DANA Potassium Sulfate 0-0-50

Potassium sulfate is an excellent source of K nutrition for plants. The K portion of the K₂SO₄ is no different from other common potash fertilizers. However, it also supplies a valuable source of S, which protein synthesis and enzyme function require. Like K, S can also be too deficient for adequate plant growth. Further, Cl- additions should be avoided in certain soils and crops. In such cases, K₂SO₄ makes a very suitable K source. Potassium sulfate is only one-third as soluble as KCl, so it’s not as commonly dissolved for addition through irrigation water unless there’s a need for additional S. Several particle sizes are commonly available. Manufacturers produce fine particles (smaller than 0.015 mm) to make solutions for irrigation or foliar sprays, since they dissolve more rapidly. And growers find foliar spraying of K₂SO₄ a convenient way to apply additional K and S to plants, supplementing the nutrients taken up from the soil. However, leaf damage can occur if the concentration is too high
