Abstract The geographical position of the Republic of Adygea determines the development of a wide class of exogenous geological processes (wind and water erosion; flooding, salinization and excessive water saturation, etc.), which may have a destructive effect on the soil cover. About 185.7 thousand ha (55.7% of the total area of 333.4 thousand ha) of agricultural land in the region are subject to weak wind erosion. Of these, 65.3 thousand ha (19.6%) are considered deflationary. 32.8 thousand ha (9.8%) of agricultural land in the Republic of Adygea are subject to water erosion. Lands saturated with water (including waterlogged) account for 64 thousand ha (19.2%). A total of 13.7 thousand ha or 4.1% of the total agricultural land in the Republic of Adygea is occupied by saline soils and solonetzes. Apart from wind erosion, exogenous processes have no significant effect on the state of the soil cover of the Republic of Adygea.

1 Introduction The soil cover is an independent complex natural shell of the globe – the pedosphere, the part of the biosphere which is the most saturated with life, where the processes of weathering and soil formation occur. The patterns of formation and diversity of soil cover, regimes, various properties, and characteristics of soils are determined by the pronounced heterogeneity of bioclimatic and lithological and geomorphological conditions. The specificity of the soil cover of certain regions is manifested in the composition of the soil cover, its structure, as well as in the features of the use of land funds. Soil degradation in most cases occurs under the combined influence of natural and anthropogenic factors, while the anthropogenic influence creates the prerequisites for a sharp activation of natural influences. It is often difficult to distinguish between the effects of natural and anthropogenic degradation factors [1].
2 Soil Cover of the Republic of Adygea Land resources occupy a leading place in the natural and economic potential of the Republic of Adygea [2]. Besides the fact that land is the main and irreplaceable means of production in
