Evolution of humic material in different organic waste during vermicomposring using Perionyx ceylanensis

Author(s): M Muruganandham, S Angelina Glorita Parimala
Abstract: Humification during vermicomposting and composting of poultry droppings (PD), rice husk (RH) and sugarcane press mud (SPM) was investigated to reveal its correlation with humic composition. The aim of this study was PD was mixed with RH and SPM at various proportions to make different treatments (VCPT1-VCPT7) and kept for natural stabilization for 15 days and subsequently vermicomposted using native earthworm species Perionyx ceylanensis for a period of 75 days under laboratory conditions. Controls for the above treatment proportions were also included without the inoculation of worms (CT1-CT7). The humification process during composting and vermicomposting was carried out and the results were suggested that humic acid (HA) content in the vermicompost were significantly altered than initial substrate and natural compost. However, among the different vermicomposting and composting treatments VCPT2, VCPT3, VCPT6 and VCPT7 treatments showed significantly (p<0.05) higher level of humic acid (HA) and humification index (HI) and also reduction of fulvic acid (FA) and humic carbon (HC) content than other treatments. Hence, it was concluded that mixing of SPM and RH as mixing agent in appropriate quantity of PD creates suitable medium for humic material rich vermicompost production.
