가축분뇨를 이용한 제주농업 발전방안에 관한 연구

Abstract

As examined above, this thesis analyzed the trends, regional specificity and disposal conditions of livestock excretions of Jeju agriculture on the assumption that the cultivation of Jeju-styled natural circulation farming, which can implement Eco-paradigm for the development of Jeju agriculture in the matrix of Eco-friendly environment, high-efficiency, and natural circulation, would be required, for strengthening the international competitiveness of Jeju agriculture. The summarizations of the results, obtained in this study, are as follows: First, the trends of Jeju agriculture demonstrate that the agricultural population of Jeju special self-governing province was 3.3 times higher than other areas. In addition, while citrus income increased by fulfilling the growth of scale along with the economic growth, the income of food crops and special crops (or industrial crops) showed a tendency of decline. In terms of the livestock industry, it reveals that gross income was on the increase because the number of farms decreased and hog population increased. Second, the generated amount of major livestock excretions in current Jeju was 1,266 tons per year. To treat the entire quantity of livestock excretions on the land, a wide range of policies have been established and enforced, and diverse attempts have been made for the Eco-friendly agriculture and natural circulation rather than simple disposal or discharge. Meanwhile, there are technical difficulties and needs for the formulary of fertilization. Third, the analysis results of the location reveal that the specialization of various crops was intended, but it had a tendency of weakening as a result of imported products and economic opening. However, crops that have specificity include malting barley, beans, watermelon, melon, strawberry, carrot, garlic, leeks, and onions. Even though tangerine, which is representative of Jeju province, showed a high specificity, its price can be a problem for the time being if alternative crops do not appear due to the excessive production. In view of the comprehensive analysis, which has been conducted so far, we can draw the conclusion that the agriculture of Jeju Special Self-Governing Province is put in considerable difficulty in establishing unified policy direction for the agricultural development due to various factors such as the changes in the international and domestic conditions which are inclusive of the negotiations of the Uruguay Round, WTO, DDA, and FTA, and problems in the agriculture and stockbreeding industry. In addition, to dispose of livestock excretions, inevitably generated, based on the methods such as purified water discharge can be served as an obstacle in the Jeju livestock industry due to the disposal costs. To manage livestock manure effectively, tentatively named "Livestock environmental management center" needs to be established and administrative department should do integrated management. In this regard, this thesis suggests that the operating systems of the optimum disposal in livestock excretions should be established through the revitalization of environmentally-friendly agriculture and branding crops by fertilizing in a timely manner through the investigation into the supply and the demand amount of fertilizers in agriculture farmhouses and adjustment of inflow in livestock excretions. In addition, Jeju needs to raise the weight of agriculture in Jeju economy as well as the coexistence of agriculture farmhouses and stockbreeding farmhouses by making livestock excretions into resources, in which the reduction of agricultural production cost is absolutely required to break through the problematic situation at home and abroad.
