초록
김해평야의 6개 관개 수계별 및 시기별로 농업용수오염 및 벼의 무기성분 함량을 조사하고, 관개수에 의한 질소 공급량을 산출한 결과를 요약하면 다음과 같다. 1) 각 지점의 농업용수의 시기별 평균치는 pH 6.5-7.0, DO 0.6-7.7ppm, BOD4.4-63.5ppm, COD 7.3-73.9ppm,
Water pollution status of the irrigation water, inorganic nutrient contents of rice plant, relationship between water quality of irrigation water and inorganic nutrient contents of rice plant, and nitrogen supply by irrigation water at six sites of pumping stations in Kimhae plain were investigated. The results were as follows : 1. Average values of water components analyzed at all pumping stations were in the range of 6.5-7.0 pH, 0.6-7.7ppm DO, 4.4-63.5ppm BOD, 7.3-73.9ppm COD, 1.84-16.22ppm
