Abstract
A method of producing organic fertilizer by using fish as raw material. The method comprises the steps of boiling the fish to prepare a stock, removing solids and oil contents from the stock to obtain a stock solution, thereafter treating the stock solution in a decomposition tank for enzyme decomposition, and filtering an enzyme-decomposed stock solution to form a clarified liquid. The clarified liquid can be used as a fertilizer as is or further condensed or dried into organic fertilizer without unnecessary components.
