Organic phosphorus strategy combining target crops and the environment to advance food production and reduce agricultural phosphorus loss
Recycling organic phosphorus (P) sources may reduce dependence on synthetic P fertilizers in sustainable agriculture. However, the overall lack of understanding of the impact of organic P management practices on crop yields and the environment limits further optimization of organic P strategies. Herein, we first executed a global meta-analysis of over 860 paired observations to validate potential indicators for delineating risk zones for organic P fertilizer management. Then, a combination of machine learning tools and global datasets was used to further identify the risk zones for organic P management practices. Finally, an optimal organic P management strategy was developed considering the total P inputs, types of organic P sources, organic P proportions, and organic P management risk zones. Results indicated that the P activation coefficient (PAC) can be used as a potential indicator for delineating risk zones for organic P management. Hypothesis-oriented path analysis suggests that P inputs under low-soil-PAC conditions drive the preferential allocation of P to the occluded and moderately labile P pools and that organic P fertilizer application can positively affect labile P. P inputs under high-soil-PAC conditions have a more balanced effect on various P fractions of soil, and P inputs through organic fertilizers are primarily stored in the organic P pool. Current organic P management practices do not benefit food production in case of low-soil-PAC cropland and may increase the risk of P runoff in case of high-soil-PAC cropland. A combination of optimal organic P management with risk zones achieved a 13.3 % reduction in global P runoff and a 10.7 % increment in global food production compared with the use of synthetic P fertilizers alone. Our study provides a solution for enhancing the efficient use of organic P resources to create more productive, clean, and sustainable food production systems.
期刊介绍:
Agriculture, Ecosystems and Environment publishes scientific articles dealing with the interface between agroecosystems and the natural environment, specifically how agriculture influences the environment and how changes in that environment impact agroecosystems. Preference is given to papers from experimental and observational research at the field, system or landscape level, from studies that enhance our understanding of processes using data-based biophysical modelling, and papers that bridge scientific disciplines and integrate knowledge. All papers should be placed in an international or wide comparative context.
