In order to explore the difference of phosphorus accumulation and loss risk of different organic fertilizers in the process of reclaiming the soil in the mining area. In this experiment, the reclaimed soil of coal mining collapse in Xiaoyi City, Shanxi Province was taken as the research object, and the effect of different organic fertilizers, including poultry manure, swine manure,cow manure and chemical fertilizer, under 4 P levels (0, 25, 50, 100 kg/hm²) after 4 years in reclaimed soil of mining area on total phosphorus, Olsen-P, Mehlich3-P, CaCl₂-P, and degree of phosphorus saturation (DPS) and the relationship among them were studied. The results showed that:(1) The application of organic fertilizers increased the phosphorus content in the soil, and the greater the amount of phosphorus applied, the more obvious the impact on the phosphorus content, especially the total phosphorus, Olsen-P, Mehilic3-P in the soil, and CaCl₂-P increased; Compared with non-phosphorus treatment and chemical fertilizer, the application of organic fertilizers increased the surface layer (0-20 cm) soil degree of phosphorus saturation (DPS); In general, the effects of different fertilization treatments on the soil phosphorus content showed that poultry manure ≥ swine manure>cow manure>chemical fertilizer. (2) There was a significant linear correlation between the soil Olsen-P and Mehlich3-P, Olsen-P and CaCl₂-P, Mehlich3-P and CaCl₂-P in each fertilization treatment. (3) Compared with swine manure, cow manure and chemical fertilizer treatment, poultry manure treatment had the greatest impact on the risk of phosphorus loss in reclaimed soil. When DPS ≥ 39.31%, Olsen-P ≥ 26.24 mg/kg and Mehlich3-P ≥ 49.06 mg/kg, the content of CaCl₂-P in soil increased rapidly. Therefore, the above indexs could be used as the critical value of phosphorus loss in reclaimed soil of mining area. If these values exceed, the risk of soil P loss would increase. We need to be vigilant about the pollution of surface and underground water.
