SALINE SOILS IN THE EASTERN PART OF THE YERGENES

Abstract

On the basis of field research by the authors, carried out in 2005- In 2009, the chemical properties of solonetz soils were characterized the complexes of the eastern part of Yergeny within the Republic of Kalmykia. In Yergeny, the share of saline soils in the upper part of the Yergeny River is 50-75%; the share of saline soils in the upper part of the Yergeny River is 10-25%, in some places up to 25-50 and 50-75% from the complex square. The solonetzes of the studied area include to the superficially saline soils are strongly saline from 20 (fine saline) or 50 cm (deep saline). In light chestnut soils salinization appears deeper than 1 m, less often from 50 sm. Salt composition of solonetzes refers to chloride and chloride-sulfate soils; light chestnut soils belong to sulfate varieties.
