Özet
The aim of this study was to investigate the existing changes for the contents of some nutrients and heavy metals of soil and root and shoot of corn plant after applications of increased sewage sludge (0 %, 2.5 %, 5 %, 7.5 %, 10 %). Significant increases were found in the contents of Zn, Cu, Mn, Pb, Ni, Cd, and Co of the experimental soil as sewage sludge application were increased. Besides, there were significant changes of the root Zn, Cu, Mn, Co contents by the increased doses of sewage sludge application. it was determined that the root Cu content decreased linearly compared to the control but, the reverse was the case for the Zn and Mn contents. Application of the sewage sludge at the increasing rates affected the plant shoot Fe, Zn, Mn and Pb contents significantly. While there were significant increases for the plant shoot contents of Fe, Zn, Mn and Pb by the applications compared to the control. The increases for the shoot contents in question were linear for the nutrients Zn and Mn. The applications of the different rates of the sewage sludge taken from biological processing foundation for the housing from iskenderun county of Hatay province indicated that there were somehow positive effects on plant soil properties without any heavy metal toxicity effect. It was shown that the sewage sludge applications depending upon the rates leading the resulted heavy metal increases in soil which can cause the heavy metal accumulation and toxicity in the soil in time in the case of applications in sequence during the growing seasons under uncontrolled conditions.
