Nitrogen (N) and phosphorus (P) losses were determined in the sediment and water components of surface runoff from fertilized and unfertilized plots on a Barnes loam soil located in west‐central Minnesota. Simulated rainfall was used to cause surface runoff from small fallow plots that received uniform amounts of N and P but that had a different placement of the broadcast fertilizer. Deep incorporation of the fertilizer by plowing down (and subsequent disking) caused N and P losses about equal to those in surface runoff from unfertilized plots. The highest nutrient losses occurred when the fertilizer was broadcast on a disked surface.
