EDTA FeK 13% is a concentrated chelated iron micronutrient fertilizer used in crop nutrition programs. It is commonly employed to correct iron deficiencies in field and horticultural crops through foliar spray or soil fertigation application. Additionally, it serves as a stable, highly soluble iron source that improves plant uptake compared to inorganic iron salts. FeK EDTA is also utilized in nutrient management programs for high-value crops sensitive to iron chlorosis. Furthermore, it finds applications in blended micronutrient fertilizer formulations requiring a reliable iron chelate.
