This study analyze the economic effect of chemical fertilizer. We used the input and output data, and the analysis variables include production output nitrogen, phosphoric acid, potassium, seeds, and labor. The main results are as follows. First, for spring potatoes, potassium increases to a certain level of output, but over a certain stage, the output decreases as the input increases. Optimal use of potassium in the calculation of spring potatoes can achieve the effect of reducing input costs and increasing output simultaneously. Second, radish In autumn, nitrogen increases to a certain level, but over a certain stage it represents a reverse U-shaped relationship in which output decreases as input increases. This means that reducing the amount of fertilizer input increases the output. This means that soil-related agricultural big data can contribute to the management of nutrients and greenhouse gas reduction in agricultural land.

This study was undertaken to evaluate the quality characteristics and antioxidant characteristics of commercially available mixed grains in Korea. The quality characteristics of mixed grain products studied were the mixing ratio, water binding capacity, water solubility, swelling power, and pasting characteristics. The antioxidant characteristics assessed the total polyphenol, flavonoid contents, DPPH and ABTS radical scavenging activities. The mixing ratio of commercially available mixed grain products consisted of 5~25 kinds of grains, with maximum products containing 15-grain products. The water binding capacity, water solubility, and swelling power in commercially available mixed grain products were 99.83~122.83%, 6.91~39.26% and 7.76~86.92%, respectively. The peak, trough, breakdown, final and setback viscosity were $31.53{\pm}20.17RVU$, $25.24{\pm}13.22RVU$, $6.29{\pm}7.43RVU$, $50.27{\pm}25.84RVU$ and $18.74{\pm}8.68RVU$, respectively. Total polyphenol and flavonoid contents were $817.14{\sim}2,524.29{\mu}g\;GAE/g$ and $106.36{\sim}1,099.09{\mu}g\;CE/g$, respectively. The DPPH and ABTS radical scavenging activities were 31.91~151.70 mg TE/100 g and 28.09~119.92 mg TE/100 g, respectively. Products with high phenol content and radical scavenging activity were found to contain greater proportion of brown rice, colored rice, barley and soybean.

This study was carried out to select the promising forage crops for forage production in paddy field of NLRI, RDA, Suwon from 1999 to 2001. The species of forage crop used in this experiment were barley(3 varieties), wheat(2), rye(3) and Italian ryegrass(IRG, 3). Stages of heading, milk and yellow ripe of barley were 1 May, middle May and late May, respectively. In milk to yellow ripe stage, dry matter(DM) and total digestible nutrient(TDN) yield of barley were $7.30{\sim}9.58$ MT and $4.75{\sim}6.24$ MT per ha, and Albori was the most promising variety among the barley. The growth of wheat was a little late compared to that of barley. but it seemed to be crop having higher forage yield and nutritive value. In milk to yellow stage, DM and TDN yield of wheat were $8.17{\sim}10.82$ MT and $5.33{\sim}7.31$ MT per ha. Heading stage of rye was 27 to 29 April, and it seemed to be suitable for harvest at heading to flowering stage because of heavy lodging after flowering. In flowering stage, DM and TDN yield of rye were 10.18 and 6.03 MT per ha. Heading stage of early maturing IRG was 7 May and it seemed to be good for harvest at flowering stage of middle May in cropping system. In flowering stage, DM and TDN yield of early type IRG were 4.48 and 2.96 MT per ha. The results demonstrated that the promising forage crops for forage production in paddy. field were rye and barley(Albori) in Middle region, and rye harvesting at early May was recommended when considered middle May of rice transplanting period, and rye and barley considered late May of rice planting period. Also early maturing and high yielding IRG variety was strongly needed.

These experiments were conducted to determine the effects of soils treated with different soil management, methods, fertilizers and crops on soil microflora and its number for constructing the environmentally sound agriculture modeling of the upland soils. These experiments show that physico-chemical soil characteristics was different in upland soils treated with different soil managements and fertilizers applied. Also soil microflora and its number were effected from crops cultivated with different soil managements in these experiments. The number of Erwinia sp. in chinese cabbage cultivated field on Daekwanryung especially was apparently increased in soil cultivated with potato relative to corn. It was appeared that the number of Fusarium sp. in soil was more effected from kind of fertilizer applied than crops cultivated.

The purpose of this study was to investigate the effects of the rural migration factors, degree of preparation for migration, lifestyle conditions and support policies reflected against the family satisfaction of the migration. In this study family factors were used as control variables. Independent variables for this study will consist of the factors of rural migration, the degree of preparation for migration, living conditions of the farmers and the support policies, where as the dependent variable is the satisfaction of migration with an adjusting factor of the family satisfaction which will be further analysed to identify its effects on the dependent variable. For this study, a questionnaire survey was conducted for the residents and 237 valid questionnaires were collected. Multiple regression analysis was performed based on the collected data where demographic attributes being the controlling variable, and regression analysis was performed for the adjusting variable of the family. As the economic factor increases, the level of satisfaction generated to be higher in rural migration. As for the degree of preparation, living condition and support policies resulted, great quantity of green nature, safety and agriculture startup support, respectively, indicated a positive effect to the satisfaction level of migration. From the results, adjustment effect of the family factors on the economic, nature, convenience and satisfaction of the migration have appeared. The conclusion of this study is that policy support, regional stability, and economic gain are the most important factors to increase satisfaction and to reduce re-migration rate to city.

As Korean traditional peasant farming has come to a commercialization since 1970s, the spatial structure of Korean agriculture also has been gradually restructured by principle of not subsistance but economy. This epochal transformation of agriculture and its spatial structure in Korea are comparable with the first agricultural revolution in Europe. Facing this turning point, it is essential to redefine the nature and significance of agricultural geography in Korea through the review of the outcomes of about 200 studies published since 1950s in Korea of which twelve is concerned with locational analysis. The purpose of this study is to review the trend and characteristics of location studies on Korean agriculture. Major findings are as follows: (1) Since 1950s the location studies of agriculture recorded only 12 papers which occupy no more than 6% of studies of agricultural geography in Korea. This fewness suggests that the location study of agriculture in Korea is yet at the stage of beginning. (2) In spite of the fewness the studies, carried out mainly in 1980s, contributed considerably to clarify the locational characteristics of Korean agriculture especially in the spatial variations of crops, dairy farming and cropping system, the impacts of agricultural labors, the location strategy of mountain agriculture, and the responses of farmers to hazard. (3) In approach and methodology, two thirds of the studies has taken traditional empiricist view and other, positivist. And most studies adopted classic and neo-classic locational theories as their theoretical base in description and explanation. In degree of development, the location studies of agriculture in Korea seems to be about 20 years delayed compared to that of the advanced countries in terms of approach and methodology. (4) Such tradition of the location studies reflects not only the conservative nature of agricultural geography of Korea but also the early stage of capitalism of Korean agriculture.
