METHOD FOR PRODUCING SEEDING AGENT

Provided is a method for producing a seeding agent containing a variety of and a large amount of effective microorganisms, from a raw material containing organic waste, at low cost. The method is characterized in that it comprises a fermentation step, a first drying substep and a second drying substep. The fermentation step is configured to aerobically ferment a raw material comprising organic waste and an auxiliary material. The first drying substep is a process of drying the fermented raw material after being subjected to the fermentation step, until a water content thereof becomes a value falling within a first range which is less than that as measured just after completion of the fermentation step. The second drying substep is a process of further drying the dried raw material after being subjected to the first drying substep, until a water content thereof becomes a value falling within a second range which is less than a lower limit of the first range, within a period of time which is less than a period of time required for the first drying substep.
