Systems of elementary soil-generating processes that forms and transform chernozems in different stages of their agricultural development

摘要

Biogenic accumulative processes are shown to have a priority in the formation of chernozems. The stages of agrogenic transformation of soils are due to the use of gradually more complicated technologies of agriculture. When the anthropogenic influence is greater, the number of elementary soil-forming processes that develop grows, and it becomes more complicated to control the fertility of soils.
