Nitrogen fertilizer
In the market, ammonium nitrate and polyol are generally used to impersonate farmers. When purchasing, they can be identified by the following methods: First, the appearance. Urea, ammonium nitrate and polyols are all white, odorless particles. The surface of the urea does not emit light; the surface of the ammonium nitrate particles is bright and has obvious reflection; the polyol white has no bright color and reflection. The second is the feel. The urea is smooth, loose and has no moist feeling; the ammonium nitrate is smooth but has a moist feeling; the polyol is loose, not too smooth, and has no moist feeling. The third is fire. Urea can be burnt on red charcoal or iron flakes, it can burn white smoke, and it has nitrogen odor; ammonium nitrate burns intensely, emits strong light, emits white smoke and is accompanied by the sound of "squeaky"; The alcohol is dispersed and burned without nitrogen odor.
Phosphate fertilizer
Unscrupulous traders in the market generally use phosphate gypsum, calcium magnesium phosphate fertilizer and waste cement slag as phosphate fertilizer, which can be identified by the following methods: First, the appearance. The true phosphate fertilizer is dark gray, grayish white or light gray loose powder with sour taste; the phosphogypsum is grayish white hexagonal or mixed powder, and has no acidity; the calcium magnesium phosphate fertilizer is similar in color to the phosphate fertilizer, and the shape is glassy fine or fine grain. It has no sour taste; the waste cement residue is gray powder, dull, has more hard materials, and has no sour taste. The second is the feel. Phosphate fertilizer is heavy, hairy but not frivolous; the phosphogypsum texture is light, hairy and relatively dry; waste cement slag is heavier than phosphorus fertilizer, not greasy, not cotton and hard. The third is water soluble. The phosphate fertilizer is partially soluble in water; the phosphogypsum is completely soluble in water; the waste cement slag is slurried after being dissolved in water and can be re-solidified.
Potash
One is the taste: Potassium has a spicy feeling on the tip of the tongue. The second is fire: Potassium fertilizer is placed on the iron piece and has a beating and popping sound. If it can burn, melt or emit white smoke and have a nitrogen odor, it is nitrogen fertilizer.
Finally, the farmers are reminded that when buying fertilizers , don't buy fertilizers that are sold by small vendors who run in the village . They must go to the qualified regular door to buy. Before buying, pay attention to whether the fertilizer packaging meets the requirements (production address, telephone number, Content, etc.), whether the three certificates are complete (production license, fertilizer registration certificate, product certificate), and ask for purchase invoice.
