Modeling the impact of nitrogen fertilizer application and tile drain configuration on nitrate leaching using SWAT

•NO3-N losses via tile drains decreased as depth decreased and spacing increased.•Reduction in N application rate yielded greatest reduction in NO3-N losses.•SWAT simulation results were consistent with those reported in the literature. Recently, the Soil and Water Assessment Tool (SWAT) was revised...
