Product type
Zinc sulfate fertilizer is a chemical compound that provides essential zinc nutrients to plants, promoting healthy growth and development. It is typically produced through the reaction of zinc oxide or zinc metal with sulfuric acid, resulting in a water-soluble form that can be easily absorbed by crops. This fertilizer is often used to correct zinc deficiencies in soils, which can hinder plant growth and reduce crop yields.

| Solubility | Highly soluble in water |
| Appearance | White crystalline solid or powder |
| Zinc content | Typically 20-36% by weight |
| Granule size | Varies from fine powder to granules of 1-4 mm |
When selecting zinc sulfate fertilizer, buyers should consider the desired zinc content and the form required (granular or powder). It is important to specify the intended application method, as this may influence the granule size or solubility needed. Additionally, buyers should inquire about the purity and any relevant certifications to ensure the product meets agricultural standards. Quantities should be based on the area of application and soil testing results.
