FUNCȚIILE SANO-ECOLOGICE ALE FRACȚIUNII LABILE A SUBSTANȚELOR ORGANICE DIN SOL: O ABORDARE CONCEPTUAL-TEORETICĂ

Abstract

Through the concept of ,,soil resources,” the ,,system of soil organic substances” was defined as the entirety of discrete particles of organic residues of biogenic origin, non-humic biomolecules, humic substances adsorbed and integrated into the mineral conglomerate (matrix) of the soil. The driving force of the functionality of the organic substances system is the labile fraction of organic substances, which represents a complex heterogeneous bioenergetic system consisting of organic dead matter and the living phase, exclusively determined by landscape conditions. The primary function of the labile fraction of organic substances within the organic substances system involves the continuous provision of bioorganic-mineral resources for its functioning within the soil ecosystem.
