Fertilizer supplier These are substances that provide plants with one or more essential nutrients, improve soil properties, and enhance soil fertility. They constitute one of the material foundations of agricultural production. The main types include ammonium phosphate fertilizers, water-soluble fertilizers rich in macronutrients, fertilizers containing meso-elements, biofertilizers, organic fertilizers, and multi-dimensional, field-energy-concentrated organic fertilizers. Next, let’s join our agricultural magnesium nitrate expert to learn how to distinguish between genuine and counterfeit urea—a common fertilizer offered by chemical fertilizer suppliers!
Take a close look: Genuine urea is a translucent, five-colored granule of uniform size. If the surface of the granules appears too bright or too dark, or if they exhibit noticeable reflections, it’s possible that impurities have been mixed in. Therefore, be cautious when purchasing urea to avoid counterfeit products.
Second check: Inspect the production batch number and seal on the packaging. Generally, the production batch number on genuine urea packaging is clear and features a machine-sealed closure with folds on both sides. On counterfeit urea packaging, the production batch number is either unclear or absent altogether; most such packages have single-line, hand-sealed closures.
Third point: The difference between the actual weight of urea produced by reputable manufacturers and its standard weight generally stays within 1%. In contrast, urea containing counterfeit products deviates significantly from the standard weight.
Four touches: Genuine urea granules are uniformly sized and don't easily clump together, making them feel smoother to the touch. In contrast, when you touch fake urea with your hand, it feels burning and stinging.
Five tests: Pure urea placed on glowing red charcoal melts rapidly, emitting white smoke and an ammonia-like odor. If vigorous combustion occurs on the charcoal, accompanied by intense light and a “hissing” sound, or if the urea fails to melt completely, then it must contain impurities.
Six observations: Under normal circumstances, urea from reputable manufacturers has no volatile odor; an ammonia smell only develops when the urea becomes damp or exposed to high temperatures. If a strong volatile odor is present under normal conditions, it indicates that the urea contains impurities.
