Magnesium Sulphate – Agricultural & Industrial Grade

Magnesium Sulphate (MgSO₄) is a white, odorless, crystalline solid available primarily in heptahydrate form (MgSO₄·7H₂O). It is valued for its magnesium-rich content, solubility in water, and non-toxic properties, making it widely applicable in both biological and industrial systems.

In agriculture, Magnesium Sulphate serves as a soil amendment that delivers essential magnesium and sulfur nutrients to crops, improving photosynthesis and yield. In the pharmaceutical sector, it is used as a saline laxative and in intravenous therapies. Industrial applications include textile dyeing, paper processing, and fireproofing.

Cavin Resource delivers bulk Magnesium Sulphate with consistent quality, high solubility, and customizable particle sizes for varied use cases in fertilizer blends, feed formulations, and more.

Chemical Neutralization Process

1. Sulfuric acid (H₂SO₄) reacts with magnesium carbonate or oxide

2. The solution is then crystallized and dried to obtain heptahydrate or anhydrous forms

3. Purification steps ensure compliance with agricultural, food, or pharma-grade standards

1. What is the difference between heptahydrate and anhydrous Magnesium Sulphate?

Heptahydrate contains 7 water molecules (MgSO₄·7H₂O) and is commonly used in agriculture. Anhydrous has no water content and is preferred for some industrial and lab uses.

---

2. Is Magnesium Sulphate safe for edible crops?

Yes. It’s a plant-safe, soil-safe fertilizer approved for use in organic and conventional farming.

---

3. Can it be used in livestock feed?

Yes, in controlled quantities, it boosts magnesium intake in animals.

---

4. Do you supply pharma or food-grade Magnesium Sulphate?

Yes. We offer multiple grades including technical, food, feed, and pharmaceutical-grade upon request.
