Abstract: Disclosed are a microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt and a method of preparing the same, which relate to the technical field of production of water-soluble fertilizers. The microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The microgranular water-soluble fertilizer product co-produced from potassium nitrate by tower melt has balanced and stable nutrients. The product is microgranular, has a smooth appearance, is less susceptible to agglomeration, is easy to be absorbed and utilized by crops, and contains a full range of nutrients. In addition, the product is produced by a process employing fully automatic dispensing equipment, which mainly integrates “dispensing, mixing and packaging” and is fully automated.
