The invention relates to preservation of the environment, in particular, to soil reclamation polluted by oil and petroleum products caused by accidents and operation losses at production, transportation and every day man's activity. The method is characterized in that dry zeolite is spread over the land area depending upon the rate of soil pollution, simultaneously, nitrogen and phosphate mineral fertilizers are also spread. The initial dose is calculated by formula D = Naz ∙ K, wherein Naz is determined by the difference of levels of potential activity of soil nitrogen fixation and polluted soil area after zeolite spreading, Kaz is selected experimentally. To provide uniform spreading of zeolite and mineral fertilizers the polluted soil is loosed to 25-30 cm. The inventive result is aimed at reducing reclamation cost and soil recovery having different level of nitrogen fixation activity. |
