Carbon reserves in postagrogenic dry steppe soils of Western Transbaikalia

New data on carbon reserves in the postagrogenic chestnut soils of Western Transbaikalia are given. Quantitative and qualitative characteristics of the formation of element reserves in these soils have been revealed. It has been shown that the ratio between organic and inorganic carbon compounds in the total carbon reserves in dry steppe ecosystems varies significantly. The element reserves are gradually restored in postagrogenic successions and become close to those in similar virgin soils.
