  • The objective of this study was to determine the effects of various kinds of composts on the change of soil chemical properties in upland soils. Field experiments were conducted in the loam and sandy loam soils. Various kinds of composts such as poultry manure compost(PMC), cow manure compost(CMC), human excrement sludge(HES), and food industrial sludge compost(FISC) were applied annually at rates of 0, 40, and $80Mg\;ha^{-1}$ to soils grown with soybean and maize plants for 4 years during 1994 to 1997. The results of this study were as follows : The continuous application of human excrement sludge decreased soil pH up to 4.4~5.0, while other compost treatments increased soil pH compared with control plot. The EC increased initially and showed their maximum values at 20days after compost application, and then decreased up to 40 days, thereafter kept a certain level. The available phosphorous accumulated at 0~20cm depth in loam soil, and 0~50cm in sandy loam soil. Annual accumulation rates were 17% higher in sandy loam soil than loam soil. The more compost application rates and times, the higher base saturation percentage increased in upland soils. Four year's application at a rate of $80Mg\;ha^{-1}$ per year increased the base saturation percentage to 87~97% compared with 45% at control plot in the loam soil. While in sandy loam soil only three year's application of same rate increased the base saturation percentage to 81~92% compared with 30.4% at control plot. The average annual increasing rate of base saturation percentage at the same application rates of composts were higher in sandy loam soil by 2.0~3.7 times than in loam soil. The application of compost increased the exchangeable Ca, Mg, and K contents of soils by 2, 2~3, and 3~5 times, respectively, compared with the control. The contents of exchangeable cations were high in surface soil, and decreased with increase of soil depths. In the case of heavy metal content, there were no difference at the application of PMC and CMC but Ni, Fe, Zn, Cu was increased a little when the HES applied, and Ni and Cr was increased application with FISC.

  • Food waste has been actively used as a composting material in order to reduce the environmental pollution load and to enhance the recycling of resources. In this study, the longterm effects of continuous application of food waste compost to soils on both the crop production and the soil properties were examined to ensure the safety of food waste compost in agricultural use. In addition, we collected the preliminary data for establishing standard application rate of food waste compost for agricultural utilization. Based on conventional nitrogen application rate of chemical fertilizer for crop cultivation, pig manure compost $(24g\;N\;kg^{-1}$, $8g\;P_2O_5\;kg^{-1}$, and $10.4g\;K_2O\;kg^{-1})$ and food waste compost ($20g\;N\;kg^{-1}$, $20.1g\;P_2O_5\;kg^{-1}$, and $6.5g\;K_2O\;kg^{-1}$) were applied to the upland soil in $2{\times}2{\times}2m$ lysimeter in which lettuce (Lactuca sativa var. crispa), Chinese cabbage (Brassica campestris subsp. napus var. pekinensis), red pepper (Capsicum annuum), and potato (Solanum tuberosum) were grown continuously. The crops grown in soils to which food waste compost applied showed better growth responses than the control, whereas some variations were observed in the crops grown in chemical fertilizer treated soils. Continuous application of food waste compost increased the contents of organic matter, nitrogen, and phosphorus, which resulted in improving soil aeration.

  • In order to analyze environmental impact of livestock manure and organic fertilizers, this study investigated livestock-breeding and pollution loads, the status of individual and public livestock manure treatment facilities, and the status of production, supply and components of compost and liquid fertilizers in the Nonsan area. Also, on a trial basis, this study investigated the life cycle of the environmental impact of livestock manure and its organic fertilizers on stream, groundwater, and agricultural soil. The results are as follows. Firstly, were detected the range of $0.13{\sim}1.32{\mu}g/L$ of As, $0.004{\sim}0.467{\mu}g/L$ of Cd and $0.5{\sim}9.2{\mu}g/L$ of Pb as a harmful substances which show lower concentrations than person preservation criteria of water qualities and aquatic ecosystem. However, it is not clear that heavy metals affect environment such as stream, groundwater and agricultural soil. Secondly, this influence could change according to investigation time and treatment efficiency. As were detected large amounts of persistent organic pollutants(e.g. $14.24{\sim}38.47{\mu}g/L$ of acetylsalicylic acid, $1.17{\sim}2.96{\mu}g/L$ of sulfamethazine, and $2.25{\sim}174.09{\mu}g/L$ of sulfathiazole) in effluent from livestock farms and small amounts of sulfathiazole($ND{\sim}1.63{\mu}g/L$) in the stream, it is necessary to monitor POPs at individual and public livestock manure treatment facilities. However, significant environmental impact did not appear at groundwater and agricultural soil in the test area supplied with liquid fertilizers. These results could be applied to investigate the environmental impact of livestock manure through a comprehensive livestock manure management information system.

  • This study was conducted to evaluate plant growth responses and characteristics of composting poultry manure with peatmoss and cocopeat as bulking agent. Treatments were designed as follows; only poultry manure (OP), sawdust+poultry manure (SP), peatmoss+poultry manure (PP), and cocopeat+poultry manure (CP). Period maintained $50^{\circ}C$ over in compost pile of PP and CP was 35 days that longer about 10 days than that of OP or SP, and water content of PP and CP after composting 45 days 50% that was higher about 10%. While poultry manure composted, EC values of PP and CP were higher than that of SP, and pH and OM/N ratio not significant. After finished composting poultry, physicochemical properties of dried all composts were matched on Korean fertilizer guideline. As compared with OP or SP, applications of PP and CP were improved growth and productivity of lettuce, kale and mustard leaf.

  • Ocean dumping manure was prohibited in Korea until the end of 2012. Undumped manure was treated by resourcification, purification, and public process in a facility. But poor storage of untreated manure and overproduced compost can pollute river water. In this study, linear regression, Mann-Kendall, Seasonal Mann-Kendall, LOWESS trend, and Spearman's correlation analysis were conducted for investigating the changes in the water quality of Bukhan and Imjin river before and after the prohibition of ocean dumping. In 2017, the Imjin Riv er basin had more than 5.7 times liv estock breeding heads than the Bukhan Riv er basin and more than 3.5 times livestock manure. The areas of land, farmland, and nutrient balance were also higher in the Imjin River basin. Since the two basins have different environments, it is expected that the characteristics of changes in water quality due to the increase in livestock manure generation and treatment methods will be different when comparing the water quality trends before and after the ban. The result of the trend analysis revealed a decrease in EC before the ban but an increase afterward. T-N and BOD of Imjin river increased slightly before the ban but demonstrated great enhancement thereafter. Other sites and T-P exhibited no trend. The correlation analysis result showed that the increase in the number of livestock rearing was correlated with the increase in T-P of Bukhan River and BOD of Imjin River. The increase in livestock manure production was not correlated with the Imjin River basin, while a correlation was observed with the Bukhan River with an increase in T-N and EC and the decrease in T-P.

  • Curcuma longa L. (turmeric) is an important medicinal plant that has been historically used in herbal medicine and in the health food throughout Asia etc. Recently, the demands on rhizome of turmeric are increasing greatly by well-being boom, but there is not enough to meet the demands. To fulfill increasing demands, cultivation system strategies using the organic fertilizers are required to produce a greater amount of rhizome with good quality and yield. A field experiment was conducted to determine the effect of composts, NPK fertilizer(control, F), NPK + swine manure(SM) and NPK + fermentation manure from the wasted oriental medicine materials(OMWM), on rhizome yield and the content of bioactive components for quality. Our results showed that two compost applications can increase both rhizomes(24.1-25.9%) and curcumin(21.7-41.0%) yields, respectively, compared to F control. The content of amino acids increased significantly by SM and OMWM treatments. SM and OMWM application also increased the total phenol yields 7.8 and 8.7 g/10a compared with control 6.3 g/10a, the flavonoid yields 6.3 and 7.3 g/10a compared with control 5.3 g/10a, and also antioxidant activity 21.7 and 41%, respectively, as compared to the control. Especially, OMWM was more effective in total rhizomes yields and bioactivities and in the biosynthesis of curcumin and bioactive components than SM treatments, but the biological pathway was not clear, still. This experiment suggests that curcumin or bioactive components affected by adding SM and OMWM could increase the yields and quality of turmeric.

  • This study was carried out to determine a fertilization rate for productivity and nutritive value improvement of silage corn, using two kinds of composts, and to examine the potential possibility of utilization as an organic fertilizer. The experiment was conducted on the field plot at Gongiam, Kwangju, Kyunggi-Do for 3 years, from 1996 to 1998, and arranged in split-plot design with three replications. The main plots were two kinds of composts such as swine manure fermented with sawdust (SMFWS) and swine manure fermented without sawdust (SMF). Subplots were the nitrogen fertilization rates (0, 100, 200, 300 and 400kgN/ha/year). The dry matter (DM) yield increased as the nitrogen fertilization rate increased up to a rate of 300 kg N/ha, but decreased at rate of 400 kg N/ha. Dry matter yield in SMFWS treatment was higher than that of SMF treatment, but there was no significant difference between SMFWS and SMF treatments. Net energy for lactation (NEI) and total digestible nutrients (TDN) in corn increased as the fertilization rate of SMFWS and SMF increased, and crude protein (CP) content increased by the fertilization of SMFWS and SMF. No difference of CP, NEI and TDN was found between SMFWS and SMF treatments.

  • These experiments have been conducted to study the effect by microbial inoculums currently on the market of enhancing the decomposition of organic matters. As a result of studying the effect of enhancing the decomposition of rice straw and chicken manure mixed with saw dust treated with commercial inoculums, it was found that the use of inoculums have speeded up the rate of decomposing straws at the early stage. The decomposition rate of rice straws that have speeded up with the use of comcrial inoculums in at early incubation periods has slow down in the later stage while the decomposition rate of chicken manure that has slowed down in the early stage has speeded up at the later incubation. As a result, it is found that there have been no differences between the use of microbial inoculums and control. In the experiment, filamentous fungus is found to have played an important role in decomposing the rice straws and bacteria is considered to have played a greater role in the decomposition of chicken manure mixed with saw dust.

  • In this experiment, we hypothesized that pre-conditioning pig manure with microwave radiation can effectively eliminate moisture and consequently, cut down a need for expensive sawdust. For the experiment, pig manure/sawdust mixture of water content 79% was divided into 4 groups and each of them were treated with microwave for predetermined time periods, 5, 10, 15, 20 minutes. Subsequently, they were transferred to chambers (20 L) and aerobically composted. During the 2 weeks composting, air was supplied using blower (150 L per $1m^3$) and temperature and other variables were monitored continuously. When the data were analyzed, it was found, (1) moisture content was significantly decreased as radiation period extended. (2) weight reduction of compost after completion of composting was noticeably bigger in 15 min radiated group(31%), compared with 5 min (24.6%), 10 min (21.4%), 20 min (27.2%) radiated groups.

  • The fowls manure is using as fertilizers for farmland because of enough nutrients. However, excess nutrients can be washed off during a storm and affected on nearby waterbodies. In this paper, the runoff characteristics from farmland were studied to determine the washoff mass. A lab-scale reactor was designed to estimate the surface runoff and infiltration rates according to the rainfall intensity. Surface runoff water did not occur at 10mm/hr rainfall intensity, but some runoff occurred at 20mm/hr rainfall intensity. At 32.4mm/hr rainfall intensity, it shows the highest pollutant concentrations such as 686mg/L for $BOD_5$ and at 630mg/L $COD_{Mn}$. The pollutant as based on fowls manure compost was highly washed-off by subsurface water at 32.4mm/hr rainfall intensity, however the concentration was largely decreased at 43.2mm/hr rainfall intensity. The summary of the results is that the highest wash-off concentrations value shows at 32.4mm/hr rainfall intensity for $BOD_5$ and at 67.1mm/hr for T-N and T-P.
