Chelated micronutrient
EDTA-Zn — Zinc EDTA Chelate
EDTA-Zn is a stable, fully water-soluble zinc chelate in which the zinc is held in chelated form, protecting it against fixation in the tank and in soil. It is used as a raw-material additive in foliar, fertigation and compound micronutrient fertilizers.
