What should we pay attention to when using potassium sulfate? Please give instructions that potassium sulfate is a kind of potash fertilizer with high quality and high potassium content. Potassium sulfate is a white crystal, and the K2O content is generally between 50% and 52%. It is soluble in water, has low hygroscopicity and is not easy to caking, and its physical properties are better than those of potassium chloride. Potassium sulfate is widely used in all kinds of soil and crops, especially taboo chlorides. Potassium sulfate can replace potassium chloride and become a good potash fertilizer. Three points should be paid attention to in the application of potassium sulfate: ⑴ can be used as base fertilizer. When potassium sulfate is used as base fertilizer in dry fields, the soil must be applied deeply to reduce the crystal fixation of potassium, facilitate the absorption of crop roots and improve the utilization rate of potassium fertilizer. ⑵ potassium sulfate can also be used as topdressing. Because potassium is less mobile in the soil, it should be concentrated in strips or holes in the soil layer with dense roots to promote absorption. ⑶ has a good effect on rape, violets and other cruciferous crops that need more sulfur, so it should be allocated and used first.
