Provided is a manufacturing method of a slow-releasing fertilizer. The manufacturing method of a slow-releasing fertilizer comprises: a raw material mixing step of forming a mixture of a nitrogen raw material, a phosphoric acid raw material, and a potassium raw material; a pulverizing step of pulverizing the mixture; and a molding step of forming a molded article by molding the mixture. The molding step adjusts the pressure of the mixture to 5-20 MPa, and the temperature of the mixture to 40-80°C. By adjusting the pressure and the temperature, slow-releasing substances are formed in the molded article. The slow-releasing fertilizer is environment-friendly, and can be manufactured through a simple process. |
