The present invention relates to a method for manufacturing liquid fertilizer by making natural minerals into organic materials wherein, more specifically, the liquid fertilizer is manufactured by converting natural minerals, which are inorganic minerals, into organic minerals by a chelate treatment to help activation of soil when the liquid fertilizer is supplied to the soil, and the rate of absorption of minerals into the human body can be increased by solving the problem where the rate of absorption of minerals into the human body is low when a person intakes crops cultivated on the soil since most existing fertilizers contain inorganic minerals. The method for manufacturing liquid fertilizer by making natural minerals into organic materials comprises the following steps : (a) preparing and mixing at least one kind of natural mineral powder among natural mordenite powder, Guiyang stone powder, tourmaline powder, rare earth mineral powder, and biotite powder; (b) preparing a solution having 10-20 wt% of a concentration by making ethylenediaminetetraacetic acid (EDTA) and distilled water react; (c) inserting the powder of step (a) and the solution of step (b) at a weight ratio of 3 : 7 and mixing the same at a rotation speed of 600 rpm at a reaction temperature of 35-40° C; (d) settling a result product of step (c); and (e) obtaining a supernatant after step (e).(S10) Powder preparing step(S20) Solution producing step(S30) Mixing step(S40) Settling step(S50) Obtaining stepCOPYRIGHT KIPO 2017
