The quality of water has a major influence on the effectiveness of fertilizers. These tips and tricks from our technical advisors will help you optimize fertilization and irrigation water. 

  • Contact ICL Lab Services for an irrigation water analysis (minimum once a year)
  • Review your analysis with your regional ICL Territory Manager
  • The most common parameters used for determining irrigation water quality are acidity (pH), electrical conductivity (EC) and hardness (Ca-, Mg-bicarbonate), but look at the other elements in water as well
  • Determine, together with your ICL Territory Manager, the need for measures to improve the quality of the water
  • Take into account the differences in water hardness and pH buffering capabilities between different types of irrigation water (e.g., rainwater vs. well water) 
  • If the water is too hard, it may be necessary to decrease the pH in the water by acidifying
  • Soft water may contain low concentrations of calcium. Adjust tank composition accordingly and add calcium
  • Match irrigation to water quality, weather conditions, and plant needs at all times
