The persistent environmental relevance of soil phosphorus sorption saturation. Current Pollution Reports. doi:10.1007/s40726-017-0058-4. Interpretive Summary: Controlling phosphorus loss from agricultural soils remains a priority water quality concern in much of the world. Dealing with soil phosphorus saturation, the build up of phosphorus in agricultural soils due to historical fertilizer management, is one of the most difficult problems to address. This review of the state of the science of soil phosphorus saturation highlights short and long-term approaches to its management. Technical Abstract: Controlling phosphorus (P) loss from agricultural soils remains a priority pollution concern in much of the world. Dissolved forms of P loss are amongst the most difficult to manage. The concept of soil P sorption saturation emerged from the Netherlands in the 1990s and has broad appeal as an environmental indicator and a management paradigm. For hydrologically active and connected soils, P sorption saturation is responsible for the stubborn problem of legacy P. Short and long-term mitigation options for elevated soil P sorption saturation do exist, all with trade-offs that require anything but business as usual. Ultimately, better incorporation of soil P sorption saturation into both crop fertility and environmental management programs is needed to promote the sustainable management of P in agricultural production systems. |
