The Utilization of Mushroom Waste Substrate in Producing Vermicompost: The Decomposer Capacity of Lumbricus rubellus, Eisenia fetida and Eudrilus eugeniae

The objective of this study was to determine the capacity of , and earthworms in vermicompost production utilizing mushroom waste substrate based on weight; number and weight loss of earthworms; temperature; pH; moisture content of media; and C/N ratio. The results showed that, by using 42 g of , and earthworms, there was an increase in weight of earthworms and vermicompost by more than 300% and 75%, respectively. In general, these three species of earthworms were able to produce vermicompost in compliance with quality standards, showing C/N ratio lower than 20.
