6000 yuan of water-soluble fertilizer and 10,000 yuan of water-soluble fertilizer, where is the diff

Today the market price gap between the whole water-soluble fertilizer, some 6,000 yuan to buy a ton, while some per ton has reached more than 10,000 yuan, or even more than 20,000, the same is a whole water-soluble fertilizer, the price difference is so big it? According to industry sources, this is mainly related to the level of potassium sources and raw materials used.

　　Currently on the market all water-soluble fertilizer potassium sources are mainly three: potassium chloride type, potassium sulfate type, potassium nitrate and potassium dihydrogen phosphate type. Generally speaking, the price of fertilizers with potassium chloride type ******, followed by potassium sulfate type, ****** is potassium nitrate and potassium dihydrogen phosphate type. Because potassium sulfate type and potassium chloride type fertilizers contain a large number of sulfate ions and chloride ions, long-term application is likely to lead to a lack of calcium as a middle element in the crop, so it is easy to lead to fruit cracking, stunted growth points, yellow leaves, and even fruit umbilical rot and other diseases.

　　In addition, the long-term use of fertilizers containing sulfate ions and chloride ions will make the nitrate nitrogen absorption efficiency is greatly reduced, greenhouse soil salts will be enriched aggravation, soil crusting and not conducive to the growth of crop roots. And with potassium nitrate and potassium dihydrogen phosphate type of water-soluble fertilizers, these two types of any element can be absorbed and utilized by the crop, there will be no accumulation of salts and other symptoms mentioned above, the corresponding price is also ******.

　　Secondly, the level of raw materials used, high-quality water-soluble fertilizers are generally used in the production of food-grade and industrial-grade raw materials. Industrial-grade raw materials than agricultural-grade raw material prices per ton higher than a few thousand dollars, and in the fertilizer nutrient content, water solubility, absorption efficiency, heavy metal content, product stability and so on is significantly better than agricultural-grade raw materials. A lot of bad water-soluble fertilizers using agricultural-grade raw materials for production, low prices, quality is difficult to guarantee, and more unscrupulous manufacturers use the whole water-soluble articles, loaded with pure magnesium sulfate, amine sulfate, potassium nitrate and other raw materials profiteering.

　　Water soluble fertilizers, phosphorus source is very important, and also related to the price of fertilizer, which is why the price of potassium nitrate is much cheaper than the full water soluble fertilizers for important reasons *** After the formula on the basis of the technological advantages of each manufacturer, according to the different, good water-soluble fertilizers will be added to the combination of a number of additives to the water-soluble fertilizer formulations, the purpose of which is to further increase the utilization of fertilizers, improve crop yield and quality. But many unscrupulous merchants in the water-soluble fertilizer inside the addition of ****** and other substances, the pursuit of short-term effects, **** the ultimate victim is the farmers, in this regard, high-quality water-soluble fertilizers generally do not have obvious ammonia and pungent ****** taste, which is also very critical.
