화학비료에 의존한 경작으로 점차 토양은 산성화되고 지력의 저하가 경종농업분야에서 큰문제로 대두되고 있으며 한편에서는 계분의 처리문제로 양계농가의 어려움을 더해가고 있다. 계분을 효율적으로 발효처리한다면 양계농가의 골치거리를 해결할 뿐만 아니라 돈(금)으로 바꿔 경영에 보탬이 되고 국토의 지력상승면에서도 큰 기여를 할 수 있을 것이다. 계분발효의 원리와 방법을 제시한다.

This study was conducted to evaluate effects of compressed expansion rice hull (CERH) as bulking agent on physicochemical properties of composting poultry manure (PM) and of its fertilization on lettuce and pak choi growth. Treatments were designed as follows; sawdust treatment (90% PM + 10% sawdust; SP), peatmoss treatment (90% PM + 10% peatmoss; PP), and CERH treatments [PCR1 (90% PM + 10% CERH 1.3 mm) and PCR2 (90% PM + 10% CERH 3.0 mm)]. Physicochemical properties such as temperature, water content, pH, and total carbon of composted poultry piles for 31 days were unaffected by various bulking agents. However, total nitrogen content in compost pile was higher in PP and PCR1 than that of SP or PCR2. After composting for 31 days, content ranges of N, P2O5, and K2O in the composting PM piles were 19.1~19.7%, 47.6~51.6%, 2.76~3.65%, and 2.53~2.90%, respectively. As compared to SP treatment, dry weight of lettuce treated with PP and PCR1 increased by more than 10%, but only in PP for pak choi. These results indicated that CERH 1.3 could be used as bulking agents for composting PM on behalf of peatmoss or sawdust.

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.

정부는 증산위주의 고투입농법에 의존한 결과 화학비료 과다사용으로 토양의 양분의 불균형을 초래하고 있으며, 환경보전 및 식품안전에 대한 국민의 관심이 커짐에 따라 2000년부터 친환경농업 5개년 계획을 수립하여 추진하고 있다. 이 계획에 따라 축산분뇨 자원화를 서두르고 있다. 특히 자원화 효율이 좋은 계분은 경정농가로부터 인기가 매년 상승하고 있는 상태이다. 그러나 경종농가에 판매되는 발효 계분은 현행 비료관리법상 1일 생산되는 부산물비료가 1일 1.5톤이상이면 비료업 등록을 하도록 되어 있으며, 비료업에 등록하여 발효계분을 판매하고 싶어도 각종 규제에 걸려 판매하지 못하는 농가가 많고, 계분판매는 엄두도 내지 못하고 오히려 비용을 지불하고 있는 농가들이 있어 이에 대한 현황을 점검하고 해결방안을 알아보았다.

The experiment was conducted to evaluate the effects of organic fertilizer. Sarang of fermented poultry manure. Miwon glutamic acid fertilizer and poultry manure, on the growth and yield of radish cultivated in spring and autumn. 1) The growth of leaf length, leaf weight, root length, root diameter and root weight of radish in two culture types was stimulated in order of NPK, fermented poultry manure + 1/5NK, fermented poultry manure, poultry manure and control treatment, and chlorophyll and nitrogen content of leaf were increased in order of the above mentioned fertilizers.2) Yield decreased in fermented poultry manure plot of 450kg application comparison with NPK plot but the one of 1800kg fermented poultry manure was increased. The yield of 450kg Sarang plot was sufficient as compared with Korean average yield of spring and autumn culture.3) The difference of growth of radish between treatments of fermented poultry manure and NPK was lowered by continuous application of Sarang organic fertilizer.4) Soil nitrogen content and exchangeable Mg were similar in all treatments but soil pH, the contents of organic matter, $P_2 O_5$ and Ca were high in the fermented poultry manure treatment.

This study was carried out to investigate the chemical characteristics of different organic liquid fertilizer during fermentation at plastic house in Chungbuk Agricultural Research and Extension Service. Chicken dung, soybean meal, and rice bran were used for nutrient sources. The obtained results from this study were summarized as follows; Total nitrogen contained the highest in soybean meal as 55 mg·kg^-1, and phosphate and potassium contained high in chicken dung and rice bran in organic liquid fertilizer materials. The pH of chicken dung was near 7.0, that of soybean meal and rice bran indicated acidity(pH 3.8~4.4). The electrical conductivity of chicken dung consistently increased during fermentation, and that of soybean meal and rice bran increased and decreased early season and increased at late incubation period. Hydrogen sulfide gas occurrence of chicken dung was 3,200 mg·L^-1 at early season and 1,600 mg·L^-1 at late incubation period, and that of soybean meal and rice bran treatments were not or very low concentration of hydrogen sulfide gas during manufacturing period. The nitrogen and calcium content of organic liquid fertilizer were the higher in chicken dung and soybean meal than rice bran. The phosphate and magnesium content of rice bran was the high as 5.6 g·kg^-1 and 1.5 g·kg^-1, respectively. There was no difference in potassium content among the different liquid fertilizers during fermentation.
