Abstract:
In the present research, anthropo-natural aridization is examined as a complex process manifested in reducing the
available water reserves below the potential level within the respective climatic conditions of the region, reducing the
biological productivity of ecological soil-plant systems, quantitative and qualitative changes at all hierarchical levels of
structural-functional organization of the soil ecosystem materialized in changing the meaning and intensity of
chernoziomic typogenetic processes, the involvement of anthropo-natural processes uncharacteristic of chernozemic
pedogenesis and increasing the degree of inhomogeneity of the soil cover. In this context, anthropo-natural aridization
is a process inherent in the use of chernozems in agriculture caused by the evolution of the pedogenetic environment
under the unidirectional intercalated action of natural soil degradation processes (water and wind erosion, decay) and
physical, physico-chemical and chemical degradation (disintegration-destructuring, compaction, degradation of the
porous space, salinization, solonetization, etc.) in conditions of reducing the role of the biological factor and the process
of humus formation and accumulation within the anthropogenic chernozemic process. The current trend of climatic
conditions in the Pridanubian space, especially reducing the amount of atmospheric precipitation and changing their
regime, increasing the frequency and intensity of droughts, increasing the average multiannual and warm temperatures
are factors that intensify the effects of anthropo-natural aridization of arable chernozems.
