Presently the concept of organic farming has not simply technical categories such as no agricul-tural chemicals and no chemical fertilizer but can be also extended to the categories of economics, food nutrition, environmental and philosophical aspects. Accordingly, in order to understand cor-rectly organic farming, it is necessary to look into the concept including these extended aspects. So the production and consumption activities of organic farming products are largely based on the fundamental philosophy of organic farming. That is, all the life that is included in an ecosystem has to live in symbiosis, which is based on life circulation principle. And if this circultaion system is destroyed, human life may be threatended. Farmers who produce organic farming prducts(organic farmer) receive price higher than general farmers. This study shows the gap of 46.9% in two products. Also, since the price of organic farming products is fluctuated less relatively, Organic farming pruducts can be competed against imported agricultural products in terms of food safety. And organic farming should be managed by crop rotation and composite farm management upon which the principle of material circulation is worked. This composite management is devided into 2 classes, which are individually livestock-have-composite management and regional composite management. These management method means that organic materials are crucial to maintain the structure and fertility and these organic materials are easily obtained from animal as by-products.

EFA production systems have through necessity resulted in the development of innovative practices for weed, pest and diseases control, for example, using ducks and snails for weed control in paddy fields. These practices began to be introduced in the early 1990's and the techniques have become more popular and have been adapted to suit regional conditions. In this study, the production practices, productivity and economic performances of organic and non-chemical rice farming adopting ducks and snails for weed control were compared. In the production practices, Korean organic and non-chemical farming seem to have several concerns in terms of sustainability. It comprises lack of resistant variety use and rotational cropping system as well as high dependency upon external inputs such as organic fertilizer and farming materials for pest control. The production level of organic farming is approximately similar level but 20% higher income than non-chemical farming, while, when it was compared with conventional farming organic farming showed 20% lower productivity but 20% higher income. Organic farming shows 15% to 18% higher profits than non-chemical farming as the snail-using organic farming tends to have higher income and lower input costs than duck-using organic farming. This may encourage more farmers to convert to organic production using these techniques than simply non-chemical farming in the future. This organic conversion could be more promoted by policy intervention. However, it may result in increased supply and therefore decreased prices for organic rice in the long term unless further market demand occurs. Balanced policy measures considering production as well as marketing and consumption are urgently required for the sustainable development of organic farming.

The objective of this paper is to analyze management performance of organic farming management organizations in the large-scale environment-friendly agricultural districts, focusing on cases of organic farming organizations in Chungnam Asan city and Gyeongnam Sancheong-gun which are leading regions in Korean organic agriculture. The management performance in Asan Organic Farming Organization showed that ratio of operating gain to revenue in 2008~2009 increased by 1.2% point compared to in 2006~2007. The management performance in Sancheong Organic Farming Organization showed revenue gain by KRW 2 million in 2009 whereas it suffered a loss by KRW 24 million in 2008. The management performances implied that the amount of financial performance was not yet large and would be a symbol for soundly developing organic farming organization. This paper suggested that network system, recycling agriculture, and the enlargement of processing industry would be very useful to maximize synergy effect in organic farming organizations in a large-scale environment-friendly agricultural districts.

Recently, agriculture in Korea is seriously depressed by economic globalization and trade liberalization because of low competitive power. Organic farming, which is favorable for small scale agriculture, is expected to be one of alternatives to boost agricultural activities in Korea. Organic agriculture requires systemic developments of new technologies considering the complex biological interaction within the system in connection with high quality and safety standard. The National Institute of Agricultural Science & Technology(NIAST) has been worked on the series of organic farming technologies, including bio-pesticides, pheromone, natural enemies as well as the testings of materials used in organic farming. NIAST will concentrate on the technological development for compromising to the conflict between commodity-oriented and ecological harmony. Research on systemic land and water use, management of plant nutrition, pest and disease control, post-harvest would also be important targets. Integrated efforts among researchers, professors, administrators, farmers, private sectors, and extension workers are substantial for fast technology development and its dissemination. Development and use of these technologies will homely enlighten the Korean organic farming although it may require quite a time and endeavor.

In order to get some basic data to check the environmental sound function against soil and water pollution and the safe vegetable production by korean organic farming where an internationally recognized basic concepts of soil fertility management for organic farming is not practiced and only applying the organic fertilizer to maintain the soil fertility, the chemical characteristics of soils and $NO_{3}^{-}$ content of chinese cabbage and lettuce cultivated by the conventional farming, greenhouse cultivation and organic farming were investigated. The highest value of $NO_{3}^{-}$-N in 0~30cm subsoil among the three different farming systems was found in the subsoil of organic farming and it was 3.6 and 6.6 times higher than those of conventional farming in chinese cabbage and lettuce respectively. $P_2O_5$ accumulation in the rhizosphere by organic farming also showed the highest value. The accumulation of $NO_{3}^{-}$-N and $P_2O_5$ in organic farming soil were similar or even more higher to those of greenhouse cultivation. The $NO_{3}^{-}$ accumulation in the vegetable by organic farming reached 3224ppm for chinese cabbage and 2543ppm for lettuce, and it were 4.7 and 6.4 times higher than those by conventional farming. It was concluded that there is urgently necessary to introduce the main concepts of soil fertility management of the Basic Standard of IFOAM, EU regulation and FAO/WHO Codex Alimentarius on organic agriculture(draft) into korean organic agriculture for the operation of environmental sound system and the production of sate vegetable in terms of $NO_{3}^{-}$ content.

Since 1997, Korean Ministry of Knowledge Economy and Ministry of Environment have established data on some 400 basic raw and subsidiary materials and process like energy, petro-chemical, steel, cement, glass, paper, construction materials, transportation, recycling and disposal etc by initiating establishment of LCI database. Regarding agriculture, Rural Development Administration has conducted establishment of LCI database for major farm products like rice, barley, beans, cabbage and radish etc from 2009, and released that they would establish LCI database for 50 items until 2020 later on. The domestic LCI database for seeds, seedling, agrochemical, inorganic, fertilizer and organic fertilizer etc is only at initial stage of establishment, so overseas LCI databases are brought and being used. However, since the domestic and overseas natural environments differ, they fall behind in reliability. Therefore, this study has the purpose to select organic farming materials, survey the production process for various types of organic farming materials and establish LCI database for the effects of greenhouse gas emitted by each crop during the process. As for selecting methods, in this study organic farming materials were selected in the method of direct observation of material and bottom-up method a survey method with focus on the organic farming materials admitted into rice production. For the basic unit of carbon emission amount by the production of 1kg of organic farming material, the software PASS 4.1.1 developed by Korea Accreditation Board under Ministry of Knowledge Economy was used. The study had the goal to ultimately provide basic unit to calculate carbon emission amount in executing many institutions like goal management system and carbon performance display system etc in agricultural sector to be conducted later on. As a result, emission basic units per 1kg of production were calculated to be 0.04968kg-$CO_2$ for oystershells, 0.004692kg-$CO_2$ for expanded rice hull, and 1.029kg-$CO_2$ for bordeaux mixture liquid.

Most of European countries have certain support measures of small holder organic producers in their policy system but they need to be more positive with this issue. Recent EU regulations and any other governmental organic farming measures are hardly emphasising on small holders' issues except a few measures. In order to secure small producer organic farming, the extensive efforts are needed. Developing new logos and differential support system for small producer organic at every aspects from production, marketing and public procurement level will become more positive actions to take, for example.
