Spring is the peak season for sales and use of fertilizers. However, in recent years, fake degraded fertilizer has appeared in the market, causing many farmers' friends to be deceived, not only directly causing economic losses, but also affecting agricultural production when delaying farming. To this end, according to the characteristics of the fake deterioration fertilizer on the market, several simple identification methods are introduced.
1. Look at the packaging. For qualified fertilizers produced by regular manufacturers, the packaging name is usually marked with Chinese characters, nutrients and their contents, net weight, and origin. The fake deterioration of fat packaging is rough, the damage rate is high, the signs are incomplete or the writing is ambiguous, and sometimes the Chinese characters are used instead of pinyin to pretend to be imported fertilizer.
2, look at the price As the saying goes: "cheap no good goods." The price of fake deterioration fertilizer is generally significantly lower than the price of similar high-quality fertilizer on the market.
3, look at the variety of fake fertilizers are generally based on compound fertilizer (diammonium phosphate, etc.), urea, superphosphate and liquid fertilizer, foliar fertilizer, etc., in the purchase of such fertilizers, pay special attention. Fertilizers such as ammonium bicarbonate rarely produce fakes on the market.
4. Chemical fertilizers with different appearances often have different appearance traits. For example, ammonium bicarbonate is white and has a strong ammonia odor; urea, ammonium sulfate, ammonium nitrate and ammonium chloride are all white granular crystals; Gray-white powder with acid thorn; three-material superphosphate is blue-gray, large and uniform particles, no odor; calcium-magnesium phosphate is gray-white powder, no odor; potassium sulfate is white powder crystal, no odor; Yellow ash or iron gray granules, uneven particle size, volatile in humid environment, ammonia smell. In addition, ammonium nitrate such as ammonium sulfate, ammonium nitrate or ammonium chloride, and compound fertilizer containing ammonium nitrogen such as diammonium phosphate are obviously placed in the palm of the hand with a small amount of ash or alkali surface, lime surface, etc. Ammonia smell. If the fertilizer to be purchased is clearly inconsistent with its characteristics, it can be judged to be a fake deterioration fertilizer.
