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 to be deceived, not only causing direct economic losses, but also affecting agricultural production when delaying farming.
Look at the packaging: Where the qualified chemical fertilizer produced by the regular manufacturer, the packaging name is generally marked with Chinese characters, nutrients and their contents, net weight, origin, etc.; fake deterioration of fertilizer packaging is rough, high damage rate, incomplete signs or blurred writing In the Qing Dynasty, sometimes Chinese characters are not used in pinyin to pretend to be imported fertilizer.
Look at the price: As the saying goes: "Cheap is not good." The price of fake deterioration fertilizer is generally lower than the price of similar high-quality fertilizer on the market.
Look at the variety: fake deterioration of fertilizer is generally based on compound fertilizer (such as diammonium phosphate), urea, superphosphate and liquid fertilizer, foliar fertilizer, etc., in the purchase of such fertilizers, pay special attention.
Look at the appearance: different chemical fertilizers often have different appearance traits, such as ammonium bicarbonate is white, with strong ammonia odor; urea, ammonium sulfate, ammonium nitrate, ammonium chloride are white granular crystals; superphosphate is grayish white Powder, has a sour taste; three-material superphosphate is blue-gray, the particles are large and uniform, no odor; calcium magnesium phosphate is gray-white powder, no odor; potassium sulfate is white powder crystal, no odor; diammonium phosphate is yellow Gray or iron-gray particles, uneven particle size, volatile in a humid environment, and ammonia. 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.
