摘要
To provide a granular NK compound fertilizer that can be produced without adding an additive, whose production loss amount is small owing to high particle-hardness immediately after formation of secondary particles, and whose flowability does not decrease, which would be normally caused by particles degraded being solidified during storage.SOLUTION: A granular NK compound fertilizer of this invention is formed as secondary particles by integrating particles substantially composed of ammonium sulfate (particles A) and particles substantially composed of potassium chloride (particles B). In the granular NK compound fertilizer and a method of producing the NK compound fertilizer, the particles A have a particle diameter exceeding 0.25 mm and particles of 2 mm or less amount to 70 wt.% or more of the particles A; the particles B have a particle diameter exceeding 0.25 mm and particles of 2 mm or less amount to 60 wt.% of the particles B; and 50-80 wt.% of the ammonium sulfate and 50-20 wt.% of the potassium chloride are included in the compound fertilizer.SELECTED DRAWING: None
