Description

Transport of nitrogen (N) and phosphorus (P) in various forms to water resources can cause water quality concerns relative to drinking water and aquatic life that has to live in those waters receiving agricultural drainage. Of particular concern is the fate of nutrients applied as fertilizer and/or animal manures, and their potential transport with runoff water, eroded soil/sediment, and leaching water. In order to reduce or control nutrient transport/losses, an understanding of the factors that affect losses (chemical, hydrologic, and management) is needed. An ongoing monitoring study of the Upper Maquoketa River in northeast Iowa is providing watershed-scale information on nutrient fate and transport and is the basis for this paper.
