Industrialization and activities have led to the production of a wide variety of waste materials in the world, imposing different negative environmental consequences.StoneCuttingis a kind of activity that leads to solid waste production. During the cutting and processing of stones, a part of the rock is transformed into rubble.The waste includes unusable rocks, extra material from the ore cutting and sludge from the cooling water deposition. The sludges contain heavy metals such as copper, zinc, nickel, cadmium, chromium, iron, and so on. that can be recycled and reused, using these sludges in various industries. Iron is an essential element for plant growth.Iron deficiency induces chlorosis in young leaves of plants. Diffierent methods are being applied to manage the plant iron deficiency among which, one of the most important is application of synthetic Fe chelates, however, the high cost make This method not affordable. Therefore, it is neccessary to find more effective and cheaper alternatives. In the present study, the possibility of using acid sludge extract for corn was studied.The acid sludge extract was characterized for: heavy metals concentration (iron, zinc, copper, cadmium, chromium, nickel and lead), total nitrogen, available phosphorus, soluble potassium, total sodium, electrical conductivity and pH. The effect of the sludge application on plant growth was examined in a pot experiment for two month. Based on the Fe concentration in sludge acid extract, the soil available Fe increased to 5(S 1 ), 10 (S 2 ) and 15 (S 3 ) mg/kg.The pot experiment was a completely randomized design. Maize, Maxima cultivar was cultivated as the test plant.The grown plants were harvested at the begining of flowering and analyzed for different parameters.The results showed that the highest fresh and dry weight of shoots and root, were in S 1 (equivalent to 0.9 ml/kg soil). The highest iron uptake of shoots and rootswerealso observed in S 1 (equivalent to 0.9 ml/kg soil)treatment.The highest zinc uptake in the shoots was observed in theS 1 (equivalent to 0.9 ml/kg soil)treatment and the highest zinc uptakeof root was in theS 2 (equivalent to 2.68 ml/kg soil)treatment.The highest amount of copper uptake in shootswere observed in S 2 (equivalent to 2.68 ml/kg soil)treatment. The results of this study suggest the use of acid extract as a soil amendment forthe supply of corn iron, although futher studies are required in this regard.
