Used in agriculture as a micronutrient fertilizer to correct iron deficiency in plants, especially in alkaline soils where iron becomes less available. Promotes chlorophyll production and helps prevent or treat chlorosis, leading to healthier green foliage and improved crop yields. Also used in hydroponic systems to supply essential iron in chelated form. In industrial settings, employed in water treatment processes and as a reagent in chemical synthesis. Commonly applied in laboratories for calibration and analytical testing involving iron content.
