How to Identify the True or False of Compound Fertilizer?
In order to buy fertilizers of high quality and low price, farmers should have a certain knowledge of fertilizer identification, and understand laws and regulations to reduce unnecessary economic losses. Identification of genuine and fake fertilizers should proceed from four aspects:
1,Look at the packaging whether is marked with the three certificates (production license, fertilizer registration certificate, certificate of product) and standard number, indicating whether the manufacturer, the production location and contact telephone number. The label should indicate the total nutrient content and formula, such as total nitrogen marked in a marked position. The total nutrient on the label refers to the total amount of nitrogen, phosphorus, potassium, such as the inclusion of middle and trace elements, which is misleading and deceiving farmers. In addition, do not be exaggerated, false advertising and exquisite external packaging puzzle, to value the intrinsic quality of the product.
2, The manufacture of compound fertilizer has to go through a complex process, whether it is extrusion granulation or disc granulation, the particle is not only more uniform, but also has a certain strength. If the particle thickness uneven, color mixing with a large number of mottled, packaging dust more, hand pinch (rub) particles that scattered or block, and even dissolved 30 minutes later, there are still more residue. This kind of compound fertilizer is of poor quality, so don’t buy it.
3,Good smell of compound fertilizer composition is relatively stable, in the packaging will not decomposition and melting, so there will be no peculiar smell, ammonia flavor. If you find ammonia flavor, sour, indicating that the product quality is not pass, we must carefully buy.
4,Should establish brand consciousness, buy brand compound fertilizer. The formation of brand is the sublimation of enterprise image. The manufacturers of general brand products are larger in scale and standardized in management, and enterprises pay great attention to quality management and product inspection. Compared with non brand products, the product quality has more reliable guarantee. The more the manufacturer pays attention to the image, the better the product quality can be guaranteed.
