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

The one of the main types of land degradation that cause the most damage to the state of soil cover is local waterlogging of soils. Only in Russia, about 9 million hectares are currently considered waterlogged, including 5 million hectares of agricultural land. On the lowland plains of the forest-steppe zone of the Central Black Earth Region of Russia, local over moistening of the soil cover creates significant difficulties in the use of arable land resources. Natural factors effects waterlogging are the amount of precipitation and the level of groundwater. The objects of research are virgin and arable soils with different hydromorphic conditions in the Central Russian Upland. The article presents results about humus content and reserves in Chernozems typical, Chernozems leached, Meadow-chernozemics soil, Chernozems-meadow soil and Chernozem wet-meadow soil. According to our investigations the most rich humus soils of the forest-steppe is semi-hydromorphic Meadow-chernozemics soils. Meadow-chernozemics leached and typical soils have an average thickness of the humus horizon of 88 and 85 cm and contain about 8.5 and 8.8% humus in the arable layer. Humus reserves in horizons A + AB is 623 and 629.5 t/ha and in a meter layer is 653.5 and 672.5 t/ha.

Minerals are considered one of the components of the economy of any country. The negative side of technogenesis is the emergence of technogenic landscapes with developed exogenous processes. To prevent and eliminate them, biological reclamation is carried out, the most promising direction of which is forest reclamation. In forest reclamation, preference is given to soil-improving tree and shrub species. The research was carried out in the stands of the Caragana arborescens (Caragana arborescens Lam.) on the dumps of the Kursk magnetic anomaly in the Belgorod region of the Central Federal District of Russia. The work on the test areas was carried out according to generally accepted methods. On the sandy-chalk dump of loose overburden, the karagany cultures completely died by the age of 38. On a two-component technozem, with surface application of a fertile layer on a sand-chalk mixture, karagana showed positive results. The maximum safety (84.2-82.0%) is typical for the first four years of karagana's life. It does not depend much on environmental conditions. The growth of shoots in karagana begins only in the second decade of May. Shoots grow most actively in the third decade of May - 43.8%. The average biomass of one karagana bush at the age of 6 years is 503 g. At the same time, the average mass of one specimen of Robinia pseudoacacia is 2264 g. The total supply of phytomass in the 9-year-old karagana plantation is 69.5 c/ha, which is 2.6 times less than in the robinia pseudoacacia plantation. The reclamation role of caragana leaves is insignificant. The tree-like karagana is rich in mineral elements, which is reflected in their accumulation in substrates. The reserves of nitrogen – 4.06% and calcium – 1.46% are especially large in Karagan. The dump is located in the mining production zone, so the iron content in the assimilating organs of karagany exceeds 4 times the content on zonal soils, and titanium - 1.8 times. A significant part of the chemical elements falls on the green parts of plants. Caragana leaves are supplied with: nitrogen - 26.64 kg /ha, potassium - 1.78 kg/ ha, calcium - 17.52 kg/ ha and magnesium - 4.56 kg/ha. More than half of the chemical elements of root systems accumulate in small roots. When they die off, they enter directly into the substrate. The tree-like karagana can be recommended for forest reclamation of technogenically disturbed lands when mixed with more valuable tree and shrub species
