Description
A fully water-soluble liquid fertilizer providing high concentrations of Potassium and Sulfur in the form of Potassium Thiosulfate (K₂S₂O₃) with very low Chlorine content. Thiosulfate sulfur gradually releases sulfuric acid, helping to acidify the root zone and unlock fixed micronutrients — This can support nutrient availability and help improve uptake of certain micronutrients—especially iron (Fe) and manganese (Mn)—when soil conditions reduce their availability.
