Abstract
Agricultural use of sludge has been increased as a mean of disposal and beneficial reuse. However, elevated concentrations of heavy metals on land receiving sludge pose publiC concern. The amount of metals uptake by the plants depends on the content of the soil metal, plant species, and soil parameters particularly pH. The aim of this study was to investigate the effect of lime in reducing heavy metals uptake by corn grown in the sludge-treated sandy soil. In addition, the residual effect of lime on heavy metals uptake by fababean grown in rotation with corn was studied. The plants were sampled at the harvesting time beside the grains and pods hull and all samples were examined for heavy metals content [µg/g] and uptake [µg/plant]. The results revealed that lime application to sludge-treated sandy soil decreased Zinc and Nickel in the grains of corn. However, the residual effect of lime in sandy soil decreased Zinc, Nickel, and Cadmium contents of fababean grains and Copper in the fababean pods hull below the recommended toxic levels of these metals. So, it is recommended to apply lime to sludge-treated sandy soil to minimize the uptake of heavy metals by corn and fababean and to reduce the public health effects of these heavy metals.
