Characteristics of Nitrogen and Phosphorous Loadings from a Paddy Field Area
광역논에서의 질소와 인의 오염부하량 특성
Abstract
The inflow and outflow loads of T-N and T-P from a paddy field area during the irrigation period were investigated. For the concentration of T-N and T-P, surface water in paddies showed highest among irrigation water, drainage water and percolation water. For T-N, the average concentration of drainage water is higher than that of irrigation water before middle of June but is lower since. It is shown that the L(load)-Q (discharge) equation of T-N has high correlation for irrigation water, but the L-Q equation of T-P has high correlation for drainage water.
