Specific Features of the structure of humic substances of podzolic and peaty podzolic gleyey soils

摘要

One of the pressing problems in fundamental knowledge about humic substances is a study of their structural and functional parameters, the transition from the fractional group composition to the molecular fragment level [1], and the creation of the theoretical basis of a science concerned with structurally complex, natural high-molecular-weight substances of soils. Investigations of the principles of the structure of humic substances makes possible a quantitative description of the structure-molecular mass interrelation, which serves as the base for developing a theory of soil stability as well as the creation of substances (preparations) with a controllable composition and reproducible indices for their practical use in the field of environmental protection and agriculture [2, 3].
