초록

유기질비료 원료로서 가공계분은 질소, 인산, 칼리함량이 높고 본 연구는 수분조절제의 종류에 따라 다른 특성을 나타낸다. 본 연구는 수분조절제로서 톱밥과 피트모스를 혼합하여 발효한 두 종류의 가공계분을 혼합유기질비료의 원료로 이용하였을 때, 배합비율별 유기질비료의 이화학적 특성 및 작물생육 특성을 조사하였다. 톱밥이나 피트모스를 수분조절제로 첨가하여 발효시킨 가공계분이 함유된 혼합유기질비료는 가공계분이 10~30 % 함유된 혼합유기질비료에서 비료공정규격에 적합하였다. 톱밥 가공계분(PMCS)이나 피트모스 가공계분(PMCP)을 10~30 %정도 함유한 혼합유기질비료 처리구는 작물의 생육(건물중)이 증가하였다. 가공계분별 배합비율과 작물생육지수와 상관관계를 조사한 결과, PMCS 함유 혼합유기질비료와 작물의 생육 지수에서 영향을 미치지 않았고, PMCP 함유 혼합유기질비료의 시비는 작물의 생육 및 생산량이 증가하였다(P<0.05). 이들 결과를 종합할 때, 가공계분은 혼합유기질비료의 원료로 사용이 가능하였고, 혼합유기질비료 중 가공계분의 적정함유량은 10~30 %였으며, 시비에 의해 작물 생육이 증가하였다.

Poultry manure compost (PMC) as the organic fertilizer sources has a high nutrient content such as nitrogen, phosphate and potassium, and its properties been affected by bulking agent. This study was conducted to evaluate properties of mixed organic fertilizer (MOF) containing PMC composting with sawdust and peat moss as bulking agent, and to measure a characteristics of plant growth by their application. The MOF containing 10~30 % PMC had a coincidency with its guideline in Korea. As applied with MOF containing PMC composting with sawdust (PMCS) or MOF containing PMC composting with peat moss (PMCP), dry weight of plant was increased in MOF treatments blending with 10~30 % PMCS or 10~30 % PMCP. In correlation coefficient between blending ratio of PMC in MOFs and plant growth indexes, PMCS was not significantly different, but its PMCP a positive effect (P<0.05). These results indicated that PMC was able to blend about 10~30 % as mixed organic fertilizer source, and its application increased in plant growth.
