Aim of project

As a result of activization of geochemical (losses of soluble chemical elements with liquid compounds of surface snomelt runoff) and anthropogenic (removal of solid compounds of runoff by snowmelt flows from plowing layer of slopy soils) erosions practically healthy and high-fertile soils have lost their excellent quality within the limits of the last 50 years, and the territory of the catchment of great and small rivers had converted into the areas of ecological catastrophe. The suggested project is directed at solving the relationship of geochemical and anthropogenic erosions, removal of carbon and calcium with liquid and solid compounds of surface snowmelt runoff as applied to the belt soils of dissected landscapes.

Expected results

Total removal due to surface snowmelt runoff of dissolved chemical elements, which is not in excess of 10 kg per ha including 4 kg carbon per ha, is presented to be ecologically safe on zonal soils of forest steppe (dark grey forest soils and podzolised, leached and ordinary chernozems). When the type of snow melting and amount of solid atmospheric precipitation are changed, geochemical and anthropogenic erosions greatly increase, which contributes to essential removal of chemical elements from soils of different catena’s positions, to their accumulation in negative elements of landscapes ant transit delivery into hydrographic network. The study of substance composition of liquid and solid compounds of runoff and the size of accumulation of solid compounds on different positions of the landscape permit to start elaborating the assessment of ecological damage on development of erosional processes.
