More)
The phytocenotic characteristics of cheegrass (Achnatherum splendens (trin.) Nevski) communities developed on solonchaks in the haloxerophytic steppe of western Transbaikalia are given. The specific features of their composition and structure have been revealed. The similarity of the species composition of cheegrass communities is slight or medium. The(More)
The pyrogenic transformation of the microelement content in soils and plants from western Transbaikal (Republic of Buryatia) has been studied. As is found, ground fires, under the studied conditions, lead to the transformation of soil properties and slightly elevated concentrations of Mn, Zn, Cu, and Pb in the surface soil (0–40 cm) and and Mn, Zn, and Pb(More)
The current state of biological diversity and productivity of steppe communities on the chestnut soils of Western Transbaikalia is studied. The communities include plant species of 17 to 20 families. The bases of the communities and their productivity are built by six or seven species, and community diversity is determined by occasional and rare species,(More)
