Coffee pulp is generated in huge amounts and cause serious hazards to the environment. In this experiment, coffee pulp (CP) with organic amendment sugare cane press mud (SPM) were used as substrate for native earthworm species P. ceylanensis and L. mauritii to stabilize and standardize the recycling technique on the basis of changes in humic composition during vermicomposting. The humification process during composting and vermicomposting was carried out and the results were suggested that humic acid content in the vermicompost of both species of worms were significantly altered than initial substrate and natural compost. However, among the different treatments PT4, PT5 and PT6 treatments for P. ceylanensis and LT10, LT11 and LT12 for L. mauritii treatments showed significantly (p<0.05) higher level of humic acid (HA) and humification index (HI) and reduction of fulvic acid (FA) and humic carbon (HC) content than other treatments of both worms and the same treatment without earthworms.
