The genesis and evolution of chernozems in the Carpathian-Danubian-Pontic area were conducted synchronized with the evolution of steppe ecosystem; their driving forces are the soil-plant relationships. The substitution of natural biocenosis with agrophytocenosis led to the minimization reduction of biological component in development of chernozems on the agricultural regime. As a result, chernozems have lost a number of mechanisms for self regulation (self loosening, reproduction of aggregate composition, conservation and rational use of moisture). Their restoration is only possible through renaturation process of pedogenesis by restoring the soil-plant mutual relations. The present research has shown that basic elements of renaturation processes included in the pedogenetical processes are restoration of structural-functional integrated elementary processes in the soil ecosystem.
