Current trends to an increase in the use, production, storage and transportation of petroleum products lead to an increase in the number of accident-related spills of oil products. It, in turn, leads to an increase in the volume of pollutants entering the environment. Toxic components of oil are transformed into even more toxic compounds, which are concentrated and adsorbed in various soil horizons, and are involved in natural feed circuit when it release into the soil. Basic soil processes such as mineralization and respiratory activity are slowed down in soil contaminated with hydrocarbon. In addition, the processes of nitrogen fixation and nitrification are suppressed, the ability of the soil to selfpurification and self-restoration is reduced, its biological value is reduced, and the flora and fauna of the damaged area are depleted as a result of soil contamination with oil products. In this regard, the study, development and testing of technologies for the elimination of the consequences of accident-related spills of oil products is an important task of environmental safety in the modern conditions of the development of the oil industry. The purpose of this work was to create an effective ameliorant for the cleaning of oil-contaminated soils. In the first stage of scientific research it was theoretically established that the application of peat-based ameliorants to the soil with the addition of organic fertilizers (manure or "Karbamid") is optimal because it causes a significant decrease in soil phytotoxicity and enhances the process of destruction of petroleum hydrocarbons. Experimental studies and approbation of the proposed method of oil products spill response were carried out in the second stage of scientific research. It which allowed to afford experimentally proof of the effectiveness of the ameliorant using, which is proposed and theoretically justified in the first stage of research.
