Buy fat keep in mind five words: see touch

Although the quality of fertilizers, especially nutrient content, is difficult to distinguish, if you remember the words “see, touch, smell, burn, and dissolve” when you buy fertilizer, you can reduce cheating and fooling. Look at the packaging. The product name, nutrient content, trademark, net weight, standard code, factory name, site, production license number, and fertilizer registration certificate number must be indicated on the packaging bag of commodity fertilizer. If the above-mentioned mark is not complete or incomplete, it may be fake fertilizer. Look at the seal. Special attention should be paid to the seals of the bags that have obvious traces of unsealing. This fertilizer may be adulterated. Look at the shape. Nitrogen fertilizer (except lime nitrogen) and potassium are mostly crystalline. Phosphate fertilizers are mostly amorphous or powdery amorphous, calcium magnesium phosphate fertilizers are powdery, and superphosphates are mostly porous blocks. Compound fertilizer particle size is relatively uniform, smooth surface, not easy to absorb moisture and agglomerate, fertilizer fertilizer particle size is uneven, rough, high humidity, easy to caking compound fertilizer can basically be determined to be false. Look at the colors. Different fertilizers have their own unique colors. Nitrogen fertilizers are mostly white except for lime nitrogen, some are slightly yellow-brown or light blue (except for the addition of other ingredients); potassium is white or slightly red, such as potassium dihydrogen phosphate is white; Phosphate fertilizer is mostly dark gray, such as superphosphate, calcium magnesium phosphate fertilizer is gray, diammonium phosphate brown, etc., farmers friends can make a broad distinction. Touch the fertilizer on the palm of your hand, hold it firmly or press it, and judge the fertilizer according to your hand. Using this method, to determine the United States more effective than the diammonium, grasping a handful of fertilizer grip several times, there is a "oily" feeling, the surface should be smooth in general should be true, dry, rough surface, mostly fake fertilizer. The sniffing is simply judged by the special odor of the fertilizer. For example, ammonium bicarbonate has a strong ammonia odor; ammonium sulfate has a slight sour taste; superphosphate has a sour taste, and counterfeit ones have no obvious odor; but superphosphate uses waste sulfuric acid in the production process, resulting in strong pungent The strange sour taste, this fertilizer is very toxic and can easily damage or burn the crop. The fertilizer sample is heated or burned to identify the fertilizer from the flame color, melting condition, smoke taste, residue condition, and the like. Nitrogen fertilizer, ammonium bicarbonate, directly decomposed, a lot of white smoke, a strong ammonia smell, no residue; ammonium chloride, direct decomposition or sublimation occurs a lot of white smoke, there is a strong ammonia and sour taste, no residue; urea , Can quickly melt, white smoke, put into the charcoal fire can burn, or take a glass sheet contact with white smoke, can see the glass sheet attached with a layer of white crystals; ammonium nitrate, but does not burn but melted and boiling, emerge There is ammonia-flavored smoke. Phosphate superphosphate, calcium magnesium phosphate fertilizer, phosphate rock powder, etc. did not change on red wood charcoal; bone powder quickly turned black and gave off char smell. Potassium potassium sulfate, potassium chloride, potassium magnesium sulfate, etc. did not change on the red charcoal, and gave off the sound of glutinous rice. The compound fertilizer combustion is closely related to its constituent raw materials. When its raw material contains ammonia nitrogen or amido ammonia nitrogen, strong ammonia odor will be released and there will be a large amount of residue. The dissolved fertilizer is dissolved in water. Take 1 gram of chemical fertilizer, put it in a clean glass tube and other vessels, add 10 milligrams of distilled water (or clean cold boiled water), and shake well to see if it dissolves. Nitrogen and potassium fertilizers are all dissolved. If turbid substances appear, they are fake and inferior fertilizers; superphosphate dissolves in water and there are residues; heavy superphosphate dissolves in water without residue or residue; and it dissolves in water but has large ammonia odor. It is ammonium bicarbonate; lime nitrogen is insoluble in water, bubbles are generated and there is a calcium carbide odor. It should be noted that although some of the fertilizers are true, the effective nutrient levels are not up to standard or very low. If this is the case, complaints should be submitted to the local fertilizer department, and some samples should be collected or retained, and fertilizer invoices should be purchased. The relevant bills provide necessary evidence for safeguarding their own legitimate rights and interests.
