Cultivation experiments were conducted to evaluate the efficiency of four phosphate fertilizers including DAP(diammonium phosphate), MPP(mono potassium phosphate), SSP(calcium superphosphate) and TCP(tricalcium phosphate) as stabilizing agents of Cd in contaminated soils. Five molar ratios of P/Cd were tested:0, 2:3, 3:2, 2:1, 4:1. The toxicity characteristic leaching procedure(TCLP) and sequential extraction methods were used to evaluate the efficiency. The results showed that four phosphate fertilizers all could effectively reduce soil TCLP extractable Cd concentrations with the stabilization efficiency as MPP >DAP >SSP >TCP. The most effective dose with greatest Cd reduction was 4:1 of P:Cd ratio, the most reduction was 49%; Additions of all tested phosphate fertilizers can greatly improve the soil available phosphorus concentration with the concentration as MPP >DAP >SSP >TCP at the same level of P, TCLP extractable Cd concentration were significantly negatively correlated with soil available phosphorus concentration(R=-0.903^**); The decline of exchangeable Cd concentrations in DAP, MPP, SSP, and TCP treated soils was respectively 23.75%, 39.06%, 16.60% and 18.36%, but increased the Cd in WSA, OX, Fe-Mn-OM and RES. It indicates that Cd in soil can be adsorbed by phosphate fertilizers, reducing the bioavailability of Cd.
