  • Livestock manure is a valuable source of nutrients and organic matter for plant. Thus, livestock manure compost is commonly used fertilizer in organic vegetable and fruit production in many countries. However, contaminated or inadequate manure compost can give negative effect to soil microorganisms. This study was conducted to investigate the survival difference of Salmonella enterica and Listeria monocytogenes in chicken and pig manure compost under the selected environmental conditions. Commercially available manure compost (pig, chicken) was inoculated with S. enterica and L. monocytogenes. Manure compost was incubated at $25^{\circ}C$ and consistent moisture content. Samples had been collected during 200 days depending on the given conditions. S. enterica survived for 130 days in pig manure compost and over 200 days in chicken manure compost, respectively. L. monocytogenes persisted for 120 days in pig manure compost and over 200 days in chicken manure compost, respectively. It is noted that the number of S. enterica and L. monocytogenes gradually decreased over time. The results indicate that S. enterica survived longer than L. monocytogenes in manure compost at $25^{\circ}C$. S. enterica and L. monocytogenes survived longer in chicken manure compost than in pig manure compost. Increased knowledge of pathogen behavior in agricultural environments is a valuable part of future work on improving risk evaluations and, in a longer perspective, in providing data for guidelines regarding safe handling of pathogen-contaminated manure compost and soil.

  • By surveying the 70 composting plants in Gyeonggi Province, the total commercial production of livestock faeces composts (LFCs) in 2008 was estimated to be about 480,000 Mg year-1 and they were manufactured mainly by using both mechanical mixer and bottom air blower. LFCs were composed mainly of chicken faeces 29.2%, pig+chicken faeces 23.1%, pig faeces 20.0%, livestock faeces+oil cake 12.3%, pig+chicken+cattle faeces 10.8% and pig+cattle faeces 4.6%. On the basis of the current official standard which was revised on March 2010, 11 composts out of surveyed 76 ones did not meet the LFCs quality standard (LQS) due to inadequate content of water (5), OM/N (1), NaCl (2) and Zn (3). The OM/N declined by adding chicken faeces and oil cake, while Ca content increased by the addition of chicken faeces and NaCl increased by adding cattle faeces.

  • 계분과 돈분퇴비의 연용에 따른 토양의 이화학적 특성을 검토하기 위하여 0~120 Mg/ha 범위의 퇴비를 3년간 연용하였다. 토양의 pH는 시험전 7.1에서 계분 및 돈분퇴비 3년 연용후 6.4~6.9 수준으로 낮아졌으며, 양이온치환용량(CEC)은 퇴비시용에 따라 무비구에 비해 증가하였으나, 연용에 의해 감소되는 경향을 보였다. 치환성양이온함량은 3년 연용후 현저히 증가되었으며, 전기전도도(EC)는 돈분 120Mg/ha 처리구에서 최대 1.25 ds/m 수준까지 높아졌다. 퇴비의 연용에 의해 경도, 용적밀도가 낮아지고, 토색이 짙어져 암갈색을 띠는반면, 공극율은 증가하였다. 계분 및 돈분퇴비를 3년간 연용한 결과 1년, 2년 시용시 돈분퇴비 처리구가 계분 처리구에 비해 토양 중 더 많은 양분축적을 보였으나 3년 연용시에는 큰 차이가 없는 것으로 나타났다.

  • This study was carried out to investigate changes of physico-chemical properties and microbial activity during the early stage of composting with pig and chicken manure. The results were as follows; 1. The temperature was rapidly increased from the 3rd to the 7th day, and especially the pig manure compost preparing with enzyme was maintained $56^{\circ}C{\sim}69^{\circ}C$. 2. The pH range was shown $7.7{\sim}9.3$, and the pH level increased from the 3rd day to 25th day. Also after the 25th day the pH level decreased gradually. 3. The C/N ratio in the pig manure compost decreased 16.8 at the 30th day, while the compost containing enzymes decreased 19.2 at the 30th day. Chicken manure compost showed similar results at the 28 of C/N ratio at the 30th day with enzyme treatment. 4. The total ammount of sugar in pig manure compost was $6,000{\sim}7,000mg/kg$, while the chicken manure compost was $2,000{\sim}4,000mg/kg$. However, there was no significant difference in view point of enzyme treatment. 5. Cellulase, phosphatase and xylanase activity were continually increased, however amylase and urease activity were not changed during composting.

  • This survey was conducted to promote the environment-friendly use and recycling of livestock feces by obtaining information about the current state of livestock feces composts manufactured in Gyeonggi Province. Therefore, some aspects of quality and manufacturing techniques of livestock feces composts (LFCs) were examined especially in relation to the LFCs quality standard (LQS). By surveying the 70 composting plants in Gyeonggi Province, the total commercial production of LFCs in 2008 was estimated to be about $480,000Mg\;year^{-1}$ and they were manufactured mainly by using both mechanical mixer and bottom air blower. LFCs were composed mainly of chicken feces 29.2%, pig+chicken feces 23.1%, pig feces 20.0%, livestock feces+oil cake 12.3%, pig+chicken+cattle feces 10.8% and pig+cattle feces 4.6%. On the basis of the current official standard which was revised on March 2010, 11 composts out of surveyed 76 ones did not meet the LQS due to inadequate content of water (5), OM/N (1), NaCl (2) and Zn (3). The satisfaction rate to LQS by manufacturers was 100% in the composts produced by farmer's cooperative societies, 80.7% by civil factories, and 44.4% by farming guilds, respectively. The OM/N declined by adding chicken feces and oil cake, while Ca content was increased by the addition of chicken feces and NaCl was increased by adding cattle feces.

  • In this study, the characteristics as well as the maturity and stability of chicken manure collected from nine chicken farms in South Korea during the summer and winter seasons of 2014 are evaluated. The physicochemical parameter values of the manure, such as BOD, $NO_3-N$ and $PO_4-P$ etc. were determined using the Korea Standard test Method, HPLC, and APHA standard methods. The results showed that the alkalinity content and COD concentration in winter chicken manure were higher than those of summer chicken manure. The moisture content of summer manure was positively correlated with almost all of the other parameters of the manure, whereas it was negatively correlated with almost all of the other parameters in the winter manure. According to the criterion of C/N ratio, chicken manure indicated good quality compost. However, composted chicken manure showed immature and unstable compost when considering the criteria of the $NH_4-N/NO_3-N$ ratio and $NH_4-N$ concentrations.

  • This experiment was carried our in order to study effect of alum sludge compost of water treat-ment plant on the growth of Korean lawngrass (zoysia japonica Steud.) and on the change of soil chemical properties. Alum sludge compost was made out of chicken feces, sawdust and alum sludge. The results obtained are summarized as follows : 1. Alum sludge compost was appropriate for organic fertilizer of turfgrass management in golf course. 2.Application of alum sludge compost improved the chemical properties of soil such as pH, available phosphorous and exchangeable calcium. Also the growth of Korean lawngrass grown by the mixed application of alum and compost was more effective than that in single application of compost. 3.Chlorophyll content of Korean lawngrass had no differences in several treatments. 4. Alum promoted the uptake of potassium, calcium and the yield of dry weight hut the yield of dry weight was not affected by chemical fertilizer. 5.Alumimum toxicity was decreased by the mixed application of alum and compost but increased by single application of alum.

  • The veterinary antibiotics treated to livestock have a potential risk to reach to soil and water environment, and eventually be taken up by plants. The objective of the study was to investigate the effect of zeolite and shell meal fertilizer amendment on antibiotic uptake by plant when veterinary antibiotics in chicken manure compost were applied to agricultural land. Model antibiotics used in the study were chlortetracycline (CTC), tylosin (TYL), and sulfamethazine (SMT). Chlortetracycline level in lettuce was decreased to less than $0.08ug\;kg^{-1}$ by application of zeolite as compared with about $0.26ug\;kg^{-1}$ for control without amendment on 33 days after transplanting. Tylosin was not detected for all the treatment. Sulfamethazine levels in lettuce ranged from 11 to $19{\mu}g\;kg^{-1}$ on a fresh weight basis and gradually decreased with time. Zeolite application decreased the SMT levels in lettuce by greater extent than shell meal fertilizer amendments. Results from the 61-d greenhouse experiment imply that application of zeolite at a rate of $1.5Mg\;ha^{-1}$ or shell meal fertilizer at a rate of $2.0Mg\;ha^{-1}$ can reduce CTC and SMT concentration in lettuce cultivated in soil fertilized with antibiotic-contaminated chicken manure compost.

  • The effects of turning frequency of in-vessel composting on ammonia emissions during composting of separated solids from swine slurry/sawdust mixtures and performance of biofiltration using the chicken manure compost were investigated. Separated solids from swine manure amended with sawdust was composted in a 226 L laboratory-scale in-vessel reactors under various turning frequency and continuous airflow (0.6 L/min.kg.dm) for three weeks. Three laboratory-scale manure compost biofilters were built to treat effluent gas from the composting of separated solid from swine manure amened with sawdust process. These experiments were continued over a period of three weeks. The composting of separated solid swine manure amended with sawdust and manure compost biofiltration system were evaluated to determine the turning frequency type that would be adequate for the rate of decomposition and compost odour reduction. The compost odour cleaning was measured based on ammonia gas concentration before and after passing through the manure compost biofilter. The average ammonia odor reduction in the manure compost biofilter was 96.9 % at R1 (no turning), 99.4 % at R2(once a day turning) and 89.0 % at R3(twice a day turning), respectively. The efficiency of ammonia reduction was mainly influenced by the turning frequency.
