Agronomic assessment of humus state of soils

The humus state of soils is determined by the properties and regimes occurring in soils, at the same time the humus state determines the processes of transformation, migration and accumulation of matter, energy and information in soils, their fertility and yield of agricultural crops. The conducted studies have shown that along with the study of the physico-chemical properties of humus substances, including using modern instrumental methods, it is necessary to determine the properties of humus compounds important for its agro-nomic assessment: the effect on Eh and pH, complexing ability, structure-forming ability, anti-pathogenic function, stimulating and inhibiting ability. The necessity of information and energy assessment of the humus state of soils is shown.
