Change in properties of manmade soil in reclamation using peat–diatomite improver

The urgency of the environmental problems in mining-disturbed areas is obvious due to the high manmade load. The natural landscape is changed, air is polluted, soil and water bodies are contaminated with heavy metals, manmade accidents take place, etc. Recultivation of such territories is usually complicated by the lack of the required reclamation layer of soil. It is necessary to select the most cost-effective reclamation method using materials that can rehabilitate disturbed lands. In this regard, the use of new improvers is a fairly promising and effective way to recover the ecological characteristics of areas of land violations. The article presents the results of applied research into reclamation horizon formation using peat–diatomite improver (PDI). Planting of grass vegetation on reclamation ground surface, with regard to regional environmental optimization measures and zonal features, can ensure creation of sod to prevent deflation and water erosion. The results of the experimental data on the use of PDI on variously violated lands, either contaminated by oil or containing increased concentrations of copper ions, are analyzed.
