Technogenically disturbed soils of the Kedrovsky coal mine dumps, a branch of JSC MC Kuzbassrazrezugol, located in the forest-steppe of the Kuznetsk Basin, Kemerovo region (Russia), are investigated. The physicochemical characteristics of young soils were studied using the facilities of an experimental polygon for disturbed land reclamation technologies. The following soil variants were studied: typical technosol (technogenic eluvium), organogenic technosol (with application of a potential fertile soil layer, PFSL), and humusogenic technosol (with application of a fertile soil layer, FLS). The humusogenic technosol was found to possess a higher starting lithogenic potential in terms of soil formation, when restoring disturbed soils and their vegetation cover with an increase in species diversity by zonal type. Under favorable climatic conditions and the use of proper agrotechnical technologies, FSL technosols promote the development of grassy ecosystems and activate the process of soil formation. Over time, these soils can approach zonal soil types in terms of their main physical and chemical parameters, including organic matter.
