英文摘要	Purpose Sustaining crop yield and decreasing the environmental risk of phosphorus (P) loss are key challenges for P fertilization management, which is helpful for achieving the goals for agriculture sustainable development. The effects of the long-term application of different organic amendments on P loss through surface runoff and leaching on sloping croplands have not been studied until now. Materials and methods We simultaneously measured the P loss based on a long-term fertilization experiment using a lysimeter (8 x 4 m(2)) with four treatments: control (no fertilizer; CK), mineral fertilizer (MF), mineral fertilizer combined with swine manure (MFSM), and mineral fertilizer combined with crop straw (MFCS). Results and discussion Annual P loss loads through surface runoff and leaching in the MF treatment were 90.3 +/- 29.4 and 39.2 +/- 13.2 mg m(-2), respectively. The quantitative relationship between soil P surplus and total P loss load was described by a positive linear function, which suggested that a total P loss of approximately 2.9 kg ha(-1) occurred with each 100 kg ha(-1) of P surplus. P recovery efficiencies in the MFSM and MFCS treatments increased obviously by 24.0% and 34.5%, whereas soil P surplus decreased by 10.5% and 62.4%, respectively. Overall, the yield-scaled total P losses for the MFSM and MFCS treatments decreased significantly by 71% and 200%, respectively, compared with the MF treatment (0.12 +/- 0.04 kg t(-1)). Conclusions Long-term organic amendment application, especially for crop straw, effectively decreased P surplus and P loss, thereby increasing P efficiency. We recommend the combined application of mineral fertilizer with crop straw as a sustainable agronomic P management practice to achieve sustainable goals for development of the United Nations and the land degradation neutrality challenge.
