By employing an artificial rain device, the effects of three rain intensities and three different fertilizer practices on soil and nutrient losses from sloping corn plots were studied using a complete randomized block experiment. Rain intensity was determined to be the main factor influencing the amount of surface runoff, total runoff, and sediment. No surface runoff or soil erosion occurred at low rain intensity. As rain intensity increased, the amount of surface runoff, total runoff, and sediment increased sharply, causing increased losses of P and K. Rain intensity had little influence on the amount of N lost. The amount of N lost was mainly influenced by fertilizer practices, showing a ranking of N loss from low to high respectively: balanced fertilization
