Abstract
Controlling future phosphorus (P) loss will not be simple. The main nutrient “culprit” in freshwater contamination, P, becomes available only in its dissolved inorganic form in solution; and that solubility is also what can contaminate the environment if the P ends up in the wrong place. This article examines future P loss measures for agricultural systems. Beyond continued vigilance with regards to best management practices (BMPs), future mitigation tools include physical filters of P loss from crop fields, updating P soil‐test calibrations, stream buffers, cover crops, biologic products that may alter P availability, enzyme additives, and potential P recycling and trading markets.
