EDTA ferric ammonium salt is a chelated iron compound primarily used as a micronutrient in agriculture and horticulture. It supplies bioavailable iron to plants, preventing iron deficiency symptoms such as chlorosis and supporting vigorous growth. The EDTA chelation enhances iron solubility and stability across a wide pH range in soils, making it effective in various growing conditions. It is also incorporated into fertilizers, foliar sprays, and hydroponic solutions. In animal nutrition, it serves as an iron supplement in feeds to address deficiencies. Additionally, in laboratory applications, it acts as a reagent for iron supplementation in cell culture media or as a reference standard in analytical procedures involving iron. Its controlled iron release properties find use in some industrial formulations requiring stable iron sources.
