The concept “soil biophysical fertility: theoretical and applied support”

Abstract

: In terms of the theory of elementary pedogenetic processes, the pedogenetic process represents the totality of the integration processes of abiotic and biotic matter in the composition of the basic soil matter, which represents the first level of integration of matter in the soil, specific to it. Its further evolution is determined by the unidirectional action of humic substances resulting from the operation of the system "living organic matter ↔ dead organic matter". The driving force behind the continuous processes of structural-functional organization of the soil ecosystem are the processes of humus formation and those of accumulation-sequestration and stabilization of organic carbon in the structural aggregates responsible for the functioning of the soil ecosystem materialized in ecosistemic functions, including soil fertility. maintained All processes are performed in relatively balanced biogeochemical circuits of substances. Relative stability of the main diagnostic features. One-way realization of micro-, meso- and macroprocesses of expanded reproduction of soil fertility in closed circuits of substances.
