    The issues of land pollution, restoration, and return of land to agricultural cultivation are today. Especially, this is gaining new relevance in modern conditions of military action on the territory of Ukraine and other countries, which causes the reduction of cultivation areas. Therefore, there is a need for maximum cleaning and restoration of polluted soils to ensure environmental and food security. Petroleum hydrocarbons are classified as major environmental pollutants due to their stability and durability in the environment. The influence of petroleum hydrocarbons is caused by direct toxic activity and by the soil environment transformation. The research aimed: to study the effectiveness of probiotics in the technology of soil cleaning and remediation; evaluate the phytotoxic effect of oil-contaminated soil before and after the application of probiotics; to find the optimal concentration of probiotics for the effective cleaning and remediation of soil. The seedling method was used to evaluate the phytotoxic effect of contaminated soil before and after the application of probiotics. Research results showed an ambiguous impact on Pisum sativum and Avéna satíva at different times after pollution. In the initial phase, polluted soil has no significant influence on Pisum sativum. For Avéna satíva soil, become toxic right away after pollution. Phytotoxic effect of Pisum sativum and Avéna sativa decrease by the indexes of seed emergence, roots length, roots weight, underground part length and ground part weight due to probiotics treatment. The high efficiency of biological remediation by probiotics in comparison with soil cleaning in natural conditions is determined in the experiment. Probiotic concentration 1:10 is the most effective of all studied initial concentrations of pollutants. Reducing probiotic concentration leads to a decrease in the efficiency of soil cleaning from petroleum products.
