Even though Korean consumers have shown the strong preference for environmentfriendly agricultural products, the real market of environment-friendly agricultural products may reach a plateau. In order to overcome this problem, researchers should find the more specific consumers’ needs, including taste, flavor, shape, and others. and offer some implications to farmers and marketers. The object of this paper is to analyze the determinant factors of Korean consumers about environmentfriendly carrot and oriental melon, through survey and fuzzy multi-criteria decision making approach. The results of analyses present that Korean consumers have the unique determinant factors about environment-friendly carrot and oriental melon, which are different from conventional carrot and oriental melon. Korean consumers’ experience of the buying of environment-friendly vegetable is also influential in the determinant factors. Findings and implications from this research may be useful to Korean producers and other researchers.

The purpose of this study is to analyze willingness to pay (WTP) for organic agricultural products. To accomplish the objective of the study, a consumer survey was conducted. Based on the pilot survey results, parametric survival model was used to analyze the WTP for organic products. The estimation results showed that the WTP for organic agricultural products is 1.4-fold when compared with the conventional products, which is lower than the current price by about 30 percent. The analytical results also showed that such variables as gender, recognitions for organic agricultural products, and consumers’ income have very significant effects on the WTP, and that there are no differences among WTPs by consumption goals. Based on major findings, the most effective countermeasure was suggested for expanding of organic food consumption through the premium reduction of organic products. Reducing the costs of production and distribution, supporting farmers’ income by direct payment system were presented. Furthermore, it is needed to allocate more budget for promoting the consumption and distribution of organic agricultural products, and for enhancing conservation of agricultural environment.

The objective of this study is to introduce a program for environmental conservation in environment-friendly agriculture. For this, we first analyze a performance condition of environment-friendly agricultural districts and zones. And then we survey difficulties on implementation and main points for spread of environmentfriendly agriculture. Finally we forecast an effectiveness and realizability on program for environmental conservation in environment-friendly agriculture. As a result, it is necessary to plan policies on qualitative as well as quantitative growth in environment-friendly agriculture. The results of this study will be meaningful to make policies on spread of environment-friendly agriculture.

To internalize climate-related external costs from agricultural production and food consumption Pigou taxes and carbon credits increase private costs for food. Voluntary GHG reduction program for carbon-neutral food can be advantageous over such policy measures since they avoid higher food prices for the poor. The pilot project of low-carbon agriculture certification system is to reduce GHG emissions from agricultural production and enhance the competitiveness of domestic agricultural products. This study examines producers’, distributors’, and consumers' perceptions of the low-carbon agriculture certification system and analyzes alternatives to promote the low-carbon certificated agricultural products.

The application of animal manure on farm fields is one of the most economical ways. However, the continuous application of manure in paddy fields might change soil properties influencing the growth of rice plant. Thus, this study was conducted to investigate the changes in selected chemical and biological properties of soils and rice production as affected by the applications of two different fertilizer sources, which were the consecutive applications of liquid swine manure (LSM) and chemical fertilizer (CF), during the three experimental years, from 2012 to 2014. Application amount of LSM was based on 100% of nitrogen fertilizer recommendation rate for rice cultivation estimated by soil testing. Plant height and tiller number in rice at the first year of liquid swine manure manure plot were lower than those of chemical fertilizer plot. Height and tillers of rice in liquid swine manure plot were higher than those of rice in chemical fertilizer plot after consecutive application for 3 years. Rice yield In the first year of application was decreased by 7% than that of chemical fertilizer, but the yield of rice in the third year of application in LM 100% plot was increased by 8% compared to the chemical fertilizer. Toyo-taste value of milled rice in LM 100% was decreased by increasing of protein contents and decreasing rate of perfect grain. The K and Zn contents in the soil were increased in the plots of consecutive LSM application. The results implied that the liquid manure may neither decrease the yield of rice and nor increase soil properties except K and Zn in the soil, and decrease rice quality.

After carrying out on-the-spot observation targeting each farmhouse of large-scale environment-friendly agricultural district (LEAD), Suncheon, Sancheong, Jangheung, Yeongam, Hamyang, Okcheon, and Jeongseon in 2015, only one LEAD, a farmhouse in Jangheung had used sustainable compost coming out under their own non-antibiotic livestock. The soil pH and EC at a depth of 0-20 cm in the seven LEADs were ranged between 5.3-6.6 and 0.4-1.2 dS m-1, respectively, with 0.03- 0.27% for T-N concentration, 22-322 mg kg-1 for P, and 0.05-0.29 mg kg-1, which were, in particular, low a farmhouse in Jeongseon. When intensively surveying on each farmhouse of Suncheon, Jangheung, and Okcheon for a growing period, seasonal soil pH was maintained above 6.0 and high in a farmhouse in Okcheon, with similar soil EC observed among the three LEADs. Seasonal soil T-N was 0.1% higher on the farmhouse in Suncheon than other two LEADs, with higher seasonal soil P observed on the farmhouse in Okcheon and higher soil K in the Jangheung. T-N concentration in rice (Oryza sativa L.) crops was the highest in Jangheung, and concentrations of T-N, P, and K decreased in a season. Plant height and number of tillers per hill were the highest on the farmhouse in Okcheon, where was similar or low plant diameter and SPAD levels compared to other two LEADs. Dry weight (DW) before harvest was ranged between 52-63 g, and DW, rough rice yield (kg), brown rice/rough rice (%), brown rice yield (kg), head rice (%), and broken rice (%) were not significantly different among the three LEADs. Total annual gross production ha-1 was the highest on the farmhouse in Okcheon (16,230,000 won) planting with high class of variety, ‘Milky queen’ atearly maturation, which was expected to be increased on an agricultural income. However, high amount of fertilizer was applied for growing the following crops on the farmhouse in Okcheon, affecting the highest balance of T-N, P, and K more than 200 kg ha-1.

The present study investigated the effect of inclusion of chromium propionate (Cr-P) and lysophopholipid (LPL) in diet on blood parameters and meat quality of Hanwoo steer. Feeding trial was performed from late fattening period to slaughter and blood parameters (insulin, blood glucose and non-esterified fatty acid (NEFA) concentration) and meat quality were examined. Total 4 experimental groups including control (no addition), T1 (Cr-P 0.2%), T2 (LPL 0.2%) and T3 (Cr-P 0.1% + LPL 0.1%) were employed. For blood parameters, insulin concentration in T1 and T3 showed an elevating patterns from 3.13 μU/mL to 3.35 μU/mL (T1) and from 4.38 μU/mL to 5.23 μU/mL (T3). The changes of NEFA in all groups were detected as a decreasing patterns according to days of feeding. However, significant difference was not found. In growth performance, T2 showed greater daily gain and T1 showed greater carcass yield compared to others. However, there were no significance in difference. In meat quality, T1 showed greater yield and intra-muscular fat levels and lower sharing force compared to others. However, significant differences were not detected.

Accumulation of excessive salt in Reclaimed coastal tidelands can reduce crop yields, reduce the effectiveness of irrigation, degradation of soil structure, and affect other soil properties. These salts has shown to cause specific ions in the plant over a period of time leads to ion toxicity or ion imbalance and a continuous osmotic phase that prevents water uptake by plants due to osmotic pressure of saline soil solution. This review focuses on the characteristics of salt-affected soils, mechanisms of salt-tolerance plants, desalinization technology, and soil management to maintain sustainable agro-ecosystem in salt-affected soils.
