• For the speedy, 'emergency' correction of iron deficiency when symptoms appear in a growing crop.
  • As an efficient iron source in hydroponics and fertigation systems particularly where low pH stock tanks are employed.
  • A high performance iron chelate to prevent and correct iron deficiency in most, horticultural and ornamental crops growing in high pH conditions. 
  • Especially recommended where the correction of iron deficiency is agronomically critical to achieve crop quality and profitability.


  • Contains 2.0 % water soluble iron chelated by EDDHSA, 95% of which is chelated by the ortho-ortho isomer.  This is the most biologically effective so correction of iron deficiency is quick and reliable.
  • Remains physically in solution at very low pH levels so ideal for adding to acidified "A" stock tanks.
  • High chemical stability therefore suitable for use in calcareous, high pH (up to 9.0 and above) soils.
  • Compatible with soluble phosphates thereby remaining effective in hydroponics and liquid feed systems.
  • Supplied as an easy to use liquid formulation. Can be measured volumetrically and disperses instantly.
