Ammonium sulphate or ammonium nitrate as a urea: Put the fertilizer in the palm of your hand, add a small amount of ash, and if it smells ammonia, it will prove to be ammonium sulphate or ammonium nitrate; otherwise, it is urea.
   Potassium sulphate is pretending to be ammonium nitrate or urea: Put the fertilizer on red charcoal or iron plate. If the fertilizer melts and emits white smoke and ammonia smell, it proves to be ammonium nitrate or urea. Among them, ammonium nitrate can be burned. It is urea that can't be burned; if there is no change and smell of fertilizer, but you can hear the cracking sound, it proves to be potassium sulfate. In addition, both ammonium nitrate and urea are granular crystals, while potassium sulfate is a powdery crystal. When the volume is the same, potassium sulfate is much heavier than ammonium nitrate and urea.
   "Three materials" pretending to be "diammonium": "three materials" is three-material superphosphate, also known as heavy superphosphate, referred to as heavy calcium, only one color of blue-gray, large and uniform particles, no Ammonia smell, while diammonium phosphate (farmers referred to as "diammonium") has yellowish gray, iron ash and other colors, the particle size is not uniform, and there is obvious ammonia odor when rubbed by hand.
