Fertilizers are an important source of nutrition for our crops, so the quality of the fertilizer is important to us. Well, many fertilizers on the market are now mixed. Therefore, this requires us to take a method to identify.
The following methods can be used to identify the quality of the compound fertilizer. First, look at the high-quality compound fertilizer particles, no size lumps, less powder, visible red fine potassium fertilizer particles, or white urea particles. The second is cockroach, hand-mixed compound fertilizer, leaving a layer of gray powder on the hand, and a sticky compound for high-quality compound fertilizer. The third is to burn, take a little compound fertilizer and put it on the iron skin and put it on the open flame to burn. There is ammonia smell indicating nitrogen, and a purple flame indicates potassium. The stronger the ammonia smell, the longer the purple flame is the high quality compound fertilizer. On the contrary, it is inferior. The fourth is dissolved, the high-quality compound fertilizer will dissolve in the water, even if there is a small amount of precipitated powder, it is fine.
