Methodist. Ivano-Frankivsk College of Lviv National Agrarian University Field studies to study the efficiency of growing energy crops on oil-contaminated soils were carried out on the territory of Bytkiv-Babchynsky oil field of Pasichnyansky territorial community of Nadvirna district of Ivano-Frankivsk region. The following energy crops were used for experimental experiments: sylphia pronizanolista (Silphium perfoliatum L), miscanthus (Miscanthus Giganteus), switchgrass (Panicum virgatum ), energy willow (Salix L), Jerusalem artichoke (Helianthus tuberosus). It is established that the value of the yield of green mass and dry matter of energy crops varies to varying degrees depending on the crop grown on oil-contaminated soils. The content of macro- and microelements in plants, when grown on oil-contaminated soils, increases. Energy willow is a resistant energy crop to adverse conditions when grown on oil-contaminated soil. It can be successfully used for the biological stage of reclamation and phytoremediation. Sylphia pronizanolista also shows signs of resistance to adverse conditions on oil-contaminated soils.

The problem of oil pollution remains one of the most pressing environmental problems today, as the negative environmental impact of fossil hydrocarbons is manifested at all stages of their industrial use: from field development to the use of final refined products for their intended purpose. One of the most vulnerable components of oil-contaminated and refined ecosystems is soil systems, as they accumulate pollutants and can be a key link in the food chain. Self-cleaning of soils from oil pollution is a complex ecobiogeochemical process that does not provide complete restoration of ecosystems for a long time.

Today there are various methods of phytoremediation of oil-contaminated soils, which are characterized by relatively low cost of material resources and stability of the ecological effect, which is the cultivation of cultivated plants to enhance biological processes in soil, optimize physical, physicochemical, agrochemical and other properties. , improvement of ecological functions of soil cover [Banks M. K. 2003, Gerhardt K. E. 2009, Lopushniak V. I. 2021, Pysarenko, P. V. 2020).]. However, this approach is significantly complicated by the high hydrophobicity and toxicity of petroleum products, which contributes to the deterioration of water-air and heat regime, mineral nutrition regime, changes in the ratio of macro-and micronutrients in aqueous 14

solution and soil absorption complex. This causes extreme conditions for germination and development of cultivated plants. Proposed for cultivation in oil-contaminated areas cereals and legumes, sea buckthorn and other crops have a certain level of resistance to adverse conditions of mineral nutrition and germination, but their use is very limited due to the potential for contamination of plant material by petroleum products and their products [Shevchyk L. Z. 2016, Velychko O. I. 2011, Dzhura N. M.

2011, Merkl N. 2005, Pukish, A. (2017).].

On the other hand, the cultivation of crops in oil-contaminated areas that can be successfully used for bioenergy purposes has not been sufficiently studied. At the same time, phytoenergy crops are characterized by high ecological plasticity, resistance to adverse growing conditions. The value of phytoenergy crops increases with dynamic climate change [Kalenska S. 2019]. Recently, numerous studies have been conducted on the prospects of using energy crops for remediation of oil-contaminated areas

[Pysarenko, P. V., & Bezsonova, V. O. (2020). Pandey,20162, Pidlisnyuk,2018, Mohammed, 2015]. Phytoremediation of oil-contaminated soils by growing bioenergy crops accelerates the purification process and reduces the phytotoxicity of the soil environment, and the resulting biomass crop can be successfully used for energy purposes with minimal negative impact on the environment.

The aim of the research is to study the patterns of formation of the yield of bioenergy grasses on degraded oil-contaminated soils to assess their future prospects for remediation of oil-contaminated areas.

The research was carried out in c. Bytkiv of the Pasichnyansky territorial community of the Nadvirna district of the Ivano-Frankivsk region, on the territory of the Bytkiv-Babchynsky oil field. The following energy crops were used for field experiments: sylphia pronizanolista (Silphium perfoliatum L), miscanthus (Miscanthus Giganteus), switchgrass (Panicum virgatum ), energy willow (Salix L), Jerusalem artichoke (Helianthus tuberosus). Crops were planted according to the general scheme: energy willow - 0.3x0.7 m, miscanthus - 0.5x0.7 m, switchgrass - with a distance between rows of 0.5 m, sylphia perforated - 0.5x0.7 m, Jerusalem artichoke - 0, 5x0.7

m.

Control plots were established on the unpolluted territory 300-320 m from the disturbed territory of the oil field. The soil of the control variant is characterized by a low humus content - 2.0%, salt pH is 4.8, and hydrolytic acidity - 3.1 mmol / 100 g of soil. The content of alkaline hydrolyzed compounds of mineral nitrogen - 47 mg / kg of soil, mobile compounds of phosphorus – 94 mg/kg of soil, metabolic potassium -

112 mg / kg of soil. [Lopushniak V& Hrytsulyak H. 2021].

Soil sampling was carried out in accordance with the requirements of the instruction of the Ministry of Environmental Protection "Environmental quality.

Sampling of soils and wastes during chemical and analytical control of spatial (general and local) pollution of environmental objects in areas of industrial, agricultural, economic household and transport sources of pollution ". The organic matter content was determined in accordance with DSTU 4289: 2004 "Soil quality. Methods for determining organic matter". Mobile phosphorus and potassium compounds were determined by the modified Chirikov method according to DSTU 4115-2002, and light 15
