Abstract
In this study, the biochemical methane potentials of different agricultural residues produced from agricultural plastic greenhouse were determined. Additionally, ensiling storage practice was applied on agricultural residues for its effect on biogas production. Agricultural residues of cabbage, strawberry, tomato, cucumber, and oriental melon were selected as sample. The methane potential and biodegradability of agricultural residues ranged from 149~286 mL-$CH_4/g$-VS, 27~48% (by vol.), respectively and methane production was in order of cabbage > oriental melon > strawberry ${\approx}$ cucumber > tomato. Ensiling caused difference in methane production in a range of -11~36% (by vol.) per VS compared with raw material. An increase in methane potential was presumably linked to the organic acid accumulation, cellulose degradation and decrease in methane potential was due to chemical composition change, ammonia accumulation during the storage process.
