Overview
Zinc sulfate monohydrate is a highly soluble, white crystalline granular form of zinc sulfate containing one molecule of water of crystallization. It is an important source of zinc in various agricultural, industrial, and chemical applications. Its high water solubility makes it suitable for liquid formulations and rapid uptake.

Applications

1. Agriculture:

   • Used as a micronutrient fertilizer to correct zinc deficiency in crops (e.g., cereals, vegetables, fruit trees).

   • Added to animal feed as a zinc supplement for livestock and poultry to support growth, immune function, and reproductive health.

2. Industrial:

   • Used in the production of lithopone (a white pigment) – a mixture of zinc sulfide and barium sulfate.

   • Acts as a mordant in dyeing and textile processing.

   • Functions as an astringent and wood preservative.

   • Used in the manufacture of zinc salts and other chemical intermediates.

   • Employed in electroplating and water treatment processes.

Key Benefits

• High water solubility – ensures rapid dissolution and availability.

• Stable and easy to handle.

• Cost-effective source of zinc for both agricultural and industrial uses.

Recommended Use
Agricultural applications: Zinc sulfate monohydrate is typically applied at 0.5–5 kg/ha (soil application) or as a foliar spray at 0.5–2% concentration. For animal feed, typical inclusion rates are 50–150 mg/kg feed (as elemental zinc), depending on species and requirements.

Handling and Storage

• Store in a cool, dry, well-ventilated area, away from moisture and incompatible materials (strong oxidizers).

• Keep containers tightly sealed to prevent caking and contamination.

• Use appropriate personal protective equipment (gloves, safety goggles, dust mask) when handling.

• Avoid inhalation of dust and contact with skin and eyes.

Packaging
Available in 25 kg or 50 kg plastic woven bags with inner liner, or 1000 kg bulk bags. Custom packaging available upon request.

Quality Assurance
Each batch is tested for zinc content, heavy metals, moisture, and solubility to ensure compliance with agricultural and industrial quality standards.
