본 연구는 가축분뇨의 처리형태별 시용수준에 따른 목초의 생산성과 질소의 이용효율 및 질소의 용탈에 의한 환경오염에 미치는 영향을 파악하기 위하여 화학비료, 톱밥발효돈분, 무톱밥발효돈분 및 액상발효돈분을 100,200,400kgN/ha 수준으로 시용했을 때의 연구 결과는 다음과 같다.


This study was conducted to investigate the effects of the type and application level of swine manure on herbage productivity, efficiency of nitrogen utilization and environmental pollution by the leaching of nitrogen compounds in mixed grassland. The field experiment was carried out on established grassland sward growing on silt clay loam soil. Main plots were the types of swine manure, such as swine manure fermented with sawdust(SMFWS), swine manure fermented without sawdust(SMF) and swine slurry(SS), and mineral fertilizer(Urea). Subplots were the application levels of swine manure, such as 100, 200 and 400 kgN/ha,
