K2SO4, commonly referred to as sulfate of potash, or SOP. Sulfate of Potash Granular is a 0-0-50 white granule that provides 50% potash and 17% sulfur to crops.The fertilizer contains S and hence this becomes an ideal fertilizer to deliver a combination of Potash and S.
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.
