•A fully water-soluble crystalline potassium (K) and sulphur (S) source.
•Applied in fertigation of soil-grown crops during maturation phase, supplying part of the potassium without nitrogen.
•In hydroponic systems Ultrasol® SOP is applied in the first place as sulphate source for crops that require high amounts of sulphur.
