Abstract

Soils of forest and tundra ecosystems of Sieda and Khoseda-yu river basins (north-east of East European plain) were studied. Cambisols are typical soils of well drained watersheds, in parent materials represented by silty loams. Soils are characterized by Podzols formed above lower cryomethamorphic horizon. Two stages of pedogenesis were revealed using up-to-date methods and approaches. The basis to determine these stages are the morphological features (structural organization, differentiation of cutan complex) as well as recent and inherited features of pedogenic and cryogenic processes. Upper part of soil has signs of present-day «cryogenic» evolution phase and middle and lower parts of soil profile have features of taiga soil formation occurred during the Middle Holocene could be diagnosed by the presence of fragments of clay cutans and humic pedorelics.
