An Overview of Compost Maturity during Solid Composting
in Mixture of Dairy Manure and Crop Residues

Ji Hyung HONG, Juzo MATSUDA and Yoshinori IKEUCHI

ABSTRACT

    Moisture content and C/N ratio become a dominant factor in stabilizing compost. Well matured compost can be obtained by the temperature in compost before curing process ranged from 65 to 70 centigrade or more, the moisture content of a cured compost as between 45 and 50 percent for screening of bulking agent and handling without difficulty, and the C/N ratio of it as 20 or less. In order to maintain the moisture of the fresh compost around 50 percent and C/N ratio of it as less than 30 for a higher degree of curing, it was apparently necessary to control the moisture and to measure the C/N ratio for the selection of compost bulking agents.
