In the peak season of spring ploughing and fertilizer sales, in order to prevent the purchase of counterfeit and shoddy products, according to the characteristics of fake degraded fertilizer on the market, several simple identification methods are introduced:
1. Look at the qualified chemical fertilizers produced by the regular manufacturers. The packaging bags generally indicate the product name, nutrients and their contents, net weight, and place of origin in Chinese characters. The fake deterioration of fat packaging is rough and the damage rate is high; the signs are incomplete or the writing is blurred. Unclear, sometimes it is not necessary to use pinyin in Chinese characters to impersonate 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 generally with compound fertilizer (such as diammonium Phosphate, etc.), urea, superphosphate and liquid fertilizer, foliar fertilizer, etc., in the purchase of such fertilizers, pay special attention to; ammonium bicarbonate, etc. Fertilizers rarely appear in 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 placed in the palm of your hand with a small amount of grass ash (or Alkali surface, lime surface). Ammonia smell. If the chemical fertilizer encountered is clearly inconsistent with its characteristics, it can be judged to be a fake deterioration fertilizer.
