Manifestations of antropo natural aridization in the agrogenic layer of arable chernozems: factors, mechanisms

Abstract

The anthropo-natural aridization of arable chernozems is a complex process that involves not only the reduction of water reserves in the soil but also the radical change of the water regime materialized in the formation of hydrophysical profiles that differ significantly from those characteristic of native chernozems. The current evolution of arable chernozems is influenced by the intercalated action of aridizational and degradative processes and involves changes in the meaning and intensity of typogenetic processes at all hierarchical levels of structural-functional organization of the soil ecosystem.
