Used as a chelating agent in agriculture to deliver iron to plants in a stable and bioavailable form. It prevents iron deficiency in crops, especially in high-pH soils where iron tends to become insoluble and inaccessible. Commonly applied in horticulture, greenhouse farming, and hydroponic systems to correct chlorosis and support healthy plant growth. Also utilized in some medical and pharmaceutical formulations as an iron source due to its stability and low toxicity.
