Sulfate of Potash (SOP) – Potassium Sulfate Fertilizer | 50–52% K₂O + 17–18% S | Powder / Granular | Premium Chloride-Free Grade

DESCRIPTION:

Sulfate of Potash (SOP), also known as Potassium Sulfate (K₂SO₄), is a premium potassium fertilizer designed for high-value crops and chloride-sensitive soils. With 50–52% K₂O and 17–18% sulfur, SOP provides a balanced nutrient profile that strengthens crop quality, boosts sugar content, improves disease resistance, and supports protein formation.

Unlike Muriate of Potash (MOP), SOP contains no chloride, making it the preferred potassium source for crops such as potatoes, fruits, vegetables, coffee, tea, tobacco, nuts, and ornamentals. Its low salt index ensures safer application in saline soils and high-irrigation environments.

Available in fine powder and uniform granules, SOP integrates seamlessly into NPK production, fertigation, bulk blending systems, and specialty fertilizer programs.

Engineered for importers, agro-distributors, blending plants, commercial farms, greenhouse producers, and government agricultural programs.
