4 ways to identify true and false fertilizers

When farmers are busy preparing for farming, farmers’ friends start to buy fertilizers. In order to reduce the losses caused by fake fertilizers, several methods for identifying fake fertilizers are introduced. 1, look at the appearance: (1) look at the packaging. The product name, nutrient content, grade, trademark, net weight, standard code, factory name, factory address, production license number, registration certificate number, etc. should be indicated on the real fertilizer package. The fake fertilizers are incomplete and the packaging is rough. (2) Fertilizer color: All kinds of fertilizers have their special colors. For example, potassium fertilizer is white; phosphate fertilizer is mostly dark gray; nitrogen fertilizer is almost all white except carbon and ammonia, and some are slightly yellowish brown or light blue. 2. Touch the fertilizer. Put the fertilizer on the palm of your hand, hold it firmly or press it to rotate it, and judge the fertilizer according to the hand feeling. Using this method, it is more effective to distinguish the diammonium in the United States. Grab a handful of diammonium and hold it several times. Genuine. 3. Smell the smell. Simply judge by the special smell of the fertilizer. For example, ammonium bicarbonate has a strong odor; ammonium sulfate is slightly sour; superphosphate has a sour taste, and the smell of fake fertilizer is not obvious. 4. If it is difficult to distinguish the type of fertilizer from the surface observation, it can be distinguished according to the dissolution condition in the water. The fertilizer particles are sprinkled on the wet ground or wet with a small amount of water. After a period of time, it can be judged according to the dissolution of the fertilizer. Such as diammonium, potassium sulfate, potassium chloride can be completely dissolved; superphosphate, heavy superphosphate and other parts of the dissolution; compound fertilizer particles will be scattered, dissolved or a small amount of residue. The counterfeit fertilizer has poor solubility or does not dissolve at all (except for phosphate fertilizer).
