SOP (Sulphate of Potash), also known as Potassium Sulphate (K₂SO₄), is a premium potassium fertilizer that provides both potassium and sulfur without containing chloride. It is especially suitable for chloride-sensitive crops and high-value agriculture such as fruits, vegetables, tobacco, and horticultural crops.

Potassium in SOP supports strong plant growth, improves water regulation, enhances disease resistance, and increases crop yield and quality. The sulfur content plays a key role in protein synthesis, enzyme function, and overall plant metabolism.

SOP is ideal for improving fruit size, taste, color, and shelf life, making it a preferred choice for export-quality produce. It can be applied directly to the soil or used in fertigation systems for efficient nutrient delivery.
