“…This problem is particularly relevant for oil producing regions, including the Republic of Tatarstan (RT) that produced more than 3.3 billion tons of oil. The soil of oil contaminated lands loses fertility for many years and leave agricultural circulation [2,5].…”

The study was carried out in the Republic of Tatarstan (Volga Federal District of the Russian Federation) in grey forest middle loamy soil with weak acid reaction of the medium, low humus content, increased content of labile forms of phosphorus and potassium. The soil was deliberately contaminated with oil at a dose of 25 l/m2. There is close positive linear relationship (R2=0.845) between the amount of bens(a)pyrene (BP) and petroleum substances in soil. The BP content in oil-contaminated horizons (0–15, 15–30, 30–45 cm) of soil exceeded the maximum allowable concentration by 10.5–19.5 times that demonstrates a serious threat to vegetable products growing on oil-contaminated lands. Due to oil contamination, the content of most labile forms of nutrients (N, P, K, B, Mo, Zn) decreased and others remained unchanged (Cu, Co) or increased (Mn). At the same time, these changes were not so significant, because the groups of soil supply with labile forms of nutrients, except phosphorus and potassium, did not change under the influence of oil.

Установлено, что под действием нефти в серой лесной почве резко увеличилось содержание общего углерода, снизились емкость катионного обмена, гидролитическая кислотность, содержание подвижных форм азота, фосфора и калия. Глубина трансформации и темпы естественного восстановления агрохимических свойств обуславливались уровнем и давностью загрязнения. Изменения агрохимических свойств, вызванные дозами нефти 20 и 40 л/м2, сохранились в течение не менее десяти лет. Under the influence of oil, the total carbon content in the gray forest soil has dramatically increased. Тhe cation exchange capacity, hydrolytic acidity, and the content of mobile forms of nitrogen, phosphorus, and potassium have decreased. The depth of transformation and the rate of natural recovery of agrochemical properties were determined by the level and age of contamination. Changes in agrochemical properties caused by oil doses of 20 and 40 l/m2 have been preserved for at least ten years.

Much attention is paid to the relationship between bacteria and plants in the process of the bioremediation of oil-contaminated soils, but the effect of petroleum degrading bacteria that synthesize phytohormones on the content and distribution of these compounds in plants is poorly studied. The goal of the present field experiment was to study the effects of hydrocarbon-oxidizing bacteria that produce auxins on the growth, biochemical characteristics, and hormonal status of barley plants in the presence of oil, as well as assessing the effect of bacteria and plants separately and in association with the content of oil hydrocarbons in the soil. The treatment of plants with strains of Enterobacter sp. UOM 3 and Pseudomonas hunanensis IB C7 led to an increase in the length and mass of roots and shoots and the leaf surface index, and an improvement in some parameters of the elements of the crop structure, which were suppressed by the pollutant. The most noticeable effect of bacteria on the plant hormonal system was a decrease in the accumulation of abscisic acid. The data obtained indicate that the introduction of microorganisms weakened the negative effects on plants under abiotic stress caused by the presence of oil. Plant-bacteria associations were more effective in reducing the content of hydrocarbons in the soil and increasing its microbiological activity than when either organism was used individually.
