The phytoavailability of various fractions in the tannery sludge amended soils was investigated employing a sequential extraction procedure as well as seedling culture experiment. The results showed that 2 mol/L HCl extractable Cr could be the major fraction of soil Cr available to the plants. When the Cr content in soil was about 220 mg/kg, the Cr concentration of in plant reached maximum of 23.5 mg/kg, which was hardly approachable in field condition.
