摘要

The soil and plant covers of the vast areas of the clayey semideseit in the Northern Caspian Lowland are distinctly differentiated by meso- and microrelief determining the distribution of moisture with dissolved chemical elements. The largest low-lying landforms termed 'liman' reach dozens and even hundreds of hectares in area, and are occupied by 'liman solods'; smaller mesodepressions stretching over several hectares, and known as 'large padinas', have cheinozem-like soils as typical for their soilcover. The remainder of the area has a patterned, or complex, soil cover corresponding to well-pronounced microrelief Soils of the microhillocks are presented by solonchakous (semihydromorphic) solonetzes under Festuca sulcata--black wormwood communities, soils of the shallow mrcrodepressions are identified as meadow-chestnut soils under forb-grass communities, Light chestnut soils under dry-steppe vegetation occur on microslopes. The difference in height between the microhillocks and microdepressionsis about several dozens of centimeters, whereas the diameters of both are as great as several meters or dozens of meters.
