Abstract: Nitrogenous waste, poultry droppings is generated in huge amounts and cause serious hazards to the environment. In this experiment, poultry droppings (PD) amended with sugar cane pressmud (PM) and cow dung (CD) were used as substrate for exotic earthworm species Eudrilus eugeniae and Eisenia fetida to stabilize and standardize the recycling the nutrients on the basis of changes in humification process during experimentation. The humification process during worm unworked composting and vermicomposting was carried out and observed results were suggested that total humification process in the vermicompost produced by both species of earthworms E. eugeniae and E. fetida were significantly enhanced than initial substrate and worm unworked natural compost. Though, among the different treatments VT1, VT2 and VT3 treatments for E. eugeniae and VT6, VT7 and VT8 for E. fetida treatments showed significantly (p<0.05) higher level of total humic acid content (HA) and humification index (HI) and reduction of total fulvic acid (FA) and humic carbon content (HC) than other treatments of both worms and treatments without earthworms (WW11 to WW15).
