Global database of diffuse riverine nitrogen and phosphorus loads and yields

Abstract Human activities have increased the input of nitrogen and phosphorus into riverine systems. These inputs can increase algal growth that degrades aquatic ecosystems. We constructed a global database of diffuse loads (kg) and yields (kg ha−1 yr−1) of dissolved and total nitrogen and phosphoru...
