บทคัดย่อ

Utilization of bio-extract (BioEx) as microbial inoculum on composting process are widespread in Thailand, however, the information about bio-extract as microbial inoculum is sparingly available in literature. In addition, wastes from cassava plantation, particularly, leaves and stems, are recalcitrant for biodegradation due to their high lignocelluloses content. This study interested in the use of microbial inoculum from cassava leaves and stems bioextract on composting of cassava leaves and stems in the combination with cow manure and molasses. Inoculum concentrations employed were in the range of 0-15 % by weight (0 % (experiment 1), 5 % (experiment 2), 10 % (experiment 3) and 15 % (experiment 4)). The results showed that inoculums concentration had no effect on the increasing temperature as well as the pH change within the pile during composting. Inoculum addition affected total carbon loss (TC loss) and total nitrogen loss (TN loss) significantly during composting process of 203 days. Additionally, TC loss of approximately 64.8 % w/w in experiment 3 was significantly higher than those of the others (p<0.05). Moreover, the highest TN (3.41) and TN loss (23.62 %) were accomplished using 10 % BioEx inoculum; however, insignificantly different from that of experiment 4 (BioEx 15 %) (p>0.05).
