Abstract
The negative impact of man on the environment is noticeably manifested when mining in an open way, in which the prevailing natural landscape is completely disrupted. The object of the study was the Starooskolsk-Gubkinsky iron ore region of the Kursk magnetic anomaly. For the mining technical stage of reclamation of disturbed territories with unsatisfactory growing conditions, common pine (Pinus sylvestris L.) was chosen for research. In the results of studies of post-technogenic areas, elements of mineral nutrition, water, physical and chemical properties of substrates were determined. According to these data, the particle size distribution of such dumps contains from 6 to 43% of silt particles (less than 0.001 mm). Water-soluble salts in the substrates contain a small amount, and the dry residue ranges from 0.12-0.6%. The amount of organic matter is small and reaches only 0.13-0.66%, and mobile phosphorus 1.8-2.0 and exchangeable potassium up to 16 mg / 100 g. These substrates have a high connectivity, showing degree of bonding between individual particles. According to the analysis of the data, the substrates at this object of study are characterized by water-physical properties that make it difficult for tree species to grow
