摘要

Changes in the quantitative and qualitative characteristics of humic substances in soddy-podzolic soils and their particle-size fractions in the course of long-term drainage have been studied under the conditions of pronounced microrelief and different intensities of agrotechnical impacts. The transformation features of humic substances during the periods of specific impacts have been characterized.
