LF slag is a by-product generated from refining steel and because of increase of steel industry is it mandatory to find a manner to reuse this material in an efficient way. Utilization of industrial waste materials in the improvement of problematic soils is a cost efficient and also environmental friendly method in the sense that it helps in reducing disposal problems caused by the various industrial wastes. The surface of soil suffers an acidification process especially under the conditions without liming, soil pH values less than 5.5 ensure conditions for strong solubilization of pollutants and their translocation into plants. The experiment was designed with five experimental variants with three repetitions for each variant: V1 (control), V2 (1 t/ha), V3 (2 t/ha), V4 (3 t/ha) and V5 (5 t/ha) associated or not with mineral fertilization. The biological material used in this experiment was wheat. The results indicated that slag can be used successfully to correct soil acidity, to improve the soil physical and chemical properties and the increase of soil fertility. Research has followed the translocation of heavy metals from soil in wheat grains. The analyzes were performed for copper, cadmium, cobalt, nickel, lead and zinc from grains of wheat. The content of heavy metals in all samples were less than the maximum allowable limits.
