Description:
Oil is considered one of the most dangerous sources of environmental pollution, especially for the soil, as it turns it into sterile soil that is not suitable for animal, plant or any living thing. Therefore, in this research, we will use four methods to treat soil contaminated with crude oil, where animal and plant fertilizers were used at rates of 20% and 40% in each method, with both types active and inactive, on samples of contaminated soil, after preparing these samples they were compared with each other by analyzing the data and the results of scientific experiments held on the samples. Where the results of the treatment of contaminated soil, and by using some of these methods, showed an increase in the ratio of bacteria beneficial to the soil and at the same time an increase in the ratio of organic materials feeding the plant, because of the existence of types of bacteria in these fertilizers that eliminate or feed on the toxic oil compounds that exists in the soil, in addition to this activating and providing the soil again with bacteria that are beneficial to it. After we applied the treatment processes and scientific experiments, it became clear that the method (B1) using animal fertilizer (sheep manure) after adding a quantity equal to 40% of the sample gives the most positive result when treating soil contaminated with crude oil.
