硫酸钾 (K₂SO₄)

硫酸钾 (K₂SO₄), 又称 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 和 18% sulfur, it enhances crop yield and quality while improving resistance to drought and disease.

在 卡文资源, our Potassium Sulphate is produced through both Mannheim furnace process 和 reactive crystallization from potassium chloride and sulfuric acid. This ensures low-chloride, high-solubility SOP tailored for professional agriculture. Potassium sulphate k₂so₄ 肥料 

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

⚙️ 生产方式

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

📦 包装选项

• 25kg and 50kg woven PP bags

• 1000kg jumbo bags for bulk orders

• Palletized or containerized shipping available

🏭 按行业划分的使用案例

❓ 常见问题（FAQ）

1. Is Potassium Sulphate safe for all crops?

请回答：
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?

请回答：
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?

请回答：
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?

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