There are ways to improve the simple and false compound fertilizer

Compound fertilizer is one of the main fertilizer varieties used by farmers' friends. It is made by physical processing, and there are at least two kinds of fertilizers in the three nutrients of nitrogen, phosphorus and potassium. Because compound fertilizer can be formulated and fertilized according to different crops and different soils, it can increase production and income more than single fertilizers such as potassium fertilizer and phosphate fertilizer, so it is very popular among farmers.
Through comparative experiments and market research, it is found that the nutrient content of some compound fertilizer products is not up to standard, and some even deliberately put calcium, magnesium, sulfur, etc., which are not nutrient content, into the nutrient content, and the false indication reaches 40% or even 50. More than %; the water exceeds the standard, which makes the fertilizer granularity not strong, and it is easy to break when used. There are two kinds of potassium in the compound fertilizer, one is potassium chloride and the other is potassium sulfate. Potassium chloride contains chlorine, and chlorine crops (such as grapes, potatoes, tobacco, beets) should not be applied. National standards require that the chlorine content of fertilizer products must be marked on the outer packaging, but some manufacturers in order to increase the potassium content, the potassium chloride with lower market price acts as potassium sulfate, but the package does not intentionally label the chloride ion, the farmers are in use. Misuse of chlorine-sensitive crops can cause serious consequences such as reduced production.
Remind the vast number of rural consumers that when purchasing fertilizer, they must go to a distribution network of agricultural products with fixed places, legal procedures, complete licenses, and large-scale reputation. Here are six easy ways to identify compound fertilizers.
Look. A look at the packaging logo. Whether the fertilizer is double-layered, whether the outer packaging bag is marked with the trademark, production license number, agricultural use registration number, standard code, total nutrient content and nutrient distribution type, and the name and address of the production enterprise. Second, look at the logo content. The total nutrient content of compound fertilizer must be the sum of nitrogen, phosphorus and potassium. The content of other elements cannot be included in the total nutrient content, otherwise it will mislead farmers. The total nutrient content of nitrogen, phosphorus, potassium ternary or binary compound fertilizer shall not be less than 25%, otherwise it is a substandard product. Third, look at the fertilizer in the bag. The compound fertilizer has various colors such as black gray, gray, milky white, pink and light yellow due to different raw materials and production processes. Its appearance is small spherical shape, smooth surface, uniform particles, no obvious powder and mechanical impurities. If it is easy to agglomerate, the moisture content is too high.
smell. Compound fertilizers generally have no odor (except organic-inorganic compound fertilizers), and if they have odor, they are inferior compound fertilizers.
taste. You can take a small amount of compound fertilizer to taste at the time of purchase. If there is no salty bitterness, it is a fake product.
touch. Grab the compound fertilizer with half a hand, leave a layer of grayish white powder on the hand and have a good feeling of stickiness; the inferior compound fertilizer has no stickiness, and there is no white crystal in the grain.
Dissolved. When placed in water, the particles will slowly dissolve into a paste. The fertilizer granules are not dissolved in the water for a long time, and the quality of the fertilizer may have certain problems.
burn. It is burned on an open flame, nitrogen has an ammonia odor, potassium has a yellow flame, and the ammonia smell is thicker. The yellower yellow flame is higher in content, and vice versa is a poor quality compound fertilizer.
