Cosmetics: Often found in skincare products for its soothing, anti-inflammatory, and antimicrobial properties.
Plant Growth:
Zinc is essential for various plant metabolic processes, including enzyme function, protein synthesis, and chlorophyll production.
Promotes root development, flowering, and overall plant health.
Improved Crop Yields:
Correcting zinc deficiencies with zinc sulfate heptahydrate improves crop yields and quality, especially in crops like cereals, legumes, and vegetables.
Soil Health:
Helps in adjusting soil pH, especially in alkaline soils, making essential nutrients more available to plants.
For Crops:
Dosage: Typically 5–10 kg per hectare, depending on the zinc levels in the soil.
Application: Can be applied directly to soil or used as a foliar spray for faster absorption.
For Animal Feed:
Dosage: Added to animal feed at concentrations of 40–100 mg of zinc per kg of feed, depending on the animal's needs.
Application: Mixed into the feed or provided as a supplement.
Storage:
Store in a cool, dry place, away from moisture.
Keep containers tightly sealed to prevent contamination.
Handling Precautions:
Use appropriate personal protective equipment (PPE), such as gloves and masks, to avoid direct contact or inhalation of dust.
Ensure handling in well-ventilated areas.
Toxicity:
Zinc sulfate heptahydrate is generally safe when used as directed, but excessive exposure can lead to toxicity.
Avoid ingestion or inhalation of large quantities.
Environmental Impact:
Care should be taken to avoid contamination of water sources during application or disposal.
Disposal:
Dispose of excess material according to local environmental regulations to minimize environmental impact.
Zinc sulfate heptahydrate is an important compound in agriculture, animal nutrition, and various industrial applications. By providing a soluble source of zinc, it enhances plant growth, improves crop yields, supports animal health, and contributes to industrial processes like electroplating and water treatment.
