•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 with open drainage, Ultrasol® SOP is applied to raise the EC level (salinity) in the nutrient solution.
