Ecological and geochemical basis of estimation of agro-landscapes of Ukraine

Abstract

The purpose. To study causal-investigatory correlations between processes of geochemical mi­gration and ecological state of agro-landscapes, their taxonomic grading and quantitative parametrization. Methods. Landscape-geochemical zoning of Ukraine and systemic generalization of agro-ecological, ag­rochemical, hydrochemical, bloclimatic, geomor­phologic, blogeochemical and mineralogical data. Results. Taxonomic grading of agro-landscapes is presented which includes systematization of geo­chemical and ecological processes, factors of agro­ ecological zoning, their quantitative parameters and criteria of estimation. Concluslons. Comblnation of limiting and favorable ecological-geochemical fac­tors of farming agriculture for terrains of regional geochemical landscapes of Ukraine is presented.
