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, seed fertilizer and top dressing. The base fertilizer is generally 10-12.5 kg, the fertilization amount is 1.5-2.5 kg, and the foliar spray fertilizer is 0.5%-2%. 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 the sand with poor fertilizer retention capacity. Generally, it is best applied to potassium plants such as potatoes and melons. Wide range of use, large dosage.
The appearance of potassium chloride is white or light yellow crystal, sometimes containing iron salts in red. Soluble in water, it is a high concentration of quick-acting potash. It can be used as base fertilizer and topdressing. The amount of base fertilizer is 8-10 kg, and the amount of fertilizer is 5-7. 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 grapes, potatoes, tobacco and other crops to avoid "chlorine damage".
To correctly distinguish and use these two kinds of fertilizers, it should be noted that when purchasing potassium fertilizer, the first thing to look at is whether the appearance meets the above explanation; the second is to see the bag marking implementation standard, the potassium sulfate implementation of HG/T3279-1990 issued by the Ministry of Chemical Industry, chlorine The national standard GB6549-86 implemented by potassium, and the third can not simply consider the price, mainly depends on its nutrient content.
