Potassium sulfate is a small crystal-like, white-colored fertilizer obtained through the reaction of potassium compounds with sulfuric acid. It has a high useful potassium content, containing 50% K2O. Potassium sulfate, being completely soluble in water, can be applied to the soil through both traditional and drip/irrigation methods, and also to the leaves using a sprayer. Its physical properties are superior to those of other potassium fertilizers. It is an ideal fertilizer for conditions where potassium chloride cannot be used due to its effect on sensitive plants or where there is a sulfur deficiency in the soil. It is more effective in soils with high lime content and high pH. This fertilizer is also used as a potassium source in the blending of compound fertilizers.
