Qualitative assessment of souls in technogenic landscapes  of Gorlovskiy anthracitous deposit

The paper highlights the results of Morphological studies of soils formed on the outer 30year dumps of overburden and host rocks of the Gorlovskiy deposit and leached chernozem soil. The authors found out that soil covering contains initial, organic accumulative and sod types of embryosimes. Comparative morphological characteristics of soils indicates differences between chernozems and technogenic landscape soils. The results show that soil formation increases concentration of pedogenic organic matter in the soils which is almost equal to that in the black soil. The paper represents qualitative assessment of the soils. The authors calculate the index of specific features which reveals significant differences in the contribution to total variation of different soil properties. The article shows that embryosimes formed on loose sediments are the most fertile. It is established that the level of quality value in rocky soils is determined by concentration of physical clay; in the soils formed on loose rocks it is explained by humus concentration.. The ecosystem is not in a meta-stable climax state; it is developing dynamically, being at the stage of forming sod embryosimes. Therefore, the soil and environmental condition of tailings is satisfactory, as the embryosimes have not been formed after 31 years later the initial phase of technogenesis started. Humus accumulating embryosimes are expected to be formed in the soil covering as well as dry steppe souls on technogenic eluvium and neogenic clays.
