CHANGES IN SOIL FERTILITY OF THE VOLGA-AKHTUBA FLOODPLAIN AS A RESULT OF THE CONSTRUCTION OF THE VOLGOGRAD HPP AND WAYS TO IMPROVE IT

Abstract

The changes in the productivity of natural biocenoses and soil fertility of the Volga-Akhtuba flood-plain after the construction of the Volgograd reservoir are analyzed. The method of quantitative assessment of the productivity of natural biocenoses, changes in the content of humus in soils and the relative fertility of floodplain soils is given. The effectiveness of various variants of spring-summer releases and enhancement of the natural drainage of the floodplain are shown. The given materials can be used to substantiate the ra-tional use of water, land and biological resources of the Volga-Akhtuba floodplain.
