Ultrasol® micro Rexene® FeD12 is a stable, water-soluble iron-DTPA chelate developed for high performance in hydroponic systems, but also suitable for soil and foliar applications. Fe-DTPA products have a higher pH stability than EDTA products, making them a preferred source in hydroponic systems. Typical iron (Fe) content is 11.6%, fully chelated by DTPA, with a pH stability of 1.5 to 7.5.
