The primary objective of most agricultural operations including those at the Strawberry Creek Watershed is to maximize crop yield. This often requires the input of additional nutrients to enhance soil fertility, and installation of artificial subsurface drainage to curtail water-logging of soils with very low hydraulic conductivity. However, the combination of additional nutrients and subsurface drainage often leads to a disruption of the existing hydrochemical regime. Excess nitrate and phosphorus export to surface water bodies may yield negative environmental impacts, including the eutrophication of downstream areas. To address this issue, a modeling technique was deployed to quantify and assess these …
