What is Potassium Sulphate (SOP)?

Potassium Sulphate (K₂SO₄), also known as Sulphate of Potash, is a water-soluble, white crystalline salt that serves as an acidic potassium fertilizer. SOP is unique for its ability to release nutrients trapped in the soil, which enhances the absorption of other elements. By providing essential potassium and sulfur, SOP helps boost plant growth, improve yield, and support high-quality fruit production.

This potassium-rich fertilizer is especially beneficial during the fruit formation stage, as it increases fruit size, enhances coloring, and strengthens stems without promoting excessive vegetative growth. SOP is suitable for various crops, including vegetables, fruit trees, and ornamental plants.

Key Benefits of Potassium Sulphate (SOP)

• Enhances Nutrient Absorption: Releases trapped nutrients in the soil, improving the availability of essential elements.
• Boosts Fruit Quality: Increases fruit size, enhances color, and strengthens stems for robust growth.
• Essential Potassium and Sulfur Supply: Provides key nutrients needed for healthy plant development, improving yield and crop resilience.
• Versatile Crop Compatibility: Effective for vegetables, fruit trees, ornamental plants, and field crops.
