DTPA Iron (DTPA-Fe)
High-Purity Chelated Iron for Fertilizer Manufacturing and Specialty Crop Nutrition
Chelated Iron Ingredient for Modern Fertilizer Formulations
DTPA Iron (Diethylenetriaminepentaacetic Acid Iron) is a highly water-soluble synthetic chelated iron fertilizer designed for efficient iron nutrition in moderately alkaline growing conditions. Compared with EDTA iron, DTPA provides greater stability over a wider pH range, making it an excellent choice for fertigation, hydroponics, greenhouse production, and liquid fertilizer formulations.
Its excellent compatibility, high solubility, and reliable chelation performance make DTPA-Fe one of the preferred iron sources for professional crop nutrition programs.
Key Benefits
Higher pH stability than EDTA iron
Excellent water solubility
Reliable iron availability in moderately alkaline conditions
Outstanding compatibility with liquid fertilizers
