Frequently asked questions
Iron ammonium EDTA solution is a liquid formulation where iron is chelated with EDTA in an ammonium salt solution. Compared to solid iron sodium EDTA, the liquid form is easier to dilute and use, especially suitable for liquid fertilizer formulations and direct addition to irrigation systems, eliminating the dissolution step.
Store in a dry place, avoid contact with alkaline substances. Keep container tightly closed, handle with care.
