Capacity of fly ash and organic additives to support adequate earthworm biomass for large scale vermicompost production
Journal Title: Journal of Research in Ecology - Year 2012, Vol 1, Issue 1
Abstract
To investigate the feasibility of utilization of vermiculture technology for large scale production of vermicompost from Fly Ash (FA) mixed with Press Mud (PM), Cow Dung (CD) and Crop Residue (CR) employing earthworms Eudrilus eugeniae and Lampito mauritii. Eight treatments namely FA alone (T1), 1 part FA: 1part CD (T2), 1 part FA: 1part PM (T3), FA: 1 part FA: 1part CR (T4), 1 part FA: 1part CD: 1part PM (T5), 1 part FA: 1part CD: 1part CR (T6), 1 part FA: 1part PM: 1part CR (T7) and 1 part FA: 1part CD: 1part PM: 1part CR (T8) were run under laboratory conditions. The growth and reproduction of earthworms in terms of biomass gain, cocoon and hatchlings production were measured at the end of experimentation. The data revealed that earthworms were unable to survive in 100% FA (T1) treatment. However, Maximum worm biomass was observed in T5 treatment than other treatments. Maximum cocoons and hatchlings production were also recorded in T5 treatment for both species of worms. This study clearly indicates that fly ash amended with pressmud and cow dung in 1:1:1 ratio had no adverse effect on the growth and reproduction of E.eugeniae and L.mauritii as well as large scale vermicompost production
