In: Assiut Journal of Agricultural Sciences 2007.v.38(2)Summary: Three contaminated soils at Helwan, EI-GabaJ El-Asfar (Cairo governorate) and Arab EI-Madabeg (Assiut governorate) were chosen in a leaching column experirnent for 8 weeks to study the effect of certain organic materials on the mobility of some heavy metals (Pb and Cu) in these soils. The organic materials including ethylene diamine tetra acetic acid (EDTA) as a synthetic organic material as well as poultry litter extract (PLEj, vinasse (V) and humic acid (HAj solutions as natural organic materials, compared to distilied water as a control. These solutions were added to the column every week at levels of 2, 4 and 6 mmols/kg for EDTA, 25,50 and 75 g/L for PLE , 1:2 and l:l dilutions of Vinasse to water as well as pure V, and 0,013,0,019 and 0.025 % for HA.
