Abstract

The study was executed to evaluate the agricultural utilization of phyllite as composting bulking agent in pig manure. The effects of the composted pig manure were verified by adopting the mixture of 10% phyllite and 20% saw dust(PSPC 10) and 20% phyllite and 10% saw dust(PSPC 20). The pig manure mixed with 30% saw dust was used as a control(PSC). However C/N ratio was very decreased because humus was rapidly progressed at PSPC 20 plot during the composting. Also, $NH_4{^+}-N$, $NO_3{^-}-N$, pH and EC were quickly changed from after one week and CEC was the highest as $92cmol_c/kg$. And Total-N was hardly changed during the composting but total carbon was rapidly declined as processing compost. Therefore, the phyllite has positively showed comparing with others in the street as compost bulking agent and go ahead, it is concerned that this material should have to research and investigating, constantly.

본 연구는 phyllite의 돈분 퇴비화 과정 중 수분조절제로서의 활용 가치를 평가하기 위해 수행되였다. phyllite에 대한 수분조절제로서의 평가를 위해 톱밥을 이용한 돈분퇴비구(PSC)를 대조구로 하였다. Phyllite 10%와 톱밥 20%를 처리한 퇴비구(PSPC10)와 phyllite 20%와 톱밥 10%를 처리한 퇴비구(PSPC20)에서의 결과 20%의 phyllite를 첨가한 처리구에서는 부숙이 빠르게 진행되었지만, 상대적인 유기물의 감소로 인한 C/N비가 매우 낮았다. 따라서 phyllite는 현재 퇴비화에서 사용되고 있는 재료와 비교하여 비교적 양호한 결과를 나타내었으며 앞으로도 좀 더 다양한 농업적 자재로서의 활용연구가 이루어져야 할 것이다.
