Potassium Sulphate (K₂SO₄)

Potassium Sulphate (K₂SO₄), also known as Sulfate of Potash (SOP), is a premium, chloride-free fertilizer ideal for high-value crops such as fruits, vegetables, tobacco, and coffee. With a potassium content of 50% K₂O a 18% sulfur, it enhances crop yield and quality while improving resistance to drought and disease.

At Adnodd Cavin, our Potassium Sulphate is produced through both Mannheim furnace process a reactive crystallization from potassium chloride and sulfuric acid. This ensures low-chloride, high-solubility SOP tailored for professional agriculture. Potassium sulphate k₂so₄ fertilizer 

Available in granular or powder form, our SOP is delivered in export-grade packaging with consistent global supply capability. bulk potash fertilizer for sale

⚙️ Production Method

1. Mannheim Process

• Potassium chloride reacts with sulfuric acid in a furnace

• The byproduct hydrochloric acid is removed

• The remaining product is cooled and granulated

2. Crystallization Process

• Reacts potassium chloride with sulfuric acid in solution

• Crystals of potassium sulphate form and are harvested

• Final product is dried and screened

📦 Packaging Options

• 25kg and 50kg woven PP bags

• 1000kg jumbo bags for bulk orders

• Palletized or containerized shipping available

🏭 Use Cases by Industry

🌾 Agriculture

• 🚢 Global Supply Ready: Consistent stock and export logistics

❓ Frequently Asked Questions (FAQs)

1. Is Potassium Sulphate safe for all crops?

Answer:
Yes, especially for chloride-sensitive crops. It provides essential potassium and sulfur without the harmful effects of chloride.

2. What’s the difference between SOP and MOP fertilizers?

Answer:
SOP (Potassium Sulphate) contains no chloride, making it ideal for sensitive crops. MOP (Potassium Chloride) is cheaper but contains high chloride levels, which may harm certain plants.

3. Can I mix SOP with other fertilizers or agrochemicals?

Answer:
Yes, SOP is compatible with most fertilizers and can be used in fertigation, foliar sprays, and direct soil application.

4. Do you offer SGS or third-party analysis with the product?

Answer:
Yes, we provide SGS certification, COA, and MSDS with every shipment upon request.
