IRON EDDHA,
Reinvented.
Stable in Soil.
Available to Crops.
EDDHA-chelated iron remains available even in alkaline and calcareous soils, where conventional iron sources quickly lose efficiency.

What if iron
stayed available?
We made
iron last longer.
EDDHA protects iron from fixation in the soil, helping roots access the iron they need for healthy chlorophyll formation.

Dissolves with ease
A highly water-soluble formulation developed for fast, uniform preparation in irrigation and soil applications.
Stable at high pH
EDDHA keeps iron chelated and available under alkaline soil conditions where other iron forms become ineffective.
Precision in every dose
Homogeneous microgranules support consistent dissolution, uniform distribution and reliable application.
Ready for root uptake
Chelated iron moves through the root zone while remaining protected against soil fixation.
Iron Reaches the Leaf.
Green Returns.
Protected by EDDHA, iron stays available for root uptake and supports chlorophyll formation helping pale, yellowing leaves regain their healthy green colour.
