FAQ
EDTA FeNH₄ Solution is a liquid formulation where iron exists in an EDTA chelated form in an ammonium salt solution. Compared to solid EDTA FeNa, the liquid form is easier to dilute and use, especially suitable for liquid fertilizer formulas and direct addition to irrigation systems without the need for dissolving steps.
Store in a dry place, away from alkaline substances. Keep container tightly closed, handle with care.
