Abstract
For the evaluation of the quality of compost, the determination of C/N ratio is mandatory in Korea. Accordingly it is necessary to measure the total carbon content of compost for the quality control of composts. It is, however, not easy to measure the carbon content of compost. For practical purposes total carbon content of compost can be estimated from the total organic matter content, which is estimated by way of ignition loss. For this, it is necessary to establish the factor for conversion of organic matter into carbon. We studied the relationship between the organic matter content determined by ignition method and total carbon content measured by elemental analyzer using 160 compost sample collected from the markets. The relationship between the carbon content and organic matter in those composts was found to be "y(% carbon)=1.995+0.484%(% organic matter)"(
본 연구는 퇴비중의 유기물 함량으로부터 탄소함량을 구하기 위한 환산계수를 결정하기 위하여 수행하였다. 퇴비중의 유기물 함량은 회화법으로, 탄소함량은 원소 분석기를 사용하여 분석한 결과 유기물 함량과 탄소함량의 관계는 "탄소함량(%)=
