EDDHA FE 6% with 4.8 O-O is a premium-grade chelated iron fertilizer representing the highest biological activity among EDDHA iron products. It is characterized by its exceptional stability and bioavailability across a wide pH range.
High-performance chelated iron with 6.0% total iron content and 4.8 Ortho-Ortho isomer level, giving it superior performance compared to conventional iron fertilizers.
Studies have found that iron-deficiency-sensitive crops such as soybeans can increase yield by up to 30% and tissue iron content by up to 50% after application. High O-O content products achieve significant effects with lower dosages, improving economic benefits and reducing environmental risk.
