This study was carried out to evaluate the possibllity of composting from cow manure using earthworms. In order to rear earthworms safely and control moisture soil was used as conditioner. Fusarium oxysporum and Fusarium sp.1 were isolated from soil and two isolates of Bacillus sp. were selected as antagonists from earthworm casts. By rearing earthworm, C/N ratio was reduced by 40.9% and 41.9% after 28 days, reducing sugar was also decreased by 37.1% and 37.5%. On the other hand, reduction of C/N ratio in cow manure alone was 9.67% and reducing sugar was 12.01%, respectively. Bacillus sp. was apparently increased in earthworm casts than in ordinary soil. It seemed that the earthworm casts contained antibiotic subatance.
