High purity, soluble, technical potassium sulphate. Free from harmful elements for crops such as chlorine and sodium or other impurities that reduce the solubility of the product. These properties make this product the only alternative potassium source to potassium nitrate. It is advisable to use Hydrokali 51 when potassium is required during the maturation phase of the crop, avoiding the unwanted effects caused by Nitrogen.
The acid nature of the product makes it suitable for calcareous and alkaline soils. The application of sulphur helps important protein synthesis (cystine, cysteine, methionine) and plays an important role in the development of plant-friendly soil bacteria.
