Cu, Zn & Ni in chestnut soil in Buryat republic
Gross content and profile distribution of microelements (copper, zinc and nickel) in virgin chestnut soil in Trans-Bailkalia region is researched. Dependence of microelements content from it concentration in parent rocks and some biogeochemical barriers. Biogenic accumulation of microelements in humus horizon and sorption at carbonate-alkaline barrier are determined. Established that gross level of Си, Zn and Ni doesn’t exceed background level and maximum permissible concentration.
