쌀 공급과잉이 사회적 문제가 되면서 논에 타작물 재배를 위한 논의 다각적 활용 시스템 구축이 매우 중요해지고 있다. 정부는 이러한 논의 다각적 활용을 위해 2020년에 우리나라 최초의 농지범용화 시범사업 지구를 선정하였다. 전북 김제시 옥성지구는 농지범용화 시범사업 지구로 선정되어 용·배수로 정비가 실시되었다. 따라서 본 연구에서는 전북 김제시 옥성지구 용배수로 정비의 효과를 살펴보기 위해 시범사업 전후의 주요 영농여건 변화 실태를 살펴보았다. 이를 위해 본 연구에서는 농업경영체 DB, 흙토람 등을 이용해 옥성지구 일대 수혜 필지와 비수혜 필지를 추출하고, 각 필지별 실제 경작자 명단을 작성 후 1:1 면담 조사를 실시하였다. 옥성지구 농지범용화 시범사업 면적은 총 50.4ha인데, 169개 필지로 구성되었다. 이 중에서 129개 필지의 총 69명의 경작자 명단이 작성되었다. 그리고 본 연구의 조사에 총 30명이 참여했고, 이 가운데 수혜구역과 비수혜구역의 논을 동시에 경작하고 있는 9농가를 대상으로 논의 다각적 활용을 위한 용·배수 정비 전후의 성과를 조사하여 분석하였다. 첫째, 9농가는 모두 논콩을 재배하고 있다. 이들의 평균 논콩 재배면적은 2020년 1.76ha에서 2021년에는 2.22ha로 증가했다. 그리고 논콩 10a 당 생산량을 살펴보면, 2020년 355.8kg/10a에서 2021년에는 567.2kg/10a로 사업 전후 논콩 단수가 211.4kg/10a 증가했다. 평균 우리나라 전국 콩의 생산량이 203kg/10a, 전북 248kg/10a(2021년 기준)인데 반해 농지범용화 시범사업 지구의 논콩 생산성은 전국 평균보다 높은 것을 알 수 있다. 따라서 논의 다각적 활용을 위한 용배수로 정비를 통해 평균 단수는 211.4kg/10a 증가하기 때문에, 용배수로 정비는 논타작물 생산성 향상에 기여하고 있는 것을 알 수 있다. 둘째, 논의 다각적 활용을 위한 용배수로 정비 이전에 평균 침수 시간은 24시간 이내였다. 이러한 침수로 인해 논콩 재배농가들은 대부분 논타작물 재배의 어려움을 겪었다. 하지만 용배수로 정비 후 평균 침수 시간은 3시간 이내로 단축되었다. 이러한 침수시간 단축은 논콩 생산비 절감으로 이어져 용배수로 정비 후 시범사업 수혜 농가들의 논콩 직접생산비는 10a당 210,200원으로 전년 대비 34,250원/10a 감소하였다.

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.

The food self-sufficiency rate of agricultural products in Korea, excluding rice, is around 20%, and the government is promoting various policies including a Multiple-Purpose Utilization of Paddy Fields project, to increase the self-sufficiency rate of major grains. The project for Multiple-Purpose Utilization of Paddy Fields is being promoted as a part of a program to create farmland infrastructure to facilitate the cultivation of crops other than rice in rice paddies, and pilot projects were started in four regions in 2020. The purpose of this study is to analyze the economic effects of the pilot project for Multiple-Purpose Utilization of Paddy Fields, and to propose policies to increase the effectiveness of the project. In order to analyze the economic effect, we estimated the change in farm income generated by switching from rice to other crops, and measured the effect of welfare change using the Equilibrium Displacement Model (EDM). As a result of the analysis, social welfare is expected to increase when the pilot project for Multiple-Purpose Utilization of Paddy Fields is implemented, and the income of the beneficiary farmers is also expected to improve compared to that of single-cropping when double-cropping is implemented. However, it was found that the economic feasibility of the project differs depending on the crops converted. Juksan-myeon, Gimje-si, which is an area where soybean production was successful, was analyzed from the viewpoint of increasing the economic feasibility of the pilot project. Their success factors were analyzed into four major factors: infrastructure, farming methods, education, and collaboration with local agricultural organizations. If such a success story can be utilized in the future project implementation process, it can contribute to the improvement of farm household income and national economic welfare.

It is necessary to prepare a stable production base in advance for a change in the global grain market, and it is required to prepare comprehensive countermeasures such as securing technical skills and cultivation technology. Therefore, Korea, which relies on imports of major grains other than rice, could be exposed to a food crisis at any time unless the self-sufficiency rate of grains is improved. In order to respond to this new food crisis, it is necessary to find ways to efficiently utilize rice fields to increase the domestic grain self-sufficiency rate. From this point of view, interest and demand for the generalization of farmland that can be used as paddy fields and returned to paddy fields are increasing, and related research is also being continuously performed. In order to select a multipurpose farmland project site, this study extracted farmland containing 10% or more purchased and stockpiled farmland through spatial analysis (buffer, dissolve, intersect, etc.), and finally presented areas subject to multipurpose farmland projects. The target site for the multipurpose farmland project was finally selected by integrating data onto a point-by-point basis so that the current status of farmland purchased and stockpiled, Farm Manager Registration Records, and the Korean Soil Information System data (drainage classes, surface soil texture, field-suitability classification, etc.) can be used in combination. There are 175 areas where the multipurpose farmland is possible. Incheon 2, Gyeongbuk 40, Gangwon 2, Chungbuk 7, Chungnam 48, Jeonbuk 34, Jeonnam 19, Gyeongbuk 15, Gyeongnam 8. Chungcheongnam-do has the most target site for the multipurpose farmland project, and Gangwon-do is the least. It is expected to contribute to new commercialization and business expansion by deriving business areas by identifying the scale of the farmland multipurpose farmland project using Farm Manger Registration Records and spatial data.
