Despite greater emphasis on holistic phosphorus (P) management, current nutrient advice delivered at farm-scale still focuses almost exclusively on agricultural production. This limits our ability to address national and international strategies for the delivery of multiple ecosystem services (ES). Currently there is no operational framework in place to manage P fertility for multiple ES delivery and to identify the costs of potentially sacrificing crop yield and/or quality. As soil P fertility plays a central role in ES delivery, we argue that soil test phosphorus (STP) concentration provides a suitable common unit of measure by which delivering multiple ES can be economically valued relative to maximum potential yield, in $ ha yr units. This value can then be traded, or payments made against one another, at spatio-temporal scales relevant for farmer and national policy objectives. Implementation of this framework into current P fertility management strategies would allow for the integration and interaction of different stakeholder interests in ES delivery on-farm and in the wider landscape. Further progress in biophysical modeling of soil P dynamics is needed to inform its adoption across diverse landscapes.
尽管人们更加重视整体磷（P）管理，但目前在农场层面提供的养分建议几乎仍然完全侧重于农业生产。这限制了我们实现提供多种生态系统服务（ES）的国家和国际战略的能力。目前，没有用于管理多种 ES 交付和确定潜在牺牲作物产量和/或质量的成本的操作框架。由于土壤 P 肥力在 ES 交付中起着核心作用，我们认为土壤测试磷（STP）浓度提供了一个合适的通用度量单位，可用于相对于最大潜在产量，以$ ha yr 为单位对提供多种 ES 进行经济价值评估。然后可以在与农民和国家政策目标相关的时空尺度上进行交易或相互支付。将该框架纳入当前的 P 肥力管理策略中，可以允许在农场和更广泛的景观中整合和互动不同利益相关者在 ES 交付方面的利益。需要进一步推进土壤 P 动态的生物物理建模，以在不同的景观中推广其应用。
