Citrate Chelated Iron
High-Purity Citrate Chelated Iron for Fertilizer Manufacturing and Specialty Crop Nutrition
Citrate Chelated Iron Ingredient for Modern Fertilizer Formulations
Citrate Chelated Iron is a highly water-soluble micronutrient fertilizer produced by chelating iron with citric acid. Containing 17% iron, it provides an efficient source of plant-available iron for correcting iron deficiency and supporting healthy crop development.
Citric acid acts as a natural organic chelating agent that improves iron solubility and facilitates nutrient absorption. Compared with inorganic iron salts, Citrate Chelated Iron offers better nutrient availability, reduced precipitation, and improved compatibility in fertilizer formulations.
It is widely used in foliar fertilizers, liquid fertilizers, fertigation programs, hydroponics, and specialty fertilizer manufacturing.
