An integrated approach to the bioremediation of technogenically modified soils has been developed, which has made it possible to create effective phytoremediation systems for the restoration of territories contaminated with waste from the oil and coal industries. Screening of plants resistant to growth on oil-contaminated soils (field peas) and rock dumps of coal mines (grass sorghum) was carried out. A set of measures has been developed for the remediation of oil-contaminated soils, including the addition of sunflower husks, mineral fertilizers, biosurfactants, and humates. The biomass of phytoremediants increases by 31-39%, the indicator of oxidative stress decreases, the oil content in the soil decreases from 5% to 0.4%.
The introduction of a microbial preparation of hydrocarbon decomposers into the oil-contaminated soil and pre-sowing treatment of pea seeds with field solutions of biosurfactants contributed to an increase in growth rates by 20–40%, the content of chlorophylls by 59–70% compared with the control, which indicates an increase in plant resistance to adverse conditions. The effectiveness of the complex application of plants-remediants, microorganisms-destructors of oil products, rhamnolipid surfactants and calcium peroxide was confirmed in experiments on oil-contaminated soils and on rock dumps of coal mines. The oil content in the soil decreased by 5.5-6 times.
It has been established that sea buckthorn in symbiosis with nitrogen-fixing microorganisms of the genus Frankia improves the physicochemical properties of oil-contaminated soil, protects it from erosion and reduces the oil content by 92.7%. This allows us to recommend this species as a promising phytoremediant plant of technogenically modified soils with high oil pollution.
