Zinc sulfate is chiefly used in fertilizer applications and animal feed supplements. It is especially applied on crops such as pecan, deciduous fruits, peanuts, cotton, corn, and citrus, and added to feeds for swine and poultry.

Zinc deficiency causes stunting of the plant, yellowing of the leaves and decreased yields of seed, grain, vegetables or fruit. Soil application of zinc sulfate is the most common and most successful long-term strategy for eliminating zinc deficiencies.
