Potassium Thiosulfate is a clear, chloride free source of potassium and sulfur. These vital nutrients are supplied in the highly soluble form as potassium thiosulfate, making them readily available for plant uptake. Potassium Thiosulfate can be blended with N and P banded starter fertilizers to correct both potassium and sulfur deficiencies. Potassium Thiosulfate may also be applied as a foliar fertilizer, injected through irrigation systems, or Y-dropped providing potassium when crop demand is often the highest.
