Abstract
Maturity indices of vermicomposted cattle manure were studied in an optimal moisture condition at 20℃ and with inoculation of Eisenia foetida in laboratory.The variations of biological and chemical parameters of cattle manure during vermicomposting and their correlation coefficients indicated that GI,URE,NH4+-N and NO3--N/NH4+-N were the priority selected maturity indices for vermicomposted cattle manure,NO3--N and APH common ones,and INV,WSC,WSN and VS unsuitable maturity ones.
