At present, the peak seasons for fertilizers for various field crops are approaching. Topdressing is mainly supplemented with nitrogenous fertilizers and potash fertilizers. At present, agricultural potassium chloride in the fertilizer market has two colors, red and white. Many farmers' friends and dealers have asked in hotline telephone consultations. I used to use red potassium, and now I bought white potassium. How about the quality of white potassium? Some people even suspect that white potassium is false.
In fact, white potassium is as good as red potassium in terms of the content of active ingredients and the efficacy after application. In order to help consumers understand the causes of the differences in the color of the two potash fertilizers, we systematically describe the product characteristics and traits of agricultural KCl fertilizers, including color differences.
Agricultural Chloride Fertilizer Color The quality standards for agricultural potassium chloride in China stipulate that the product is white or red, depending on the method of extraction and recovery, and there is no difference in agricultural application. The color of products purchased by farmers' friends can be either white or red. It does not depend on color to distinguish between genuine and fake products. People have to ask why are there different colors of potassium chloride products, such as red and white? This is due to different manufacturing methods. Potassium chloride produced by the factory using dissolved crystallization and flotation processes is generally in the form of powder, which may be light yellow, brick red or white. In the past, potassium chloride produced in Canada was light-brick red. People used to call it "red potassium", and red was due to containing about 0.05% of iron and other metal oxides. In addition to red potassium, domestic and foreign potash companies also produce a lot of white potassium chloride products. There is no essential difference in actual application.
Shape and particle size Potassium chloride is in the form of small crystals or granules with particle sizes ranging from 0.8 to 4.7 mm or 0.6 to 3.3 mm. Particulate potassium chloride, mainly used for bulk blended fertilizer, is blended with the same granular grade of phosphorus diammonium, urea, etc. to produce blended fertilizer, also called BB fertilizer. Powdery fertilizers can be applied directly or mixed with other powdery nitrogen and phosphorus fertilizers, and then processed into a three-component compound fertilizer by secondary granulation using a pellet or extrusion method.
Potassium chloride content potassium chloride (K) 50% to 52%; potassium oxide (K2O) 60% to 63%, while chlorine 47.6%. In addition, it also contains small amounts of accessory components such as sodium, calcium, magnesium, bromine, and sulfate.
Hygroscopicity and agrochemical properties Potassium chloride is slightly hygroscopic and rarely cakes in the north. In the south, especially in the rainy season, the weather will seriously absorb moisture and start deliquescence, and it will agglomerate after a long time. Potassium chloride is readily soluble in water and is an available fertilizer, although it is chemically neutral in water. However, potassium chloride is a physiological acid fertilizer when applied to the soil.
Potassium is easily held by the soil colloidal particles and absorbed by the crop roots. Chlorine can not be absorbed by the soil rubber particles, and the root absorption of the crop is very low. The remaining chlorine can be washed by rain or irrigation water, and generally does not cause harm. However, if there is more residual chlorine, it will have an effect on the soil. In acidic soils, the acidity of the soil is increased, the solubility of aluminum and iron in the soil is increased, and the toxic effects of active aluminum are aggravated. It should be combined with organic fertilizer and lime. In the neutral and calcareous soils, the formation of calcium chloride, leaching down, will cause changes in soil physical properties or even deterioration, should be applied with calcium fertilizer and organic fertilizer application.
In short, as long as it is agricultural potassium chloride, white potassium is as good as red potassium. Potassium fertilizer, the true and false judge, just look at the color is not enough, and ultimately rely on laboratory solutions. When farmers buy fertilizer products, they must go to regular sales outlets to avoid being deceived. There is a saying that is right: "Nothing cheaper." Potash fertilizer or to pay attention to quality, look for the brand.
