The article presents the results of experimental studies on the assessment of the phytotoxicity of soils contaminated with oil products of various fractions (gasoline, diesel fuel, fuel oil) in the process of their microbiological remediation with the introduction of humic preparations. The studies were carried out under the conditions of a vegetation experiment, in which the processes of bioremediation of soils contaminated with various oil products were simulated using microbiodestructors and humic preparations (“Ekorost” and “Gumi”). It has been established that the implementation of bioremediation measures using microbio-destructors does not allow for complete detoxification of soil contaminated with various oil products. The manifestation of detoxifying properties of humic preparations in relation to oil-hydrocarbon pollution of soils during their bioremediation was revealed. The severity of these properties varies and depends on the type of oil-polluting product, its concentration, as well as on the properties of the preparations themselves.
