Interpretive Summary: Soil health and P loss is not often discussed in the producer and research community alike. We wanted to write a commentary discussion trade-offs commonly associated with soil health management practices and P loss. While not all best management practices can mitigate N and P losses, this is often not clear in materials available from government and university organizations. We hope that future materials and research can clearly discuss these trade-offs.
Technical Abstract: Soil health practices and their associated benefits attract considerable attention in the agronomic and research worlds. While soil health is a broad term with variable definitions, it has practically been tied to: improving soil condition through reducing or eliminating tillage and increasing the amount of soil cover and living roots primarily via cover crops. In this paper, we briefly review soil health ‘friendly’ practices such as conservation tillage and cover crops and their impact on phosphorus (P) loss. After reviewing current peer-reviewed publications, we cannot substantiate reductions in P losses due these practices. We believe that recommendations made to agricultural communities should discuss trade-offs associated with these practices, emphasizing that they may not effectively reduce all nutrient loading from agricultural fields.
