Agricultural Zinc Sulfate Heptahydrate for Soil Amendment

- Chemical Name: Zinc Sulfate Heptahydrate (also known as Glauber's Salt or Zinc Alum)

- Molecular Formula: ZnSO₄·7H₂O

- Molecular Weight: 287.56

- CAS Number: 7446-20-0

- H.S Code: 2833293000

- Zinc sulfate heptahydrate (white vitriol) is an inorganic zinc salt. It typically appears as white crystalline granules, has no distinctive odor, and has an astringent, bitter taste when ingested. Its most notable characteristic is its high water solubility; it dissolves rapidly in water but is sparingly soluble in alcohol.

- When left in dry air for an extended period, it gradually loses its crystalline water and turns into a loose powder; when heated, it gradually dehydrates and completely decomposes at very high temperatures. It is not combustible, but its aqueous solution is slightly acidic and should not be mixed indiscriminately with strong alkalis; it must be stored in a sealed container to protect against moisture and avoid prolonged exposure to high temperatures.

- It is widely used in electroplating, dyeing and printing as a mordant, for zinc supplementation in animal feed and fertilizers, in water treatment, and as a topical astringent in medicine.

- Product Categories: Zinc sulfate heptahydrate is available in several grades, including industrial-grade, agricultural-grade, rubber additive-grade, electronic-grade, and pharmaceutical-grade. Each grade is available in different particle sizes: 2–4 mm, 1–3 mm, and <1 mm.

- Product Keywords: zinc sulphate heptahydrate agriculture use; zinc sulphate heptahydrate use in agriculture.

(I) Core Ingredients

Primary Ingredient: Zinc sulfate heptahydrate (ZnSO₄·7H₂O), serving as a highly efficient zinc source (Zn²⁺) for industrial production and the core functional component. No auxiliary agents or fillers are added, ensuring pure composition.

(II) Product Specifications

1. Replenishes available zinc in the soil to address issues such as dwarfism, stunted growth, and flower abortion caused by zinc deficiency in crops.
2. Supplies sulfur to improve soil nutrient structure and enhance crop stress tolerance.
3. Its mildly acidic nature helps slightly adjust the pH of alkaline soils and increases the availability of trace and microelements.
4. Promotes photosynthesis, chlorophyll synthesis, and root growth in crops, thereby improving yield and quality.
5. Improves soil microbial activity, facilitates organic matter decomposition, and optimizes soil fertility.

• Field Crops: Corn, rice, wheat, cotton, rapeseed, peanuts (highly effective against "white tip disease" in corn and "stunted seedlings" in rice).
• Vegetables: Tomatoes, cucumbers, Chinese cabbage, cabbage, celery.
• Fruit Trees: Apple, pear, peach, citrus, grape (controls chlorosis).

• Standard Packaging: Double-layer packaging bags with inner plastic and outer woven layers, providing moisture resistance, leak prevention, and abrasion resistance. Standard specification is 25kg/bag; bulk bag packaging can be customized upon request.
• Packaging Labeling: Packaging can be customized according to customer requirements.

(II) Transportation Requirements

- Transportation Methods: Road or sea freight. Classified as general cargo requiring no special transport permits.

- Transportation Precautions:

- Vehicles must be clean, dry, and odor-free. Avoid co-loading with alkaline substances or oxidizing agents.

- Handle with care during loading/unloading to prevent bag damage.

- Implement rainproof, moisture-proof, and sun-proof measures during transit to prevent product dampness or weathering.

(III) Storage Conditions

- Store in a dry, well-ventilated, cool warehouse away from water sources, heat sources, and direct sunlight. Warehouse relative humidity must not exceed 60%.

- Stack products at least 10 cm above the floor and away from walls to prevent moisture absorption. Shelf life is 12 months (unopened and stored under specified conditions). Use promptly after opening and reseal tightly.

- Periodically inspect packaging integrity during storage. If bags are damaged or product has caked, handle promptly. This does not affect product efficacy.

(IV) Safety Precautions

- This product is acidic. Avoid direct contact with skin or eyes. Wear gloves and safety goggles during handling. If contact occurs, immediately rinse thoroughly with copious amounts of water.

- Do not ingest. Store in areas clearly marked with"NOT FOR CONSUMPTION" warnings. Keep separate from food and animal feed.
