유기농업이란? | 유기농업은 근대농업에서 농업기술의 발달과 더불어 수반된 환경과 생태계의 파괴를 최소화하면서 안전한 농산물을 생산하고자 집약적 투입재료인 화학비료와 농약의 사용을 배제하고 돌려짓기, 그루갈이, 녹비작물 재배, 유기물 넣기, 저항성 품종 선택 및 유축순환 농법 등 현재까지 알려진 친환경적, 유기적인 기술을 활용하는 농업이라 할 수 있다 (Chang, 2000; Shon, 2001; Shon, 2002; Ulrich et al., 2004; Jung, 2005). | |
유기농업 재배에서 과다한 유기물 시용에 의한 양분 축적을 완화하기 위하여 외국에서 사용하는 방법은? | , 2006). 이러한 과다한 유기물 시용에 의한 양분 축적을 완화하기 위하여 추비용으로 유기액비의 활용이 대두되고 있으며 외국에서는 병원균의 억제와 토양 미생물상의 개선을 위하여 퇴비추출물 (Compost extract, compost tea)을 많이 활용하고 있다 (Weltzein, 1989; Kai et al, 1990; Elad and Shtienberg, 1994; Diver, 1998). 주로 유기액비에 대한 연구는 가축분뇨 액비의 제조특성 (Jung et al. | |
독일, 스위스 등 유럽국가와 미국, 캐나다에서 유기농업을 수행하기 위하여 사용하는 방법은? | , 2004; Jung, 2005). 우리나라의 유기농업은 주로 유기물 시용에 의존하여 지력 향상을 도모하고 있으나 독일, 스위스 등 유럽국가와 미국, 캐나다에서는 유기농업을 수행하기 위하여 기본적으로 녹비작물, 두과작물, 심근성 작물 재배 등의 윤작체계로 지력을 유지하고 적정한 퇴비 시용, 특히 가축사양에서 발생한 퇴비는 한정된 면적에 제한 적으로 사용하고 있다 (Shon, 2001; Shon, 2002; Ulrich et al., 2004; Lee et al. |
