Chelated Iron DTPA 11%


An essential micronutrient that supports many plant functions and without enough iron, leaves will begin to turn yellow/white in colour.

  • 100% water soluble
  • Enhances the production of chlorophyll, which is required for photosynthesis
  • Used to treat or prevent iron deficiencies in plants such as iron chlorosis
  • Stable in nutrient solutions up to pH 7.0
  • The addition of chelated iron is particularly important in aquaponic systems as they are typically iron deficient
