Three burns. Take a small amount of compound fertilizer on the iron sheet, burn with open flame, ammonia smell indicates nitrogen, yellow flame indicates potassium, and the more ammonia smell, the yellower yellow flame, indicating the higher the nitrogen and potassium content, ie For high quality compound fertilizer.
Four smells. Compound fertilizers generally have no odor (except organic and inorganic compound fertilizers), and if they have odor, they are inferior compound fertilizers.
Five soluble. The high-quality compound fertilizer has good water solubility, and most of the soaked in water can be dissolved, even if there is a small amount of sediment, it is fine. The inferior compound fertilizer is hardly soluble in water, and the residue is rough and hard.
Six tastes. Potassium chloride is salty. It can be tasted with a small amount of compound fertilizer at the time of purchase. If it is not salty, it is a poor quality product.
