%X Fractionation of copper and lead in wheat rhizosphere were investigated using root-box technique.The soil samples from both rhizosphere and non-rhizosphere were extracted using a sequential extraction procedure.It was demonstrated that the availability of copper in the wheat rhizospere soil increased significantly especially within 2 mm at the top layer,indicated by increase in exchangeable fraction and decrease in carbonate fraction.No such change was observed for lead at the exact same condition.
