The objective of this paper is to apply choice experiment methods to estimate non-market value of organic farming and its policy implication. A preliminary survey shows that the attributes of organic farming are reduce environmental pollution, bio-diversity improvements, cultural diversity improvements and maintain local community, reduce green-house gas emissions, energy saving, landscape improvements and tax for organic farming improvement policy. Questionnaire was eight different choice sets presented to each respondent. Implicit values of the attributive levels of organic farming have been calculated into tax money costs per house. This paper compared the six feasible scenarios in terms of willingness to pay per year. This study is expected to contribute to government’s organic farming policies and quantitative information related to practice 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.

This study was carried out to investigate the effects of wormwood (Artemisia sp.) addition on the growth performance, nutrients utilization and abdominal fat deposition of broiler chickens. Two hundred twenty five and two-day old Arboracre strain male commercial broiler chicks were distributed to 5 treatments with wormwood supplementation levels; C(0%), T₁ (1%), T₂ (3%), T₃ (5%), and T₄ (10%) and with 3 replications each with 5 birds for five weeks. Body weight gain during the experiment was improved in T₁ (1723.0g) compared with that of T₃ (1557.7g) and T₄ (1450.7g) (P＜0.05). Feed intake was significantly (P＜0.05) increased as the levels of wormwood addition increased (C: 2653.8g, T₁: 2852.0, T₂: 2900.3, T₃: 2900.7g, T₄: 2954.7g). Feed conversion rate (feed/gain) was significantly (P＜0.05) increased as the levels of wormwood addition increased (C: 1.55, T₁: 1.66, T₂: 1.70, T₃: 1.86, T₄: 2.04). The days reaching to 2.0㎏ of body weight were expected to be 43.2 days in control, whereas those of group T₁ were reduced to 42.6 days by 0.6 day from control. Nutrient utilization and abdominal fat deposition in the experiment were significantly decreased (P＜0.05) and small intestine contents in the broilers was significantly increased (P＜0.05) as the levels of wormwood addition increased. Therefore, although there was no significant improvement for the performance of broiler chickens with the dietary supplementation of wormwood meal, less than 1% addition of wormwood to broiler diets might have beneficial for human health by reducing the abdominal fat deposition of the broiler chickens.

Sustainable farming systems have remarkably increased in Korea due to the increase of environmental concerns caused by the conventional systems. This study was performed on eight-year-old ‘Niitaka’ pear tree s to investigate the effects of different organic fertilizers on soil chemical and microbial properties and leaf and bud developments. Treatment and applications included 10 ㎏ of rice bran (RB), 10 ㎏ of coffee bran compost (CBC), 10 ㎏ of Chitin incubated compost (Micro keeper®, CIC), and 30 ㎏ of the mixture of the RB, CBC, and CIC (RCC). Control received 60 g of NPK (16-11-12) chemical fertilizer. The organic fertilizers increased organic matter, nutrient concentrations such as P, K, Ca, and Mg, and microbial biomass in soils compared to the control. RCC had the greatest specific leaf weight (SLW), and the other treatments did not have a significant difference for the SLW. Leaf P and K concentrations were different among the treatments, but they were not affected by the amounts of the soil nutrients. No differences were observed in the leaf Ca and Mg concentrations in the treatments. Organic fertilizers had greater chlorophyll contents than the control but had similar flower bud characteristics to the control.

Sweet persimmon, ‘Fuyu’, is the major cultivar for MA storage, but browning of blossom end part and fruit surface darkening occur during storage and decrease fruit qualities in fresh fruit market. Calcium (Ca) has a very important role in cell membrane and reduces Ca-related fruit disorder. Therefore, this study was conducted to investigate the effect of soluble Ca fertigation and foliar applications on soil chemical properties, root activity, and leaf nutrient status. Ca concentration in the soil was higher in both Ca fertigation (Ca-FG) and Ca+IBA fertigation (Ca+IBA) treatments than the other treatments, such as control (Cont), Ca foliar application (Ca-FA), and IBA fertigation (IBA). The increase in soil Ca improved soil pH. The Ca+IBA treatment increased root activity. Leaf Ca concentration was significantly increased by the CA-FA application, followed by Ca+IBA, and Ca-FG treatments.

This experiment was conducted to investigate the effects of dietary supplementation of oriental herb extracts (Alpha PlusⓇ (AP)+Dried Foxglove Powder (DFP)) on growth performance and proliferation of splenocytes in broiler chicken raised under low or high density stocking conditions. A total of 240 male broiler chicks were randomly divided into four treatment groups with three replicates composed of ten birds in low density stocking groups and thirty birds in high density stocking groups. The four treatment groups were as follows: C1 (low density without AP and DFP); T1 (low density with AP 0.2% and DFP 0.03%); C2 (high density without AP and DFP); T2 (high density with AP 0.2% and DFP 0.03%). The feed intake of the high density stocking group was significantly lower than that of low density stocking groups during overall experimental period (p＜0.05). The body weight of high density stocking groups was lower than that of low density stocking groups (p＜0.05). The decrease of feed intake and body weight gain in growing stage (7~25day) under the high density stocking condition seems to be recovered in final stage (26~34day). Meanwhile dietary supplementation of AP+DFP in low and high density stocking groups tended to have higher daily body weight gain than control groups. The proliferation of splenocytes in treatment groups was significantly higher than control groups (p＜0.05). In conclusion, the result of the present study suggested that the oriental herb extracts (AP+DFP) could be used as an alternative feed additive resources to improve growth performance and immune activity in broiler chickens.

This experiment was selected a β-glucan producing mushroom strain and developed industrial media, and used to β-glucan as an alternative for antibiotics in weaned pigs. Yields of mycelial biomass and extracellular β-glucan from Youngji (Ganoderma lucidum) mushroom was 8.52g/L and 4.49g/L respectively. Also, we prepared optimum formula for mushroom cultivations. A total of 144 pigs (8.6±0.9 ㎏ average body weight, weaned 20±3 days of age) were allotted to 4 different treatment groups and replicated 4 times with 8 pigs per replicate in randomized complete block design. Treatments were T1) NC (negative control, basal diet), T2) PC (positive control, basal diet+0.255% antibiotics), T3) NC+0.2% β-glucan and T4) PC+0.2% β-glucan. The T2 and T4 treatments were significantly higher in feed efficiency by antibiotics group (p＜0.05), however, there was no significant differences in terms of average daily gain (ADG) and average daily feed intake (ADFI) during phase Ⅰ(0~14 days). In phase Ⅱ(15~28 days), Pigs fed with antibiotics and β-glucan (T4) had greater ADG than other treatments (p＜0.05), while no differences were observed in ADFI and feed efficiency. During the whole experiment period, the ADG of T4 treatment was higher than other treatments. Pigs fed with β-glucan (T3 and T4) had greater diarrhea score and moisture content than other treatments (p＜0.05). Pigs fed with β-glucan (T3 and T4) had greater moisture content than other treatments (p＜0.05). However, there was no significant differences in diarrhea score and mortality of weaned pigs. There was marginal reductions in feed cost measured feed cost per weight gain used in antibiotics and β-glucan added diet during phaseⅠ. In the second phase, the treatment supplemented with antibiotics had a significantly lower feed cost per weight gain compared to the other treatments. The results from these experiments suggests that β-glucan is likely able to improve the growth performance, and reduce feed cost although they do not have similar effects like antibiotics in weaning pigs.

This study was conducted to determine effects of applying cattle slurry and mixed sowing with legumes such as hairy vetch or forage pea on productivity, feed values and organic stock carrying capacity of whole crop barley and rye as winter forage crops, and to obtain organic forages together with higher soil fertility. Experimental plots consisted of 7 treatments, which were non-fertilizer, chemical fertilizer (containing phosphate and potassium: P+K), chemical fertilizer (containing nitrogen, phosphate and potassium: N+P+K), organic fertilizer, cattle slurry, cattle slurry application (mixture with hairy vetch), and cattle slurry application (mixture with forage pea) plots. Each treatment was triplicates, and seven treatments were allocated in a completely randomized block design. For whole crop barley or its mixture crops, annual dry matter (DM), crude protein (CP), and total digestible nutrients (TDN) yields of N+P+K plots were significantly (P＜0.05) higher than other plots except for cattle slurry plots. The CP content of barley or its mixture crops was significantly higher for N+P+K plot (9.8%) and mixture plots with legumes (8.6~9.7%) than those of other treatments. As 450 ㎏ Hanwoo heifers were fed diets included 70% whole crop barley or 70% mixture crops with legumes, mixture plots are capable of raising average 1.7 to 1.8 heads/ha a year. For rye or its mixture crops, annual DM, CP, and TDN yields represented 6.9∼7.1, 0.5~0.6 and 4.3~4.4 ton/ha, respectively. The N+P+K plot contained 10.8% CP, which was higher (P＜0.05) than all other treatments. In case of 450 ㎏ Hanwoo heifers fed diets included 70% rye or 70% mixture crops with legumes, mixture plots can rear average 1.9 heads/ha a year. When it was considered based on crop yields and organic stock carrying capacity, applying cattle slurry to whole crop barley or rye had the comparable yields and feed values to chemical fertilizer application. Moreover, whole crop barley and rye within cattle slurry plots had a greater combination with hairy vetch and forage pea, respectively, and their mixture crops with legumes had higher crude protein and TDN yields within cattle slurry plots. In conclusion, it would be expected that mixed sowing with legumes in the application of cattle slurry to grass crops could be substituted for imported organic grains as dietary protein sources in feeding organic livestock.
