General description
Zinc sulphate CAS No.: 7446-19-7
Zinc sulphate granular: Used as a zinc fertilizers.

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 is one of the essential elements for plant and animal life. In plants, it serves as a growth hormone and influences protein synthesis. 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.

It should be stored in a dry and ventilated warehouse and avoid sundry odors pollution. Sunlight and rain should be prevented during transportation
