Eurosolids Potassium Sulphate (SOP) Horticultural Grade is a highly pure Potassium fertilizer, which dissolves rapidly and completely. Our product is not sensitive to caking and is recommended during fruit or tuber development and up until maturation, and during coloring of fruits. The high level of Potassium in our formula plays an essential role in achieving higher quality yields.

  • Improves fruit quality, shelf life and increases plant drought resistance
  • Limits vegetative growth as of fruit setting
  • Developed for fertigation in open field and greenhouses. Also suitable for foliar application
