Sulphate of Potash (SOP) is a premium potassium fertiliser that provides essential nutrients for optimal plant growth. It contains 41.5% potassium and 17% sulphur, promoting strong stems, improved disease resistance, and enhanced drought tolerance. SOP is ideal for chloride-sensitive crops and saline soils, ensuring better quality and yield of fruits and vegetables. Its low salt index and absence of chloride make it a superior choice for maintaining soil health and crop productivity.

SOP is available in granular form, with a nominal particle size of 2-4 mm, ensuring easy application and uniform distribution. It is packaged in bulk bags for convenient storage and handling. The product's slightly hygroscopic nature requires proper storage to maintain quality. Suitable for various crops, SOP's user-friendly packaging and application make it practical for diverse agricultural scenarios, enhancing efficiency in fertilisation practices.
