Nonpoint source pollution from cultivated croplands has often been associated with downstream water quality impairment in various watersheds. Given projected changes global climate patterns, this study contributes to the existing literature by elucidating impacts of projections on edge-of-field surface runoff and sediment nutrient losses. We apply a well-tested ecohydrological model, Agricultur...

Subsurface tile drainage from row-crop agricultural production systems has been identified as a major source of nitrate entering surface waters in the Mississippi River basin. Noncontrollable factors such as precipitation and mineralization of soil organic matter have a tremendous effect on drainage losses, nitrate concentrations, and nitrate loadings in subsurface drainage water. Cropping syst...
