Intensive land use for agriculture in the nearest future could involve depleted industrial fields contaminated by oil. For Kazakhstan, a country with a wide territory and a lack of water resources, it is important to apply eco-friendly cleanup technologies when planning extensive agricultural development. My work aimed to investigate the oil spills bioremediation with the application of the ex-situ method to clean the soil and water and for use in agriculture. There are 2 main stages: cultivation of oil destructing microorganisms; soil and water treatment in the presence of destructor. After watering the soil oil products go up on the water surface and make it possible for microorganisms to use them as the energy source and make it reusable for further purposes.
