Zinc chelate is easily translocated within the plants, because unlike Zinc Sulphate it is partly systemic. Zinc Sulphate reduces phosphorous uptake and the phosphorous content in the shoots of plants, while Zn-EDTA increases it. Non EDTA Zinc from other sources makes Zinc available very slowly, because a large quantity of such Zinc will be fixed in the soil. Zinc EDTA is versatile since it can be used for all crops and all kinds of soil.
