CHERNOZEMS OF THE SOUTH BAIKAL REGION, THEIR AGRO- AND POSTAGROGENIC TRANSFORMATION

The chernozems of the Southern Baikal region belong to the facies subtype of moderately cold, long-term freezing soils. Therefore, the thickness of their humus horizon is limited by a half-meter thickness and low humus content and reserves. Intensive plowing of chernozems has led to a significant reduction in its thickness to the level of plowing depth. The content and reserves of humus have noticeably decreased compared to virgin soil. Removing the agrogenic impact helps restore the fertility of agrochernozems, but the process of their regeneration in the extremely continental climate of the Southern Baikal region is greatly inhibited.
