Potassium nitrate (NOP) is a highly soluble fertilizer widely used in high-value crops such as fruits, vegetables, and flowers, providing both potassium and nitrate-nitrogen for rapid uptake and strong growth. It is also valued in industrial applications, including glass manufacturing, specialty chemicals, and food preservation.

Potassium sulfate (SOP) is an essential fertilizer for chloride-sensitive crops like tobacco, potatoes, and many fruits, delivering potassium and sulfur without adding chloride. Beyond agriculture, SOP is also used in specialty chemicals and various industrial processes where purity and consistency are critical.
