"Four Looks" is:
When looking at the business qualifications of chemical fertilizer operators, whether there are legal procedures for operating business licenses for chemical fertilizers. Try to choose a store or enterprise manufacturer that is legal, large-scale, and reputable.
Second, look at the product certification, fertilizer inspection form, and ask for proof of purchase and sales.
Third, look at the fertilizer label, distinguish the type and nature of the fertilizer; understand the nutrient content, use, usage and precautions of the fertilizer. The national standard GB18382-2001 (content requirements for fertilizer identification) stipulates that the fertilizer must indicate the total nutrient (only N+P2O5+K2O) content, and no medium or trace elements or organic matter should be added to the total nutrients. However, it was found that there are still companies that add medium, trace elements or organic matter to the total nutrients to deceive consumers. In this case, the peasant brothers should pay attention. It should also be noted that when the compound fertilizer contains chlorine or chloride ions, it should not be used or used with caution in tobacco and other chlorine-repellent crops. It should be used properly on the seedlings to avoid the burning of seedlings. Fertilizers containing nitrate-containing nitrogen should be used with caution in paddy fields to avoid loss of nitrate nitrogen.
Fourth, see if the fertilizer company has gone through the relevant formalities. For example, foliar fertilizers and microbial fertilizers must go through the fertilizer registration certificate of the Ministry of Agriculture; compound fertilizers, organic fertilizers, etc. must apply for provincial fertilizer registration certificates, and compound fertilizers must also apply for production licenses.
"Four Don't" is:
Don't try to make small and cheap, regardless of quality, buy fake and inferior fertilizers, so as not to cause unnecessary losses. At present, the qualified rate of phosphate fertilizer and compound fertilizer is relatively low, especially potassium dihydrogen phosphate. The logo is confusing and there are many counterfeit products. Pay more attention when purchasing.
Second, we must look at "big" and not "small." Some products are marked on the packaging with a large name on the packaging, and in order to cope with the inspection by the supervision department, the substance is marked in small letters. If large characters are used to mark "Russia" in a prominent position, "stake" and "raw materials" are marked with small characters to make people mistakenly recognize imported products; others are marked "potassium sulfate type" in a prominent position, inconspicuous Mark "chlorine" to achieve the purpose of disturbing audiovisual.
Third, don't be confused by new concepts. Some products are based on high-tech scorpions. Make a big fuss on the packaging, labeled with "bio", "activation", "green" and other high-tech names, which are actually general products.
4. Don't think that you are "unlucky." If fake fertilizers or fertilizers are found in use, they should be reported to the local agricultural authorities, technical supervision departments, industrial and commercial departments, and consumer associations in a timely manner.
