The impact of EDTA, citric acid and poultry manure extract on phytoremediation of Pb by corn in a sandy loam contaminated soil

The plants which can be used to clean up the heavy metals contaminated soils but, for this reason may take years or even decades, because of this chemical and biological treatment uses for phytoremediation. In this study, the potential of corn (hybrid KSC. 704) for accumulation of lead was conducted as an experiment using a completely randomized design with three replications in a greenhouse experiment in a sandy loam soil contaminated with Pb. Citric acid and EDTA were used at concentrations level 0, 0.5 and 1 mmol kg-1 soil and poultry manure extract 0, 0.5 and 1 g kg-1 soil. The results showed that the effect of chelating agents on the shoots and roots Pb concentration, shoots absorption Pb and biological concentration factor (BCF) was (p
