EDTA Fe
EDTA-Chelated Iron
AI-generated imageIron bound to EDTA, the most common and cost-effective iron chelate, stable and plant-available up to roughly pH 6.5 — the classic correction for iron chlorosis, which shows as interveinal yellowing in the youngest leaves since iron is nearly immobile within the plant. EDTA-Fe is the standard first choice for moderate-pH soils; above pH 6.5-7 its stability drops off sharply, which is where DTPA- or EDDHA-chelated iron becomes necessary instead.
- Most widely used and cost-effective iron chelate
- Corrects interveinal chlorosis in youngest leaves, the classic iron-deficiency symptom
- Effective up to roughly pH 6.5-7; higher-pH soils require DTPA or EDDHA chelates instead
Available in 1 kg, 5 kg and 25 kg moisture-proof bags. Storage: Store in a cool, dry place away from sunlight and humidity.

Chelation surrounds metal nutrients (Fe, Zn, Mn, Cu, Ca, Mg) with protective organic molecules, keeping them fully soluble and plant-available across a wide range of soil pH levels to ensure effective nutrient delivery.
EDTA Zn
Zinc bound to EDTA, the standard synthetic chelating agent, keeping zinc plant-available in solution up to roughly pH 6.5-7.5 rather than precipitating out as it would in an unchelated salt. Zinc deficiency shows first in new growth as shortened internodes and interveinal chlorosis ("little leaf"), a common issue in high-pH or high-phosphorus soils that lock up free zinc. Chelation gives more reliable foliar and fertigation uptake than sulfate forms under those conditions.
EDTA Mn
Manganese bound to EDTA, keeping the nutrient in plant-available form for foliar or fertigation delivery up to roughly pH 6.5-7.5. Manganese deficiency appears as interveinal chlorosis on middle-to-young leaves, most common on high-pH or poorly aerated soils where manganese becomes chemically unavailable regardless of total soil content. Chelation avoids the fixation that limits sulfate-form manganese in those same conditions.
