摘要

PURPOSE: A method for producing organic fertilizer using organic wastes and inorganic materials and a device used therefor are provided, therefore the organic fertilizer may not cause problems including over nitrogen provision and nutrient loss when applied to the soil. CONSTITUTION: The organic fertilizer producing method comprises the steps of: mixing 40 to 60 wt.% of food wastes, 15 to 35 wt.% of solids derived from the livestock feces and 5 to 45 wt.% of rotted inorganic materials; adjusting the water content in mixture to a certain level sufficient to carry out the aerobic fermentation; aerobically fermenting the mixture; and drying the fermented organic fertilizer.
