1, see the packaging. Where qualified chemical fertilizers are produced by regular manufacturers, their packaging bags are usually marked with the product name, nutrient content, net weight, and origin etc.; false degraded fertilizers have rough packaging and high breakage rates; signs are incomplete or illegible, and sometimes Do not use Pinyin for Chinese characters to impersonate imported fertilizer. 2, see the price. As the saying goes: "Cheap without good goods." The price of fake fertilizers is generally lower than the price of similar high-quality fertilizers on the market. 3, see the variety. False deteriorating fertilizers are generally compound fertilizers, urea, superphosphate, liquid fertilizers, and foliar fertilizers. When buying such chemical fertilizers, special care must be taken; ammonium bicarbonate and other fertilizers rarely appear in the market as fakes. 4, look at the appearance. Different chemical fertilizers often have different appearance characteristics, such as ammonium bicarbonate is white, with a strong ammonia odor; urea, ammonium sulfate, ammonium nitrate, ammonium chloride are all white granular crystals; calcium carbonate is gray powder, there are Sour taste; Ca-Mg-P fertilizer is a gray-white powder, no odor; Potassium sulfate is a white powder crystal, no odor; Diammonium phosphate is yellow-gray or iron-gray particles, the particle size is not uniform, and it is volatile in a humid environment, with ammonia taste. In addition, Ammonium Sulfate, Ammonium Nitrate, Ammonium Chloride and other ammonium nitrogen fertilizers and diammonium phosphate and other compound fertilizers containing ammonium nitrogen, placed on the palm of your hand, adding a small amount of hardwood ash, there is a clear smell of ammonia. If the fertiliser encountered is obviously inconsistent with its characteristics, it can be concluded that it is a fake deteriorating fertilizer.
