The possibility of bioremediation of territories polluted with oil products in the difficult natural and climatic conditions of the Kola North has been shown. The work has been carried out in the mountain tundra in the north-west of the Murmansk Region. On the site contaminated with diesel fuel 15-20 years ago, the vegetation cover and the organic soil horizon were destroyed. The type of soil on which the research has been carried out is Entic Podzol. During the restoration work, bioremediation methods have been used, and the data about the change of the organic carbon and mobile phosphates content have been obtained. The use of mineral and organic fertilizers increased the carbon of organic humus matter in 1.6-2.1 times and decreased the carbon of petroleum products in 3.3-4.8 times in the soil. At the same time, the fraction of water-soluble carbon of humus decreased in 1.6-2.0 times. The use of fertilizers during bioremediation increased the content of mobile phosphates in 4...
