摘要

The southern part of Western Siberia is a zone of risky agriculture. Herb-grass (Stipa capillata + Festuca sulcata) steppe (formerly predominant in this region) is now 75-80% plowed; it was subjected to anthropogenic impact for no more than 100 years.V. A. Kovda, an outstanding scientist of our time, considered the maximum increase in the productivity of developed lands as a urgent problem [1-3]. Studies of the biological and economic productivity of soils have been conducted under his supervision (and continue to be conducted). Our studies were conducted on the steppe soils of the Omsk region and Altaiskii territory (Kulunda steppe).
