Ultrasol® micro Rexene® FeXQ58 is a stable, water-soluble, dust-free blend of iron chelated Fe HBED and Fe EDDHA. Chelation with HBED and EDDHA protects iron (Fe) from binding in the soil, keeping it available for plant uptake. This is especially important in alkaline and calcareous conditions where iron deficiency needs to be corrected or prevented to optimize plant yield and quality. High quality chelates make Ultrasol® micro Rexene® FeXQ58 a good choice for extending iron availability for a wide range of vegetable and fruit crops. The typical iron (Fe) content is 6.0%, of which 4.0% is the ortho-ortho isomer of Fe-HBED and 1.8% is the ortho-ortho isomer of Fe-EDDHA. It is stable within a pH range of 3.5 to 12 and has a water solubility of 75 g/L for practical use.
