Abstract

Abstract : 2019 will be the 350th anniversary of the discovery of phosphorus (P) by the alchemist Henning Brandt. This perspective traces the historical threads that P has weaved through the fabric of our society and identifies challenges to improve P stewardship in the future and for our future. A century after Brandt's discovery, P was identified in bone ash, which became the primary source of P until guano and ultimately rock P was mined to provide the various mineral formulations used today. Owing to limited supplies, a strategic shift in resource management ethics—from exploiting to conserving P resources—is needed. In agriculture, remedial strategies should consider when conservation practices can transition from P sinks to sources; however, a broader, long‐term strategy for P stewardship is needed. This must include R educing P loss in food and other wastes, R ecovering P from waste streams, R eusing P generated beneficial by‐products, and R estructuring production systems. A key action to enact such changes will be collaboration across all sectors of society and the supply chain, from field to fork and beyond. As this will likely increase the cost of food, fiber, and feed production, it will require an innovative mix of public and private initiatives. Core Ideas: 2019, 350 years since phosphorus discovery, is a good time to envision our next 350 years. P weaves a complex web through the fabric of agricultural and societal management. We face a conundrum of coincident consequences of P deficiencies and excesses. Collaboration among the supply chain must engage in sustainable P stewardship. P stewardship 4Rs must be broadened to R educe, R ecover, R euse, and R estructure.
