EDDHA (ethylenediamine-N,N′-bis(2-hydroxyphenylacetic acid)) (Cat No.: R016123) is a chelating agent commonly used in agriculture to correct micronutrient deficiencies, particularly iron (Fe). It forms stable complexes with metal ions, enhancing their solubility and bioavailability in alkaline and calcareous soils. EDDHA-Fe is especially effective due to its resistance to photodegradation and strong iron-binding capacity. It promotes healthy plant growth by preventing chlorosis and improving nutrient uptake. EDDHA is also used in hydroponics and soil science for precise nutrient management in crop production systems.
