ABSTRACT:
There is provided a method and apparatus for manufacturing organic fertilizers by fermentation of a mixture of livestock excrement with cellulose containing organic materials, said mixture containing thermophilic and aerobic microorganisms, which method comprises adjusting moisture content of said mixture to 25-75 wt %, cutting and kneading said mixture until the temperature thereof goes up to 40.degree. C.-90.degree. C. by the elevated pressure and friction caused by said cutting and kneading, thereby causing thermophilic organisms to be activated, followed by pulverizing the thus-treated mixture while contacting it with air, thereby causing the aerobic organisms to be activated.
