A method for manufacturing an organic slow-acting manure comprises a grinding step of drying dead fish or a powdered blood, a powdered bone, potassium chloride, natural gypsum, and dolomite for a certain time, and grinding the same; a hydrolysis step of liquefying the same into a macroelement-mixed liquid corresponding to nitrogen, phosphorus, and potassium by inducing hydrolysis; a depositing separation step of separating only a mixed liquid by depositing and removing impurities and a residue of hydrolysis; a soaking step of soaking anyone among the macroelement mixture and middle element mixture in the macroelement-mixed liquid; a particle forming step of mixing one or more caking additive liquids with the natural gypsum, dolomite, and potassium chloride powders in the grinding step to manufacturing grain-shaped particles; and a coating step of coating the external surface of any one among the particles formed by the caking additive and the soaked porous grains with a coating member with a vegetable oil and a binder mixed. |
