  • The Ministry of Environment, Ministry of Agriculture, Fishery and Forestry, and Ministry of Construction, Transportation and Maritime Affairs are in charge of livestock manure management. There are national statistics regarding the livestock industry such as the National Pollution Source Survey, Livestock Statistic Survey, and Livestock-breeding Trend Survey. The current statistical data are focused on the scale of livestock breeding and the production of livestock manure using these data, but it is difficult to establish database due to lack of information. In order to plan relevant policies including management of livestock manure, the government established database systems such as the integrated information system of livestock manure, the integrated system of national infectious animal-disease prevention, and the Sae-ol public administrative system. We have tried to suggest improvements for the comprehensive environmental information system of livestock manure management by detecting problems in each level of the livestock manure life-cycle, making use of the existing systems, and considering the electronic transfer system of livestock manure. The services and functions of this comprehensive system include information of livestock farmers, the production, collection, transportation, and treatment of livestock manure, the area of agricultural land used for livestock manure, the report of approval and results on livestock manure products, management of statistical information, management of civil affairs, and relevant mobile application services. The system is made up of three processes: first, establishment of GIS-based management database of livestock manure; second, establishment of a history management system for livestock manure transactions; and third, development of a water quality assessment system.

  • Reusing livestock manure have various advantages in securing soil organic resources, and since the costs needed for converting them into liquefied fertilizers are relatively moderate compared to normal treatment, such methods are necessary. In this study, the Recycling Capacity Assessment of Gyeonggi-do was carried out by comparing between the fertilizer demands for specific crops based on the cultivation areas and the amount of fertilizer resources that are generated from livestock manure. From this assessment, the possibility of obtaining resources by converting livestock manure into fertilizers were evaluated. The amount generated of Livestock Manure in Gyeonggi-do were evaluated by applying the emission units to the number of livestock manure. And from the amount generated of Livestock Manure, the amount of fertilizer produced from Livestock Manure were calculated by using the fertilizer a component rate. When considering the amount of fertilizer produced from Livestock Manure based on the type of livestock, N 6,626 ton/year, $P_2O_5$ 1,824 ton/year, $K_2O$ 4,480 ton/year were produced from milk cow manure, while N 5,247 ton/year, $P_2O_5$ 2,772 ton/year, $K_2O$ 2,879 ton/year, were produced from beef cattle manure. N 14,924 ton/year, $P_2O_5$ 7,205 ton/year, $K_2O$ 6,750 ton/year were produced from pigs and N 12,651 ton/year, $P_2O_5$ 4,458 ton/year, $K_2O$ 5,542 ton/year were produced by chickens. So the total amount of fertilizers that can be obtained from livestock manure were 3,668 ton/year Nitrogen, 16,259 ton/year phosphate and 19,651 ton/year kalium. And the total fertilizer demands in Gyeonggi-do were Nitrogen 27,200 ton/year, Phosphate 8,853 ton/year, and kalium 13,211 ton/year respectively. Nitrogen which had higher demands than production quantities were considered as limitation factors in crop growth. So the Recycling Capacity Assessment was carried out mainly based on Nitrogen. Since the Nitrogen quantities that can be provided by recycling livestock manure were 3,532 ton/year lesser than the Nitrogen demands, it is estimated that it would be desirable to convert livestock manure into resources. But in order to properly convert the entire livestock manure into organic resources, the seasonal situation that effects the nitrogen demands of crops along with the regional effects due to the industrial structures should be seriously analyzed. In addition, a system that can effectively produce and manage fertilizer should be established.

  • The Ministry of Environment established a plan for advancement of livestock manure management in July 2011 and finalized the "Comprehensive Measures for Advancement of Livestock Manure Management" in May 2012 complementing and strengthening the plan. In this process, it was necessary to investigate the status of discharge of livestock manure and its environmental impact, for example on rivers, groundwater, arable outflow water and soil. We investigated types of livestock husbandry, discharge of livestock manure, and production and use of organic fertilizers and presented the improvement measures of livestock manure management and organic fertilizer use. First, it is necessary to come up with measures to calculate appropriate density and numbers of livestock animals and prevent overcrowded breeding. Second, as many of the private livestock manure treatment facilities are out-dated and their long-term aerated reaction tanks are not regularly managed, it is necessary to find ways to improve those facilities through inspection and diagnosis. In addition, since existing public treatment facilities are designed to add clean water to belt filter press, additional water is needed. Therefore, it is necessary to improve belt filter press in order to decrease the extra water. Finally, although large-scale organic fertilizer plants and resources recycling centers produce good organic (liquid) fertilizers with proper components, it is necessary to establish standards for maturity of liquid fertilizers in order to facilitate efforts to turn livestock manure into resources.

  • Owing to raising number of livestock, we have a problem to solve disposal of livestock manure. We know that soil have the digestion ability of livestock manure as one of multifunctionality. I carried out to investigate of livestock manure digestion (especially pig and chicken manure) that is considered as nitrogen fertilizer in upland crops. The results were summarized as follows: 1. The amount of pig manure was(1999) 4,592,375 tons/year, and chicken manure was 4,488,166 tons/year and equivalent to 41,912 tons N/year and 76,223 tons N/year, respectively. 2. The definition of the digestion ability of livestock manure is as the maximum application amount of livestock manure without injuring soil and plant. And the calculation model of digestion ability of livestock manure(ALMD) is follows: ALMD = amount of nitrogen requirement per each upland crop / {(total nitrogen contents in livestock manure) ${\times}$ (nitrogen fertilizer efficiency of livestock manure)} 3. The amount of ability of pig and chicken manure for upland crops (dry based) were 1,142.9kg/10a and 540.1kg/10a, respectively. 4. The order of amount of digestion ability of livestock manure on upland were vegetables > orchards > miscellaneous grains(corn) > barley > potatoes > pulses > oil seeds & special crops ) fodder crops) mulberry.

  • Due to development of the national economy growth, livestock goods consumption has rapidly increased over the past 30 years. It has led livestock breeders to increase their livestock numbers. An increased number of livestock have consequently resulted in an increasing animal feces generation. According to the agricultural statistics provided by the Bureau of Statistics, livestock manure amounts to 47,235 thousand tons in 2013. To treat livestock manure, various types of treatment facilities like composting, liquid fertilization, purification, and anaerobic digestion facilities are being applied. In composting facility, there are four kinds of agitation system: escalator, paddle, screw and rotary type. In case of liquid fertilization process, there are two types of system: aeration and anoxic type. There are about 8,000 liquid fertilization facilities for treatment livestock manure in Korea. For purification of livestock manure, the treatment process is divided by three steps: Solid/Liquid separation process, Secondary purification process and advanced oxidation process. About 21 thousand tons of livestock manure was treated by anaerobic digestion facility in 2012. In every type of facility for livestock manure treatment, it is very important to choose the optimal deodorization equipment for the livestock manure treatment facility. In this study, the investigation has been carried out for six years to analyse the characteristics of livestock manure treatment facilities and related technique of Korea.

  • The livestock manure is a good source of major plant nutrients such as nitrogen, phosphorus and potassium and micronutrient that plants require. As aspect of establishment of nutrient management policy in nation scale, the use of livestock manure for agricultural purpose is a key factor for improving national nutrient balance. In this study, we evaluated the tendency of livestock manure production and amount of chemical fertilizer used in Korea from 1990 to 2011. The number of pig and chicken has been increased about two times in 2011 compared with 1990 and therefore livestock manure continually increased with the lapse of year, but cattle and dairy was not changed significantly. The chemical fertilizer consumption of nitrogen, phosphorus and potassium per hectare arable land was decreased by 54.6, 66.0 and 63.2% in 2011 compared with 1990, respectively. In contrast, the potential input of nitrogen, phosphorus and potassium to arable land through livestock manure was increased by 220, 210 and 210% during this period, respectively. Therefore we need a reasonable strategy for nutrient management such as combination of both manure and chemical fertilizers in near future.

  • As livestock husbandry has broadened from family-scale to enterprise-scale, the number of farming families has decreased in contrast to the increase of the number of livestock, and the amount of livestock manure discharged per household has increased. Livestock manure is difficult to handle and its disposal in the ocean is prohibited. Moreover, facilities that compost and liquefy manure are blamed as sources of soil, ground water, and surface water pollution because the amount of manure generated from husbandry farms causes eutrophication. In this study, livestock manure was utilized as a feedstock of hydrothermal carbonization (HTC) process to produce biochar for use as an environmental medium. The biochar was tested for iodine adsorption capability and its performance was compared with other adsorbent materials.

  • Today, a desirable way to manage livestock manure is to activate its utilization as a resource. The production of high quality liquid fertilizer of livestock manure is very important because it increases the use of various liquid fertilizer. However, the result of mature evaluation with a maturity measuring instrument for liquid fertilizer showed that the deviation of concentration between liquid fertilizer did not bring into uniformity. The result is also making sure that quality management for liquid fertilizer is not smoothly made. Quality evaluation for compost and liquid fertilizer includes physical, biological, chemical and microbiological methods, but a chemical method is mainly being implemented due to fairness and field application. Therefore, this study figured out correlation in feces and urine through regression analysis of livestock manure and tried to create a research plan to carry out efficient quality analysis of managing livestock manure.

  • Assessment of nutrient balance in region unit is important to make a decision on nutrient management in agriculture. In this study, the nutrient demand in arable land and nutrient supply from livestock manure and chemical fertilizer were estimated from pig-concentrated areas. Three regions (H, I and J) were selected on the basis of pig numbers per unit area of arable land. In H and I regions, nitrogen amount from pig manure occupied about 50% of total livestock manure. Nutrient supply was three times higher compared to the nutrient demand in each of 3 regions. Soil available phosphate of higher pig-populated area in regional unit was higher than less populated livestock area. Therefore, livestock manure-derived regional management and monitoring of soil nutrient contents is necessary for the minimization and improvement of nutrient surplus.
