It is shown, that changes in plant component of natural ecosystems for agricultural development naturally leads to a substantial restructuring regimes, processes, and some properties of chernozems. The approach to arable chernozems as a new component of natural ecosystems (agroecosystems) dictates the principles on which to draw when designing farming practices and farming systems.

The paper presents a great variety of anthropogenic effects on chernozems against the background of natural and climatic changes; their consequences are shown as well. Changes in regimes, processes and some properties of chernozems are estimated as genetically predetermined to be a current evolution stage of the soil formation. Different kinds of natural and anthropogenic effects, their complicated interactions that lead to the serious transformation of the structure and properties of chernozems are considered as a methodological platform for scientific research.
