  • Purpose: This study focuses on exploring ways to improve the distribution method of shrimp farming so that it is eco-friendly and increases the distribution of shrimp. Research design, data and methodology: The experimental device installed in a biofloc shrimp culture in one area tested 10 times. Complex odor, concentration of H2S, water quality improvement effected by decomposition of organic substances, and degree of microbial activation measured. The data of the experimental results verified using the T-test technique, and the p value was determined based on the significance probability of 0.05. Results: This experimental device was effective in reducing odor and hydrogen sulfide in shrimp farms. With the improvement of water quality, dissolved oxygen increased due to the microbubble and cavitation action of air ejector and ultrasonic waves. In addition, the cultured microorganisms in the cultured water treated by the experimental device were remarkably proliferated compared to the raw water. Conclusions: The biofloc distribution method has a significant effect on improving water quality and reducing odor substances and will become a new eco-friendly and efficient distribution method for shrimp farming in the future.

  • As the consumers' anxiety for food increases, the interest in food safety also increases. To satisfy the public requirement on food safety, the government is trying to set up a food safety standard by using regulations and certification systems. However, there is still difficulty in building up complex traceability systems for medicinal crops including ginseng due to the low participation of farming industries. The purpose of this empirical research is to draw factors that impede the GAP adoption of ginseng farms. By comparing the average attitude and intention to adopt the ginseng farms' depending on its characteristics through a two-tailed test, it was drawn that continuous farming education can positively influence the GAP adoption of the ginseng farms.

  • To address complex solutions to tack1e the cost rise with the increasing of the prices of crude oil, and to lower warming gas discharge in agricultural sector in line with the framework Convention on Climate Change, we need to net only develop the methods of simply reducing energy use ratio, but also effectively energize resources discharged in the course of agricultural production aimed at enabling repealed farming, and develop systems to reinvest such energy into agricultural production and apply them to actual farming. To that end, specifically, we need to reduce the energy cost in agricultural production, and produce and harness bio gas that makes it possible to stabilize the continued supply of energy. Thus, in this research, we seek to discuss energy use volume and warming gas discharge, and the characteristics of bio gas and its use methods alike, in agricultural sector, and thus present methods for environment-friendly and continual development in agriculture.

  • 황토유황합제 제조 5주 후 녹지 않은 잔재물을 제외하고 수용성 황토유황합제만 준비하였다. 황토유황합제 제조시 가성소당를 원래 양보다 25% 감량하여 황토유황합제의 pH를 pH 1 낮추었다. 현미식초(pH 2.8)을 이용하여 황토유황합제의 pH 수준을 pH 5.0에서11.0까지 현미식초(pH 2.8)를 이용하여 pH를 1씩 조절하였다. 황토유황합제 원액의 pH는 13으로 토마토에 살포하였을 때 신초와 꽃눈에 약해를 주었다. pH가 조정된 0.05% 황토유황합제를 E. cichoracearum에 의해 흰가루병이 발생한 토마토에 7일간격으로 2회 살포하였다. pH가 조정된 황토유황합제를 1회 살포하고 7일 후 토마토의 흰가루병이 70~95% 방제되었다. 두 번째 살포 후 토마토 흰가루병이 확연하게 방제되었다. 결론적으로 pH를 조정한 황토유황합제는 토마토에 약해를 보이지 않으며, 유기농업에서 토마토 흰가루병 방제용 자재로 사용할 수 있을 것으로 생각한다.

  • The suitable area of forage crop field was calculated under the assumption that all of the liquied manure would be used to nutrient of crops at the Saemangeum crop-livestock complex. At first, Korean cattle and dairy cattle were selected and swine was excluded becausr of high pollution availability. When forage crop was calculated from nutrient amounts of manure of livestocks and standard applicable fertilizer quantity to the selected forage crops, 232ha (278ha including infrastructure part) was determined to be appropriate in case of 2500 heads of Korean cattle and 300 heads of dairy cattle were raised. From the result by that calculated ares (232ha) to forage crop feeding could be possible to the Korean cattle and dairy cattle feeding using TDN index, more than 217ha of forage crop fields would be satisfied nutritionally.

  • 농어촌에서 발생하는 폐기물을 소각하는 최적의 소각로의 필요성이 대두된다. 농어촌에서 발생하는 수분이 다량으로 함유된 음식물 쓰레기나 폐비닐 또는 어촌에서 사용하고 남은 폐 그물 등은 그 처리에 더 큰 어려움을 겪고 있다. 또한 농어촌 폐기물의 성상분석 결과 도시의 폐기물과 마찬가지로 고열량을 가지고 있기 때문에 그에 맞는 설계도 고려대상이 된다. 본 연구에서는 농어촌 폐기물을 A, B지역으로 나누어 물리 화학적 조성 및 발열량 등을 비교 분석하고, Lab Scale의 연소로를 이용하여 농어촌 폐기물의 유해가스 발생량에 대하여 각각 20회에 걸쳐 실험하였다. 특히 농어촌 지역 특성상 발생하기 쉬운 폐비닐, 폐 그물에 중점을 맞추어서 조사하였으며, 그에 따른 폐기물의 배출현황 및 시료를 채취하여 성분을 분석하였다. 연구결과 농어촌 폐기물 특성상 발생하기 쉬운 폐 그물 이나 폐비닐 등의 합성수지계의 폐기물로 인해 발열량이 도시와는 1,000~1,900kcal/kg 가량의 큰 차이를 보였다. 이를 효과적으로 소각하기 위해서는 열분해 소각방식이 가장 적합하다는 결론을 얻게 되었다.

  • In this study, chemical characteristics of groundwater around carcass burial areas and those in agricultural and livestock-farming complex areas in South Korea were monitored. Groundwater samples were collected from 166 wells around carcass burial sites and 466 wells around the agricultural areas where carcass burial sites are absent. The chemical parameters (pH, electrical conductivity, dissolved oxygen, oxidation reduction potential, $NO_3$-N, $NH_4$-N, and $Cl^-$) in carcass burial areas and agricultural areas were similar. The $NO_3$-N concentrations exhibited minimal seasonal fluctuations below $30mg\;L^{-1}$ in most of the wells, even in the wells located close to the carcass burial sites; and $Cl^-$ concentrations also showed similar patterns. The chemical characteristics of groundwater monitored in this study indicated that groundwater was widely contaminated by agricultural activities and livestock farming, but probably not by leachates derived from nearby carcass burial sites.

  • In recent years, Korean rice must compete with the rice of advanced countries under Doha Development Agenda(DDA) and free Trade Agreement(FTA). Therefore we should find more active and positive solution in rice industry according to the inncreasing power of international pressure. Increasing rice production was the most important policy during the past food-deficient days, but recently, with overproduction of rice, various circulation system by the brand(price)-differentiation should be settled in a recent market of Korea. Nowadays, some advanced rice farmers and Rice Processing Complex(RPC) managers developed new brands of rice with high-quality, adding healthy materials and environment-friendly farming methods. Therefore, the future strategy of making a new brand rice should be planned including selection of rice variety, cultural and post-harvest techniques, circulation and processing methods to compete against foreign rice. And environment-friendly farming is also recommendable for food safety and differentiate from imported rice. For the purpose of successful brand-rice, the following points might be considered. Firstly, selection of good quality rice and continual development of good variety must be conducted for the differentiation of Korean rice from foreign rice. Secondly, a special contract between producer and consumer with functional-rice, organic filming-rice, specific-rice will be recommendable. Thirdly, improvement of post-harvest management and milling system are necessary for the production of differentiated-rice. Fortunately, standard of inspection, rules of description for brand-rice must be developed by a more scientific examination in order to settlement of trust for consumer. Finally, provincial or regional-representative brand rice must be settled and conducted for the development of agreement market system between producer and consumer.
