Potassium sulfate (also known as SOP) has better anti-caking performance, and its influence on soil pH is neutral. For agricultural products that need more sulfur nutrition, it is an effective fertilizer. Crops that need more sulfur nutrition include cabbage, onion, cruciferous plants, all oilseed crops and most tropical and temperate fruit crops. Potassium sulfate can not only supplement potassium in soil like potassium chloride, but also supplement zinc, boron and other elements, which can adjust the chemical structure of soil and enhance the fertility of soil.
