Transforming soil phosphorus fertility management strategies to support the delivery of multiple ecosystem services from agricultural systems. Science of the Total Environment. 649:90-98. https://doi.org/10.1016/j.scitotenv.2018.08.272.
Interpretive Summary: In recent years, practitioners have emphasized holistic phosphorus management, however current nutrient management advice delivered to farmers has focused almost exclusively on agronomic productivity. This limits our ability to address national and international strategies for delivery of multiple ecosystem services (such as protecting water quality or encouraging biodiversity), because there is currently no mechanism to quantify and value the delivery of ecosystem services. In this paper, we make the case that soil test phosphorus concentrations could be used as a proxy, whereby different ecosystem services can be evaluated and traded against each other at spatial scales relevant for farmer and national policy objectives. The establishment of such a mechanism allows for the integration and interaction of different stakeholder interests in ecosystem service delivers on farms and in the wider landscape.
Technical Abstract: Despite greater emphasis on holistic phosphorus (P) management, current nutrient management advice delivered at farm scale focuses almost exclusively on agricultural production. This limits our ability to address national and international strategies for delivery of multiple ecosystem services (ES), because there is currently no mechanism to quantify and value ES delivery, and trade-off the costs of potentially sacrificing crop yield. As soil P fertility has a central role in ES delivery, we argue that soil test phosphorus (STP) concentration could be used as a proxy by which different ES can be assessed and traded against one another at spatial scales relevant for farmer and national policy objectives. The establishment of such a mechanism allows for the integration and interaction of different stakeholder interests in ES delivery on farms and in the wider landscape.
