Probable Mechanism of Influence of Humic Substances on the Production Process of Green Plants

Abstract

Humic substances, being, in fact, black liquor (a product of alkaline hydrolysis of organic matter of natural objects) and are a complex mixture of various organic compounds. They are able to accelerate the circulation of nutrients within plants, increase the permeability of cell membranes, exhibit detoxological properties, optimize the ratio of organic and mineral anions in plants, use some organic components of humic substances as nutrients in plant nutrition and induce the induction of gene expression.
