본 시험은 환경농업기술을 직접 농가에 파급시킬 목적으로 3년간($'96{\sim}'98$)수행하였던 연구결과를 토대로 1999년에 환경농업 시범마을인 남원시 대강면 방산리의 일반농가포장에서 수행한 결과이다. 계분 발효퇴비와 깻묵을 시용한 환경농업과 절충형농업 시험구의 벼 생육은 화학비료를 시용한 일반관행농업 시험구에 비하여 저조하였으며, 왕우렁이(Ampullarius insularus)를 이용한 잡초방제 효과는 제초제 2회(초 중기) 살포 효과보다 우수하였다. 목초액의 병해충 방제효과는 저조하였고, 또한 환경농업과 절충형농업 시험구의 정조수량은 일반관행농업 시험구에 비하여 $3{\sim}5%$ 감소 되였다. 수질은 환경농업과 절충형농업 시험구가 일반관행농업 시험구에 비하여 COD, $NO_3-N$, $SO_4^{2-}$, $Cl^-$등이 낮았으며, 물벼룩의 밀도는 높았다.
The aim of this study was to apply the new agricultural technique developed for three years($'96{\sim}'98$) by demonstration at an model farm of environmental agriculture located in Bangsan-ri, Dagang-myun, Namwon-city. Rice growth of environmental farming plot, which supplied with oil cake and compost fermented with chicken manure was reduced compared to that of conventional farming plot, which supplied with chemical fertilizers. Weed control by using of Ampullarius insularus in the rice paddy field was effective compared to that of control, which treated with chemical herbicide twice. The yield of rice was decreased of 35% in both environmental and eclectic farming polt compared to that of conventional farming plot. The water quality of environmental not and eclectic farming plot were good compared to conventional farming plot. Density of water flea was high in environmental and eclectic farming plot compared to that of the conventional farming plot.
