The specifics of the studied soils formed on loam are proved to be of high carbon content in coarse-humus (mor) organic-accumulative horizons and its content is inclined to a sharp decrease with depth. Humus composition is humuc-fulvic in organic horizons and fulvic in mineral horizons. Cryo-surface-gley soils are highly soluble and characterized by the low-average humification degree of organic matter. The humus profile of cryo-hydromorphic soils is formed by a complex of processes such as cryogenic mass exchange, frost retinization, and cryogenic denaturation and coagulation of disperse humus systems.</p>}, number={1}, journal={Biological Communications}, author={Beznosikov, Vasiliy and Lodygin, Evgeniy}, year={2012}, month={Mar.}, pages={107–120} }
