Variable impacts of contemporary versus legacy agricultural phosphorus on US river water quality
Sarah M. Stackpoole, Edward G. Stets, Lori A. Sprague
2019, PNAS (116) 20562-20567
Phosphorus (P) fertilizer has contributed to the eutrophication of freshwater ecosystems. Watershed-based conservation programs aiming to reduce external P loading to surface waters have not resulted in significant water-quality improvements. One factor that can help explain the lack of water-quality response is remobilization of accumulated legacy (historical) P within the...
