What it is / When to use

Iron chelate for high-pH and calcareous soils

EDDHA-Fe 6% is a fully water-soluble iron chelate, C18H16N2O6FeNa, carrying Fe 5.8-6.5% and a 4.8% ortho-ortho isomer at pH 7-9. RunziChem exports it as the reference correction for lime-induced iron chlorosis where ferrous sulphate and EDTA-Fe break down on calcareous soils.

  • What it is Iron EDDHA chelate, C18H16N2O6FeNa, MW 435.2, reddish-brown to near-black granular powder.
  • When to use Use it to correct iron chlorosis on high-pH, calcareous soils (pH 7-9); for neutral to acidic soils compare EDTA-Fe 13%.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

Applications

Where EDDHA-Fe 6% fits

Confirm crop, rate, compatibility, and local label requirements before application.

Iron chlorosis correction

Corrects lime-induced iron chlorosis (leaf yellowing) where ferrous sulphate and EDTA-Fe fail.

High-pH, calcareous soils

The 4.8% ortho-ortho isomer keeps iron plant-available across pH 7-9 alkaline and calcareous soils.

Drip & fertigation

Fully water-soluble for drip irrigation and fertigation, plus soil drench and root-zone feeding.

Foliar green-up

Applied as a foliar spray to green up chlorotic new growth on iron-deficient crops.

Crops

Suited to fruit trees, citrus, grapevines, vegetables, and ornamentals prone to iron deficiency.

Compare with EDTA-Fe

For neutral to acidic soils, compare EDTA-Fe 13%, which carries more iron per ton at lower cost.

Packaging & Documents

Buyer FAQ

EDDHA-Fe 6% questions

When should I use EDDHA-Fe instead of EDTA-Fe or ferrous sulphate?
Choose EDDHA-Fe 6% when soils are high-pH or calcareous, roughly pH 7-9, where its ortho-ortho isomer (4.8%) keeps iron plant-available after EDTA-Fe and ferrous sulphate break down. For neutral to mildly acidic soils, EDTA-Fe 13% carries more iron per ton at lower cost and is usually sufficient.
What does the ortho-ortho (o-o) isomer content mean for EDDHA-Fe quality?
The ortho-ortho isomer is the fraction of EDDHA-Fe that stays stable and chelated at high pH, so a higher o-o value means more durable iron correction. RunziChem EDDHA-Fe 6% carries a typical 4.8% ortho-ortho isomer; the exact o-o percentage for your lot is confirmed on the batch COA.
How is EDDHA-Fe 6% applied on crops?
EDDHA-Fe 6% is fully water-soluble and is applied by drip irrigation and fertigation, soil drench and root-zone feeding, or foliar spray to green up chlorotic new growth. It suits fruit trees, citrus, grapevines, vegetables, and ornamentals prone to iron deficiency on calcareous soils.
Are the iron and ortho-ortho values guaranteed?
No. The figures shown for EDDHA-Fe 6%, such as Fe 5.8-6.5% and the 4.8% ortho-ortho isomer, are typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final iron content, ortho-ortho isomer, pH, and appearance for the lot you receive.
