The compost aging promoter is prepared by (A) mixing uniformly 1 part mixed bacteria with sawdust, ricehull and lime stone, which are added in a weight ratio of 4:5:1 ; (B) mixing 10 parts nutrient containing ZnSO47H2O, CuSO45H2O, FeSO47H2O, MgSO46H2O, KH2PO4 with above mixture from (A) ; (C) aging the mixture from (B) in the atmosphere at room temperature ; and (D) spraying over the mixture 1 part bacterial active material with a neutral pH, which is an aqueous solution containing 0.5% sugar, 0.05% NaCl, 0.02% MgSO4, 0.2% NH4Cl, 0.1% K2HPO4 and 0.1% KH2PO4, to increase the mixture temperature again, when the increased aging temperature begins to decrease.
