Sodium Hydrogen Ferric DTPA is a stable iron chelate primarily used as a micronutrient in agriculture to supply bioavailable iron to plants. It helps prevent and treat iron deficiency chlorosis by delivering iron in a form that remains soluble across a wide pH range (typically 4-7). Commonly incorporated into fertilizers, soil amendments, hydroponic nutrient solutions, and foliar sprays, it enhances plant growth and chlorophyll production. Additionally, it finds limited use in industrial applications requiring controlled iron supplementation, such as in certain nutrient media or water conditioning where iron stability is needed.
