Effect of Some Soil Amendments on The mobility of Some Heavy Metal ions in a Contaminated Soil

Abstract
An outdoor pot experiment was carried out at the farm of Agriculture Faculty, Al -Azahr University during the winter season of 2015, to study the efficiency of some amendments (palm waste, gypsum and rock phosphate) on the mobility of Fe2+, Zn2+, Mn2+, Cu2+, Cd2+ and Pb2+. A composite surface soil sample (0-30cm)was collected from south west of Port Said City. The experiment involved 33 pots comprised 11 treatments with three replicates in a completely randomized design. Plastic pots are used of 18 cm inside diameter 22 cm depth and each contains 2.0 kg dry soil. The soils were well mixed with gypsum and rock phosphate applied at the rates 4, 6 and 8 ton fd-1while the soils were well mixed with (palm waste) applied at the rate5 ton fd-1 for all treatments, and then incubated for 60 days in three replicates, beside the untreated soil (control). During soil incubation the moisture content of the pots was kept at the water field capacity, then-at the end of the period of incubation the soil samples were analyzed for some physical and chemical properties, and content of the heavy metals under investigation (Fe2+, Zn2+, Mn2+, Cu2+, Cd2+ and Pb2+). The most important results obtained could be summarized as follows :1- In all treatments pH and ESP values were decreased compared with the control.2-Organic matter, cation exchange capacity, and active calcium carbonate values in the studies soil were increased with increasing the addition of the treatments compared with the control, while bulk density tended to be lower 3-Heavy metal mobility decreased When mixing all of (palm waste, agricultural gypsum and rock phosphate) Generally the results showed the importance of using some amendments such as palm waste, agricultural gypsum and rock phosphate in reducing the mobility of heavy metals (Fe2+, Zn2+, Mn2+, Cu2+, Cd2+ and Pb2+) in contaminated soils.
