Pollutant concentrations in Experimental Paddy Plots with Different Fertilizer Application Rates
시비조건의 차이에 따른 시험군 논에서의 오염물질의 농도
Abstract
The effect of fertiltzer application on ponded and percolation water in rice paddy were investigated at the experimental plots during irrigation period. We laid out three experimental plots such as 150% Excessive, 100% Standard and 70% Reduced. The concentration of T-N and T-P in ponded water were increased rapidly after application. The concentration of T-N and COD in percolated water increased with fertilizer application rates, while T-P concentration were almost constant.
