Abstract Two amendments, calcium-magnesium phosphate fertilizer (CaMgP) and calcium-aluminum hydrotalcite (CAH), were selected to immobilize cadmium (Cd) in a Cd-contaminated paddy field in the South Jiangsu Province. The Cd-immobilization efficiency and the characteristics of phosphorus (P) accumulation and movement in water-soil environment caused by using P-containing amendments were studied. The results showed that the application of two amendments both effectively reduced the availability of Cd in the soil. The concentrations of available Cd in all treatments slowly decreased over time and reached the lowest level at the time of 16 weeks from amendments application. Compared to the initial soils, the immobilization efficiency of Cd for different treatments were sorted in descending order as 1500kg/hm² CaMgP (54.5%) > 6000kg/hm²CAH (50.3%) > 750kg/hm² CaMgP (46.9%). A significant and negative relationship between soil pH and available Cd at different stages of treatments was also found. The application of CaMgP as an amendment accelerated the accumulation of P in the soil. In addition, the total P and soluble P concentrations in the leakage water at 60~90cm depth tended to increase significantly with the increasing of CaMgP application.
