To improve the conditions for the growth of forest stands on the Berezovy Log Kursk Magnetic Anomaly (KMA) has been conducted applying fertile topsoils, filmed during the development of the deposit. The analysis of the natural growth of the hydro dump is necessary for an integrated assessment of the growing conditions. We carried out it before and after planting on a dump of forest stands. Prior to the applying fertile topsoils, the herbaceous vegetation had not settled on the sand. Natural overgrowth began after the applying fertile topsoils on the surface of the hydro dumps. The northern part of the dump became more active in natural overgrowth. Twenty species of herbs belonging to 10 families were found here, numbering 153 pcs/m 2. Four years later, in six-year-old Scots pine (Pinus sylvestris L.) stands, a richer floristic composition was noted. Thirty species of herbaceous plants have been recorded, of which 54% are with short life-span. Herbaceous vegetation during this period is represented mainly by heterogeneous grass, almost total absence of legumes and small participation of Gramineae. In 40-year-old Scots pine stands, 32 species of grass on the edge and 11 species under the canopy of the plantation were considered, belonging to 13 families. The participation of members of the families of Gramineae and Compositae has increased. Herbs compete with forest stands for moisture and nutrients up to the age of clamping. It is concluded that forest reclamation should be started immediately after fertile application.

Various types of vegetation were tested on the dumps of the Kursk magnetic anomaly (KMA), composed of various rocks and their mixtures, with the improvement of forest growing conditions by land use and without this technique, including five types of shrubby species: sea buckthorn (Hippophae rhamnoides L.), siberian peashrub (Caragana arborescens Lam.), golden currant (Ribes aureum Pursh.), tatarian honeysuckle (Lonicera tatarica L.) and red elderberry (Sambucus racemosa L.). Growth indicators, safety and productivity of breeds were studied. Golden currant was one of the first to be tested, which turned out to be an unsuitable breed for creating protective plantings on dumps without measures to improve their forest growing conditions. On chalk-marl mixtures and quaternary loams, it completely fell out by the age of 12-15 years. Shrubs used in forest reclamation on two-component post-technogenic areas are characterized by different preservation. By the age of 43, the greatest preservation, equal to 50.5%, was noted in the sea buckthorn. It also has the highest growth rates. When choosing shrub species for forest reclamation, it is necessary to take into account their biological productivity, which increases the concentration of nutrients in the substrates and improves their physical properties. The sea buckthorn at the age of 9 has a large phytomass (2368 g), the heaviest leaf mass (396 g) and a total supply of phytomass (143.9 kg /ha) in the stand. The authors recommend using shrub species for laying preliminary crops at the initial stage of reclamation or introducing them into complex plantings in an amount of no more than 50%. Taking into account the soil-improving role of shrub species, it would be advisable to further introduce more durable tree species.
