Functioning of soils in the hummock-hollow ecosystems of the upper Angara region

摘要

The hummock-hollow relief is typical of the Angara region, which determines mottling of the soil cover, its complexity. We examined how microelements (elementary composition), exchangeable Ca and Mg, and biogenic parameters (humus composition, biological activity) behave in soils. The topical problems concerning the studied object are discussed.
