| Abstract | INTRODUCTION Sewage sludge, being an organic waste, is a rich source of plant nutrients including N, P, K, Ca, Mg, Fe, etc. (Martinez et al., 2003). Sewage sludge also contains high concentration of heavy metals that could accumulate in soil and may be taken up by plants. Cabbage, amaranthus, spinach, radish, lady’s finger and forage grasses grown in sewage sludge amended soils showed higher concentrations of Cd, Cr, Co, Cu, Pb, Ni and Zn as compared to those grown in unamended soils (Sekhar et al., 2002). Sewage sludge is applied for growing several vegetables including radishes in Esfahan. The possibility, therefore, exits that heavy metals could be taken up by vegetables grown in sewage sludge amended soil and could be transferred into the food chain. It was, therefore, the objective of this study to investigate the effect of increasing rates of sewage sludge applications on possible accumulation of Zn and Cu in soil and their uptake by radish. |
