PURPOSE: A manufacturing method of fertilizer is provided to effectively extract water-soluble minerals included in bentonite by manufacturing an extracted solution by using bentonite particles. CONSTITUTION: A manufacturing method of fertilizer comprises the following steps: providing an extracted solution manufacturing device which contains an extraction tank(200) and a storage tank(100); filling the extraction tank with a plurality of bentonite particles(10); storing the extracted solution in the storage tank by extracting materials included in the bentonite; circulating the extracted solution in the storage tank to the extraction tank; and mixing bentonite powder with the extracted solution. The diameter of the bentonite particles within the extraction tank is 5-100mm. A ratio of the volume of the extraction tank to the storage tank is 1:2-1:5. The extracted solution comprises silicic acid, alumina, ferric oxide, calcium oxide, magnesium oxide, potassium oxide, and sodium oxide. |
