Long-term trends in watershed nitrogen and phosphorus exports
Groffman, Peter

Abstract: The Baltimore Ecosystem Study has tracked trends in nitrate, total nitrogen, phosphate, total phosphorus, sulfate and chloride since 1998. Long- term trends in these constituents are driven by multiple factors include hydroclimatic variability, infrastructure improvements and changes in management. In this talk, I will summarize key trends, our understanding of the factors controlling these trends, and challenges in predicting future trajectories.
