Runoff loading of nutrients in conventional and environmental paddy plots

We investigated concentrations and loads of nutrients in the paddy plots with conventional and environmental paddy plots in Chungbuk. Different fertilizers for basa dressing were applied to two paddy plots. There were not significantly different concentrations between two experimental paddy plots because almost same amount of fertilizers were applied to two plots. For drainage water during rainy days mean T-N concentration was lower, but mean T-P concentration was almost identical compared with respective values in flooded water.
