Serious soil erosion on slope land of the Loess Plateau results in a great deal of nitrogen loss and restricts local agriculture greatly.In this study,simulated precipitation experiment was conducted to investigate the relationship between runoff and nitrogen loss on slope land.Runoff and sediment were sampled during rainfall and soil profile samples were collected 16 hours after precipitation.For all the samples,nitrate and ammonium were determined.The results showed that both nitrate and ammonium concentr...
