Influence of earthworm( Pheretima guillelmi) on soil microbial biomass,and active biomass was studied Earthworm treatment(soil to earthworm ratio=5∶1)reduced soil total microbial biomass while the active microbial biomass and fungal to bacterial ration were not significantly affected The earthworm treatment enhanced release of microbially immobilised nutrients,and resulted a rejuvenation of microbial population,and an increase of microbial qCO 2 quotient and cellulolytic activity The influence of eart...
