How to distinguish agricultural potassium sulfate from potassium chloride
With the rapid development of vegetable facility agriculture, the use of elemental potassium fertilizer is diversified, and the use of potassium sulfate compound fertilizer is on the rise. Correctly distinguishing between the use of potassium sulphate and potassium chloride is important for crop yield increase and quality improvement. The appearance of potassium sulfate is white crystal or colored crystals or particles. It is characterized by low moisture absorption, is not easy to agglomerate when stored, and is easily soluble in water. Applicable to all kinds of crops, can be used as base fertilizer, top dressing and top dressing. The base fertilizer is generally 10~12 kg, the amount of fertilizer is 5-7 kg, and the foliar spray is 0.5%~1%. Potassium is generally adsorbed by the soil and will not be lost. However, it is also necessary to adopt a “small amount of meals†on sand with poor fertilizer retention capacity. Generally, it is best applied to potassium plants such as potatoes and melons. The appearance of potassium chloride is white or light yellow crystal, and the iron salt is red. Soluble in water, it is a high concentration of quick-acting potash. It can be used as base fertilizer and top dressing. The amount of base fertilizer is 8~10 kg, the amount of fertilizer is 5-7 kg, and the foliar spray is 0.5%~1%. The scope of application is smaller than that of potassium sulfate. Special attention should be paid to the use of chlorine-sensitive crops such as watermelon, grape, and potato to avoid "chlorine damage." In addition, potassium chloride is not suitable for saline-alkaline soil, but chloride ions in potassium chloride promote photosynthesis and fiber formation, and are particularly suitable for application to fiber crops such as hemp. Differentiate and use these two kinds of fertilizers. When purchasing potassium fertilizer, the first thing to look at is whether the appearance meets the above requirements; the second is to see whether the implementation standard of the bag label implements the latest standard, the agricultural potassium sulfate implements the national standard GB20406-2006, and the national standard for potassium chloride implementation. GB6549-2011; the third can not simply look at the price, mainly analogous to its indicated nutrient content. The sales market of potash fertilizers is quite chaotic, and there are more illegal products. When farmers buy fertilizer, they should ask the dealers for the inspection report of the products. They can consult the fertilizer quality inspection department to avoid being deceived. Bio-potassium fertilizer is a kind of stimulation agent. The nutrient potassium content in the soil is not rich and it is not recommended.
