Macro- and microelements in Fe-Mn concretions of cryogenic soils

The role of iron-manganese concretions (IMC) in the processes accumulation and migration macro- microelements automorphic loamy soils southern tundra is estimated. features profile distribution properties IMC natural soil (Dystric Cambisols) meadow cultivated (Epistagniс Gelic are identified. Differences composition studied observed both upper part disturbed under anthropogenic impact, lower preserved structural soil. In an active redistribution Pb, Cd, Co, As, Mn, Fe specified. Agricultural reclamation makes to activation concretion formation processes. soils, total amount increases a more expressive Fe, Co down their adsorption bodies from horizons observed. A decrease As content as compared revealed. This possible with high biophilicity its removal system biomass harvest.
