With increasing global concern that intensively synthetic chemical based farming systems accelerated the decline in environmental quality, the sustainability of modern agriculture became the subject of great concern. It is well known that the movement of Community Supported Agriculture(CSA) has been contributed significantly to the development of organic agriculture in USA and Japan.
It was supposed that CSA could be one of the best way to promote the movement of organic agriculture since there is little reliability on the organically grown food by consumer. In this paper it was focussed to study the movement of CSA in USA and Europe in order to provide an idea for establishment and movement of CSA in Korea to support the organic agriculture. In a CSA system, the farmer grows food for a group of shareholders who pledge to buy a portion of the farm"s crop that season. This arrangement gives growers up front cash to finance their operation and higher prices for produce, since the middleman has been eliminated. For most shareholder for CSA saving money is a secondary consideration, but fresh safe products and environmentally sound farming system. People become shareholder of CSA since they expect an organic farming which can；① protect the environment, minimize pollution, promote health, ② replenish and maintain long term soil fertility by providing optimal conditions for soil biological activity, ③ maintain diversity within the farming system and its surroundings and protect plant and wildlife habit, ④ recycle materials and resources to the greatest extent possible within the farm and its surrounding community, ⑤ maintain the integrity of organic food and processed products through each step of the process from planting to consumption, ⑥ develop and adopt new technologies with consideration for their long range social and ecological impact.
In all CSAs, the farmer develops a crop plan and a budget, which details costs for a growing season, including fair wages for the farmers. Experienced Information on increasing shareholder retention, the future of CSA, and getting started such as ideas for ongoing marketing, printed materials that set realistic expectations, working members, production, pick up and delivery, setting prices, and receiving feedback were also briefly introduced.

To clarify the proper and safe duration of maturation periods for sawdust pig manure composts, leaf lettuces were applied with pig manure composts fermented for 15, 30, 45, 60, 75 days and 1 year (control) and cultivated in a plastic house with or without additional PE film tunnel. The changes in physiochemical properties of soil and leaf lettuce growth were measured. Shorter duration of maturation periods enhanced the generation of NH₃ gas from the composts and resulted in significant decrease in seed germination, growth and yield of leaf lettuce. Under with and without PE tunnel conditions the concentration of NH₃ from compost over 3.8 and 2.1 ㎎/100g composts, respectively induced growth reduction. In proportion to the increase of maturation duration saw dust containing pig manure exhibited decrease in C/N ratio, NH₄⁺ N, NH₄⁺/NO₃ ratio but increase in NO₃ N contents. In case of applying pig manure compost without PE film tunnel condition the minimum maturation period of pig manure composts for safe leaf growth was 60 days, while minimum 75 days of maturation was required when applied with PE film tunnel.

This study was conducted to investigate the effects of microbial fertilizers on the yield of altari radish, chemical components of plant and soil, and the microbial floras. Six microbial fertilizers, MPK+Husk+Palma, Husk+Palma, MPK+Compost, Compost, Bio livestock cattle system (BLCS) cattle dropping, and Tomi, were used in this experiment. The yield of altari radish was increased in treatments of all microbial fertilizers. The concentration of all chemical components in plant were not significantly different. Whereas the amount of P₂O₅ in soil was increased in Compost treatment, the other components were not significantly different compared with control. The total bacteria and bacilli in soil were increased in Tomi, Husk+Palma, and MPK+ Husk+Palma treatments, and actinomycete and fungi were increased in Tomi treatment.

This experiment was carried out to investigate the effects of application levels of nightsoil sludge compost(NSC) in 3 and 4 cuttings per annum on the dry matter yields and nutritive value of orchardgrass(Dactylis glomerata L.). Annual nightsoil sludge compost(NSC) were applied at levels of 0, 10, 20, 40 and 80 ton ㏊ ¹, respectively. Relative yields of each cut to annual dry matter yield were 29.9%, 46.% and 23.2% for 1st cut, 2nd cut and 3rd cut in 3 cutting system, 23.7%, 29.3%, 34.0% and ¹3.0% for 1st cut, 2nd cut, 3rd cut and 4th cut in 4 cutting system, respectively. Significantly higher dry matter yield of orchardgrass obtained were 8.11 ton ㏊ ¹ at level of 40 ton ㏊ ¹ yr ¹ in 3 cutting systems, ranges of 7.50~10.71 ton ㏊ ¹ at level of 10~80 ton ㏊ ¹ yr ¹ in 4 cutting systems than those of non application level of NSC, respectively(p＜0.05). The mean efficiency of dry matter production to application of NSC(㎏ DM/ton NSC) were 46 and 102 ㎏ in 3 and 4 cutting systems, respectively. Although th contents of crude protein(CP, %) of orchardgrass were significantly higher at the application levels of 10~80 ton ㏊ ¹ yr ¹ by NSC than those of the application levels at the 0 ton ㏊ ¹ yr ¹ in 3 and 4 cutting systems(p＜0.05), the contents of neutral detergent fiber(NDF, %) and acid detergent fiber(ADF, %) were lower in NSC plots than those at the non application plots of NSC. The contents of total digestible nutrient(TDN, %) and relative feed value(RFV) of orchardgrass were significantly increased with increase the application levels of NSC(p＜0.05).

An experiment was carried out to evaluate the effects of adding phytase on nutrient digestibility in growing pigs. Three barrow pigs averaging 28.5±3.1kg of body weight were allotted to three treatments by 3×3 latin square. Treatments included 1) corn soybean meal based control diet and 2) and 3) control diet with phytase 500 and 1,000 unit. There were no effects of treatments on dry matter and nitrogen digestibility (P>0.05). Ash, Ca and P digestibility in pigs fed diet with phytase were greater than those in pigs fed control diet(P＜0.05). An increased phosphorus intake was observed from pigs fed diet with treatments compared to that from pigs fed control diet. Pigs fed diet with adding phytase had improved P absorption compared to pigs fed control diet(P＜0.05). There was no significantly effect on fecal and urine excretion(P＜0.05). Ca intake was increased for pigs fed adding phytase compared to pigs fed control diet. No evident effect was observed on Ca fecal excretion among dietary treatments, however, urine excretion of pigs fed diet with treatments was decreased compared to pigs fed control diet. Cystine, isoleucine, tyrosine and phenylalanine digestibility of amino acid were greater for pigs fed diet with treatments than those for pigs fed control diet(P＜0.05). Asparagine, threonine, serine, methionine and leucine digestibility were improved for pigs fed with phytase 500 unit compared to pigs fed control diet. Lysine, histidine, arginine and other animo acids digestibility were higher for pigs fed diet with phytase than control diet, but there were no significant effects by the treatments(P>0.05). In conclusion, the results of the experiments suggest that phytase supplementation in the diets could be a very beneficial strategy in environmental aspects.

This study was conducted to investigate the effect of sewage sludge application on the growth of chinese cabbage and the changes of chemical properties of soil. The experiment were set up with two different place and cultivated from Feb. 10 to June. 20 of 2000. Treatments are 0, 1.25, 2.5, 5, 10 and 20㎏/3.3㎡ of sewage sludge applicated into the soil and recorded the growth characteristics. Chemical properties of soil were also analysed before and after treatment.
The application of the sewage sludge resulted in increasing the content of EC, cations exchange capacity, available phosphate and organic matter. And increased the growth characteristics in terms of the number of leaves, leaf area, fresh and dry weight regardless of crops experiments. Optimum amount of the sewage sludge depended on chemical properties of soil used.
This results demonstrated that application of sewage sludge in the soil attribute to have play an important both improving soil chemical properties and promoting the crop growth. As lowering the soil pH(pH 6) heavy metal content increased compared with higher pH(pH 7). Feasibility was recognized in the application of sewage sludge as a fertilizer for the growth of chinese cabbage. Detrimental effects such as heavy metal in the soil and crop followed by the application of sewage sludge was not observed.
