  • This study was carried out to determine the effects of pig slurry on growth of potato (Solanum tuberosum L. cv. Dejima), soil chemistry properties and infiltration water quality in volcanic ash soil and non-volcanic ash soil of Jeju. Fertilization of liquid pig manure was based on nitrogen. In volcanic ash soil and non-volcanic ash soil, there was no difference in the height and diameter of stems in chemical fertilizer and liquid pig manure application treatments. Also yields of potatoes were no significantly difference in chemical fertilizer and liquid pig manure application treatments. pH in all soil was increased by application of liquid pig manure compared to the chemical fertilizer plot. Contents of exchangeable K in all soil were accumulated excessively by fertilization of pig manure 100% compared to the chemical fertilizer 100%. But there was no difference between the chemical fertilizer 50%+liquid pig manure 50% and chemical fertilizer 100%. No difference between the chemical fertilizer and liquid pig manure was observed in available phosphate, exchangeable Ca and Mg. $NO_3$-N concentration of infiltration water sample collected at 70cm of soil depth was lower non-fertilizer than chemical fertilizer and liquid pig manure application treatments. In volcanic ash soil, the $NO_3$-N concentration of infiltration water was decreased from early, except liquid manure 100%. In non volcanic ash soil, the $NO_3$-N concentration of infiltration water increased until October 8, but then was reduced. In all soils, $NO_3$-N concentration of infiltration water was higher in the liquid manure 100% than those in the chemical fertilizer 100% and chemical fertilizer 50%+liquid pig manure 50%, but there were no differences. In conclusion, the growth of potato, fertilization of soil and $NO_3$-N content of infiltration water were not different between chemical 50%+liquid pig manure 50% and chemical 100% plot. So, liquid pig manure could be substituted for some amount of chemical fertilizer.

  • The objectives of this thesis were to search for effective methods of the livestock manure management through analysis of the livestock manure management cost and prepare for cuts in greenhouse gases emission by applying CDM in the fields of livestock in 2013. In the situation where most farmhouses are disposing the pig manure by ocean disposal, it is urgent to make an alternative plan since ocean disposal will be prohibited from 2012. Biogasplant is being highlighted from the point that can produce heat and electricity by using methane generated when the manure is disposed, and that can produce barnyard manure and liquid manure. As biogasplant generates energy using methane, it will contribute to decreasing global warming with the effect of greenhouse gases reduction, and trading emission reductions through CDM will result in creating revenue.

  • This study was conducted to investigate the effect of liquid pig manure application on soil chemical properties in rice - Chinese milkvetch rotation. Field experiment was designed with APLM 0 (Chinese milkvetch + Liquid pig manure $0L\;m^{-2}$), APLM 50 (Chinese milkvetch + Liquid pig manure $1.8L\;m^{-2}$), APLM 75 (Chinese milkvetch + Liquid pig manure $2.7L\;m^{-2}$) and APLM 100 (Chinese milkvetch + Liquid pig manure $3.6L\;m^{-2}$), respectively. The concentration of O.M, T-N, Avail. $P_2O_5$, K, Ca and Mg at different liquid pig manure levels in soil were generally high in the order of APLM 100 > APLM 75 > APLM 50 > APLM 0. Especially, T-N concentration of soil in APLM 100 was 1.4 times higher than APLM 0. The yield of rice in APLM 100 was $636kg\;10a^{-1}$ (increasing yield 5.3%) compared with APLM 0 in rice-Chinese milkvetch crop rotation. Therefore, application of liquid pig manure was useful in rice - Chinese milkvetch crop rotation.

  • The nutrients in livestock manure produced during fermentation processes in public livestock recycling centers are used as fertilizers. However, the large amounts of swine manure produced in intensive livestock farms can be a nonpoint source of pollution. In this experiment, we investigated the chemical properties, inorganic components, and heavy metal contents in 101 samples of liquid swine manure collected from 28 public livestock recycling centers throughout the nation. Results showed that the average pH of the samples was alkaline (pH range 5.18 to 9.54), and their maximum EC was $53.2dS\;m^{-1}$. The amounts of total nitrogen and total phosphorus were in the range of 1000 - 2000 and $200-800mg\;L^{-1}$ while potassium, which constituted 47% of the total inorganic ions recovered from the liquid swine manure, amounted to $1500mg\;L^{-1}$. The most distinctive heavy metals recovered from the liquid swine manure were copper and zinc although the amounts of both heavy metals were much lesser than those of the standards as livestock liquid fertilizer set by the Rural Development Administration. On the other hand, the amount of nitrogen decreased rapidly with an increasing fermentation period from immature to mature, assumed to be lost as volatile compounds, such as ammonia, which are the major odor components during the fermentation process.

  • Establishment of a new concept of environmental friendly livestock manure management is required based on the facts. But now liquid fertilizer quality in korea shows a large difference among regions and the regulations are uncertain. Focusing on precedent study on main level-grading factors of liquid fertilizer quality certification, the study collected laws and standards related to liquid fertilizer of livestock manure at home and abroad and produced evaluation standards. Liquid fertilizer was divided into four factors (fertilizing value, harmfulness, stability and uniformity). According to each item, scores were awarded based on 16 details: fertilizing value (Nitrogen concentration, the whole concentration of Nitrogen, Phosphoric acid and Kalium), harmfulness (heavy metals, pathogenic microorganism and antibiotics), stability (maturity degree and odour), uniformity (EC, BOD, SS, moisture content and salt). The grade of liquid fertilizer, A (42~48), B (34~41), C (26~33) were rated using total scores.

  • The purpose of this study was to assess nonpoint sources (NPS) pollution affected by liquid manure and regulating gate in a small agricultural watershed. The study area, which is a wide plain farmland, was operating by the Buyong regulating gate in order to maintain irrigation water level during irrigation period. Consequentially, runoff only occurs through the gate at each event in rainy season for avoiding farmland inundation. In addition, the usage ratio of liquid manure in the study area has been increased greatly since 2014. Discharge loads at the Hwaingsan bridge subwatershed were 1.2 times for T-N, 4-10 times for T-P, and 3-8 times for TOC compared with the Soyang watershed (control) during study period. The reason was that NPS pollutants from upper Gpeun and Sangri bridge subwatersheds, which are widely spraying with livestock liquid manure, were stack at this subwaterehd because of regulating gate in non-rainy seasons. A number of agricultural watersheds in Saemangeum watershed are affected by regulating gate and vigorous livestock activities so that substantial management schemes under controling regulating gate are needed for minimizing livestock related NPS.

  • Pig slurry, urine and fermented liquid manure were evaluated measuring electrical conductivity (EC), dry matter (DM) contents and other components. Samples were collected during a period from February to April, 2001: slurry samples from 70 storage tanks, urine samples from 19 and 20 fermented liquid manure samples from 109 pig farms in Jeju. Samples were analyzed for pH, EC, DM, $NH_4$-N, K, P, Ca, Mg, Na, BOD, S-S, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn and OM. Relationships between EC or DM and various mineral and $NH_4$-N contents were examined using linear regression. EC, DM, all mineral contents and $NH_4$-N were higher in slurry samples than in urine or fermented liquid manure. EC, $NH_4$-N, Ca, Mg and Na concentration was similar in urine and fermented liquid manure, but K and DM values in liquid manure were twice as much as in urine. P concentration was higher in urine than in liquid manure. $NH_4$-N and Na in slurry, $NH_4$-N in urine and $NH_4$-N, P and Ca in fermented liquid manure were highly correlated with EC, while $NH_4$-N, P, Ca and Mg in slurry, $NH_4$-N and Ca in urine, and K, P, Ca, Mg, and Na in fermented liquid manure with DM (P<0.05). BOO in slurry (22,520 mg/mL) was higher than that in urine (4,763) and fermented liquid manure (2,701). Results indicated that slurry is a better fertilizer source than urine or fermented liquid manure. However, slurry may pollute soil more than urine or fermented liquid manure when applied to land, although the levels are not above the permit.

  • A more efficient use of nutrients from organic sources can benefit both farmers and water quality in agriculture. In this paper we reviewed information related to the regulations and guidelines of a swine liquid fertilizer to propose an establishment scheme for the official standards of swine manure slurry as a liquid fertilizer for organic farming. According to the law of establishment and designation of official standard of fertilizers, the liquid fertilizer made with pig liquid manure belongs to the byproduct fertilizer as of one of organic fertilizer. However, the official standards for byproduct fertilizers including the liquid fertilizer set by the Rural Development Administration (RDA), especially for a liquid swine manure fertilizer, should be revised to meet the goals of laws pursuing the environmentally sound agriculture, especially for organic farming because the terms and relevant standards need additional specific standards alike the standards such as impurities and parameter for declaration in EU. Therefore, it is suggested that official standards for byproduct fertilizers should be revised with respect to nutrient, salt content as of SAR and Na content instead of NaCl. Also we need to develop the maximum limit of heavy metals in soil to which the liquid fertilizer can be applied, as well as application rate depending on EC of the liquid fertilizer.

  • To prevent the inappropriate treatment of livestock manure and induce the correct circulation of them into farmland, systematic monitoring and management by the treatment and circulation stage of livestock manure are required. The purpose of this study was to apply ubiquitous information communictation technology (u-ICT) to a livestock waste management system for better treatment by utilizing ubiquitous computing technology in the livestock sector. Elements and levels of applicable u-ICT technology for efficient livestock manure management were derived by analyzing previous researches. In addition, a conceptual diagram of an integrated management system was suggested by analyzing the existing liquid fertilization process.

  • Recently, manure emissions associated with the numerical increment of the domestic hog-breeding have increased, but it has been banned from ocean dumping by the United Nations Convention in 2012. To find out the site for spraying in large quantity of liquid manure fertilizer, we selected one grass plantation, which has the largest amount of grass production, in Jangsung, South Korea. We spread not only chemical fertilizer but also liquid manure fertilizer on the zoysiagrass plantation and researched the effect on the grass growth and development, soil chemical property, and seepage water of dike. As the test results, spread by compounding chemical fertilizer and liquid manure fertilizer and it is possible to substitute for some chemical fertilizer in terms of nutrients accumulation and the grass growth and development. Additionally, it gives less effects to soil chemical property and is efficacious to effective microorganism growth of soil. Therefore, adding liquid manure fertilizer will lead to reduce almost all the amount of chemical fertilizer usage. It is also expected to help for livestock manure management and to influence reducing the production cost of the grass plantation. However, to spread liquid manure fertilizer contaminates water system. For this reason, monitoring continuously, we need to find out improvement plans of the fertilization method in order to increase the usage of liquid manure fertilizer.
