Overcoming the negative impact of oil by the microbial community of the dark gray forest soil and its toxic properties
During the four-year exposure of different doses of oil pollution, the dynamics of microbial respiration quotient(Qr), toxicological characteristics of the dark gray forest soil were studied. With the initial oil content of up to 10%, the normal functioning of the microbial community is restored within 365 days with a content of 15-20% elimination of imbalance of soil processes is observed in 2.5-3 years, after the beginning of the experiment. The absence of direct dependencies between incubation time and toxicological effect of oil-contaminated soil and water extraction from it on plant and animal organisms is demonstrated.
