상수원 보호지역내 하상충적토, 사력질의 벼 재배 논에서 표준시비, 농가관행시비, 우분, 우분퇴비, 볏짚퇴비+화학비료감비, 볏짚환원+표준시비 그리고 무비구의 7 처리를 하여 벼 재배 과정 동안 비료성분의 지하 용탈특성을 조사, 분석한 결과는 다음과 같다. 관정수중의 질산태 질소의 농도는 인근 농경지로부터 시비질소의 유입이 시작된 이앙일에는
To establish the best rice cultivating system in the aspects of environment-loving agriculture, the amounts and patterns of nitrogen leached in the paddy soil were investigated with 7 treatments; Recommendation(R), Farmer's usual practice(FUP), Straw compost+chemical fertilizers reduced(SCF), Fresh straw+recommendation(FSC), Fresh cow manure(FCM), Cow manure compost(CMC), and no fertilization as Control(C). And SCF, FCM and CMC were applied with same amounts of total nitrogen to R. The infiltrated water samples were collected in ceramic porous cups which were buried at 60cm depth from the top. Concentrations of nitrate-N in irrigated water were
