The present invention relates to a manufacturing method of a water-soluble granular fertilizer. More particularly, the method comprises: a raw material mixing step for mixing ammonium phosphate, urea, ammonium sulfate, potassium chloride, potassium phosphate, and potassium sulfate; an additive mixing step for mixing an additive to the mixture mixed through the raw material mixing step; and a molding step to mold the mixture mixed with the additive through the additive mixing step. The water-soluble granular fertilizer is manufactured through the processes above without using a coarsening agent and an extending agent, and thus shows effects of rapidly being dissolved in water. |
