The present invention relates to an amino acid liquid fertilizer using various marine waste, and a preparation method thereof, and more specifically, to a preparation method of an environmentally friendly amino acid liquid fertilizer using marine waste comprising: the freezing step of putting marine waste in a container to freeze the marine waste; the crushing and pulverizing step of crushing the frozen marine waste went through the freezing step and pulverized the crushed frozen marine to obtain the paste state of the pulverized product; the liquefaction step of injecting the paste state of the pulverized product went through the crushing and pulverizing step into a fermentation tank, adding a protease and water, heating the same in a heated bath at 35-60 ?, and first stirring the obtained solution at 100-120 rpm for 15-20 hours to obtain a liquefied pulverized solution; the fermentation step of second stirring the pulverized solution went through the liquefaction step at 40-80 rpm for 10-15 hours to mature and ferment the same; the filtration step of filtering the pulverized solution went through the fermentation step to obtain a filtrate; and the dissolving step of transferring the filtrate went through the filtration step to a tank attached with a stirrer, and adding one or more substances of nitrogen (N), phosphorus (P), potassium (K), boron (B), zinc (Zn), iron (Fe), magnesia (Mg), molybdenum (Mo), manganese (Mn) to dissolve the same, and an amino acid liquid fertilizer prepared thereby. According to the present invention, it is possible to treat marine waste, which is cheap material, by a simple process within a short period of time through a biological method without generation of odor and to improve conservation stability of a prepared amino acid liquid fertilizer. |
