EDTA FeNa

General Properties and Industrial Significance:

EDTA-FeNa (also written as Fe-EDTA or iron(III) EDTA sodium salt) is a chelated iron compound, where iron (Fe³⁺) is bound to EDTA (ethylenediaminetetraacetic acid) and stabilized with sodium (Na⁺) ions. It is a water-soluble and stable source of iron, especially useful in plant nutrition.
For soils with higher pH (alkaline), other chelates like Fe-DTPA or Fe-EDDHA are recommended instead.

Applications:

• Agriculture (Micronutrient Fertilizer):

1. Used to correct iron deficiency (chlorosis) in crops like citrus, grapes, soybeans, and ornamentals.

2. Iron is essential for:

   • Chlorophyll synthesis

   • Photosynthesis

   • Energy transfer and metabolism

3. EDTA keeps iron in a soluble, plant-available form, preventing it from becoming insoluble in soil

• Application Methods:

1. Soil application (best in slightly acidic to neutral soils)

2. Foliar sprays

3. Fertigation

4. Hydroponics

Key Benefits:

• Contains about 12–13% elemental iron.

• Effective in soils with pH up to ~6.5 — above this, Fe-EDTA can break down and lose effectiveness.

• Prevents iron lock-up in soil due to pH or interaction with other minerals.
