BACKGROUND: To investigate mineralization characteristics of organic resources in the soil, five materials (rice straw, cow manure sawdust compost, microorganism compost, mixed oil-cake, and amino acid fertilizer) were treated according to the nitrogen content, and an indoor incubation experiment wa...

생태의 원칙은? | 유기농업에서는 생태적인 환경과 자원의 순환이라는 생태의 원칙에 따라 작물을 재배하고 관리하도록 하고 있다. 유기 농업도 경제적인 활동이라 수확량을 우선으로 작물을 재배할수 밖에 없는데, 작물의 수량을 높이기 위해서는 작물이 필요로 하는 만큼의 양분을 땅에 넣어주어야 한다. | |
유기자원의 사용목적은 무엇인가? | 유기자원의 사용목적은 토양에 탄소 및 질소 등 영양성분의 축적으로 작물생육을 도모하기 위함이다. 유기자원은 탄소 의 양에 따라 작물이 필요로 하는 질소의 함량도 달라진다. | |
지속가능하고 건강한 농업, 농촌사회를 만들기 위한 물질의 지역적 순환의 예시는? | 지속가능하고 건강한 농업, 농촌사회를 만들기 위해서는 물질의 지역적 순환이 필요하다. 경축순환 유기농업을 통해 양분의 순환 등 물질의 순환구조를 완성하는 자원순환형 농업모델(Yoon and Park, 2009)이 가능하며, 양분의 지역적 순환의 중심은 유기물이다(Yoon et al., 2009). 과거 퇴구비를 주 유기물원으로 사용하던 시대보다 화학비료가 국내 농업에 투입된 이후 국내농경지의 유기물함량은 90년대 중반부터 2000년대 초반까지 낮아지다가 현재는 일정비율을 유지하고 있다(Kim et al. |
