Hard Water 211

Specially designed to solve the challenges of hard water










Universol Hard Water 211 is developed for application in hard irrigation water, with high levels of bicarbonate. With an N:K ratio of 2:1, it is ideal for plants requiring high amounts of nitrogen during the early growth stage (e.g. foliar plants). Universol Hard Water 211 acidifies the irrigation water and neutralizes bicarbonate.

  • Contains all elements; NPK, magnesium and trace elements

  • Always the same composition thanks to stringent quality control

  • The pH of the soil remains stable as a result of the HCO3- buffering effect

  • Improves the quality of your irrigation water, by taking out bicarbonates

  • Dissolves entirely and quickly because of the special ingredients and the ‘Bright Solution System’
