Application of Potassium Sulfate K2SO4

Instead of MOP, SOP can also be used in places where soil or irrigation water salt levels are high.

Good for crops that are more chloride-sensitive, such as berries and vines. SOP is a better choice where high chloride levels occur in irrigation water.

When potassium sulfate K2SO4 fertilizer is fertilized in the root, it is best to cover the soil deeply and use nitrogen fertilizer, phosphate fertilizer, and medium and trace elements at the same time, so as to achieve the effect of increasing production.
