DETERMINATION OF THE INFLUENCE OF DRANLESS DEPRESSIONS OF RELIEF ON THE SUSTAINABILITY OF SOIL FERTILITY

К.Ю. Зотова, К.Е. Стекольников

Abstract


Drainless depressions of relief are usual for plains between the rivers Don and Oka. Soils in such depressions located in Verkhnekhavsky district of Voronezh District were studied to assess (i) their physicochemical characteristics and the degree of their hydromorphicity in order to determine the rational for measures aimed at making them suitable for agriculture and (ii) the effect of such depression on the sustainability of soil fertility. Several causes of the negative effects of depressions on arable lands are delineated and approaches to their reduction are suggested.

Keywords


drainless depressions of relief, natural factors, hydromorphicity, anthropogenic factors, arable lands
