Phytoremediation involves the ability of plants to remove pollutants and is a promise on low costs and efficient processes for cleaning oil polluted soil. Studies for phytoremediation of soils polluted with petroleum products were critical and were based on monitoring strategies implemented efficiency. These strategies are based on the necessity of treating polluted soil and plant cultivation. Treatment was performed with recycled materials, sewage sludge as fertilizer and fly ash as amendment. The studies took on the characteristics of qualitative and quantitative of Lotus corniculatus crops, plants tolerant to conditions for phytoremediation strategy implemented on polluted soils by 80.5±3.9 g·kg-1 D.M. The use of sewage sludge mixed with fly ash resulted in formation of a layer covering the surface with vegetable grown by 85-94% in July and by 67-83% in August. In Lotus corniculatus crops have not been registered bioaccumulation of toxic metals according to legislation from Romania.
