A significant part of the salinized lands is situated in the continental Asia. These areas include the south of Western Siberia, part of the south of Eastern Siberia, including Zabaikalye and Yakutia, Kazakhstan, the republics of Central Asia and Caucasus, the central part of China, Mongolia, Turkey, Iran and India. In Yakutia the 27,7% of farmland territories consists of frozen salinized soils, mainly concentrated in the central part of Yakutia. Such problems as the distribution of natural salts in the soil profi...

This paper aims to identify the degree of resistance of cryogenic soils exposed to chemical contamination from the Nurbinsky extractive plant in Western Yakutia. It examines the resistance basing on the sorption capacity of soil material, and also assesses their ecological and geochemical state. In this paper we consider homogeneous suprapermafrost-gley, gley podzolized and homogeneous non-gley types of cryozemes. A total of 16 full-profile soil cuts and 185 small trenches were made in depth of 0-10 cm and 10-20 c...
