The results of the study of the properties of urban soils of the city of Sibay located in the mining region of the Republic of Bashkortostan are presented. A specific feature of the studied territory is a significant distribution of soils with strong and very strong physical degradation, rocks buried under dumps, and replantozems in reclaimed areas. At the same time, the traditional way of life of the population in Sibay determines the presence of territories occupied by vegetable gardens and orchards, where culturozems (agrochernozems, Hortic Anthrosols) are formed. These soils have a generally positive effect on the soil cover of city by increasing the area of healthy soils. Morphological descriptions of the major groups of soils—native, anthropogenic surface-transformed. and anthropogenic deep-transformed—are presented. The diversity of the considered soils is controlled by the functional use of the land, which determines the nature of the anthropogenic load. The degree of soil degradation (as judged from the thickness and bulk density of the humus-accumulative (A + AB) layer) as is moderate for ekranonozems (sealed soils) and weak for cultivated agrochernozems. An increase in the bulk density is accompanied by deterioration in the structural and aggregate state of soils and a decrease in soil porosity. A significant increase in the thickness and improvement of the structural state of the humus-accumulative horizon has been noted for agrochernozems of vegetable gardens.
