<p>A method for purifying soil contaminated with organic matter, such as an oil, which does not require pH adjustment nor accompanies the emission of a malodor, comprising the step of adding an organic material such as compost completely fermented and fully ripened to soil contaminated with organic matter whereby causing microorganisms indigenous to the soil to be activated to degrade and eliminate contaminant in the soil. Further the organic material serves to adjust the pH value of the soil to a value around the neutrality and at the same time, microorganisms introduced together with the organic material facilitate degrading and removing of the contaminant in the soil.</p> |
