phosphorus ASU


Current human use of phosphorus (P) challenges the sustainability of the food system, as geological and geopolitical uncertainties threaten supplies of affordable fertilizer while runoff from cities and farms can cause damaging algal blooms in lakes and oceans.

To meet these challenges, accelerated innovation in P sustainability technologies and practices in the food system is needed.

The Sustainable P Initiative (SPI) stimulates these P solutions through our joint initiatives for research (P RCN) and implementation (SPA). The P RCN and SPA share four themes for P sustainability: P Recycling; P Efficiency in Food Production; P Demand: Population, Food Choice & BioEnergy; and P & Water Quality.
