Bioconversionof biomass residuefrom thecultivation of pea sprouts on spent Pleurotussajor-cajucompost employing Lumbricus rubellus

Vermicomposting is a green technology for the purpose of nutrient enrichment from a variety of organic waste products. In this study, saw dust-based spent mushroom compost (SMC), an organic waste and biomass residue, was used as a medium for the cultivation of pea sprouts. After harvesting the pea s...
