초록

우리나라 정부는 논·밭 범용화 사업을 적극적으로 추진하고 있다. 그러나 범용 농지의 배수 불량을 해결하기 위한 암거배수 등의 기술이 필요하여 설치 및 관리 비용이 높아진다. 본 연구는 논 배수 불량과 관련된 문제를 해결하기 위한 코이어 폐배지를 활용하여 유망하고 지속 가능한 접근 방식을 제시할 수 있다. 콩을 논 토양 및 코이어 폐배지에서 두 재식 간격(80×20cm 및 60×20cm)으로 재배하였다. 공극률과 우수한 배수성을 특징으로 하는 코이어 배지를 재활용함으로써, 토양의 물리적 특성과 작물 생산성 및 품질을 모두 향상시키는 데 우수한 결과를 도출했다. PS 처리구와 비교하여 CS 처리구에서 수확량이 41.4% 증가하였고, 단백질 함량은 21.3% 증가하였다. 기존의 논의 범용 농지 전환을 위한 높은 초기투자비용 및 유지비용을 줄일 수 있는 해당 기술은 국내외 농가에게 높은 경제성과 환경 친화적인 범용 농지 재배 기술을 제공하고 범용 농지가 가지고 있는 배수 불량 문제를 해결하며 농업 폐기물 관리에 기여함으로써 다양한 사회적 솔루션을 제공할 수 있다. 이는 현대 농업에서 지속 가능한 농업과 진화하는 농업에 의거한 경종적 방법을 제시한다.

In recent years, the government has strongly promoted multi-purpose utilization of paddy field. However, poor drainage causes waterlogging stress in upland crops, requiring subsurface drainage technology, resulting in high installation and management costs. To address this issue, a low-cost and high-efficiency technique was developed that utilizes wasted coir substrates which have characteristics of high porosity and good drainage, for upland crop cultivation in paddy fields. Soybeans were grown in both paddy soil and wasted coir slab with two planting densities (80×20 cm and 60×20 cm). The results showed that the coir substrates had better performance than the paddy soil in terms of soil physical and chemical properties and the growth and yield of upland crops are improved. The treatments using wasted coir substrate showed a 41.4% increase in yield and a 21.3% increase in protein content compared to PS treatment. Our findings demonstrate that recycling waste coir substrates to grow upland crops is a positive cultivation strategy to solve some drainage problems in paddy fields. This approach offers a sustainable solution for upland crop production while also addressing the issue of waste management in agriculture.
