#Potassium is the third major nutrient in chemical fertilizers. It helps strengthen the plant's ability to resist diseases and plays an important role in increasing crop productivity and overall quality. Potassium also protects the plant when the weather is cold or dry, strengthening its root system.

# Potassium sulphate (K2SO4) or sulphate of potash (SOP) is the most popular low chloride potassium fertilizer in the world. The combination of potassium (52% K2O) and sulfur (18% S) provides highly concentrated nutrients that are readily available to plants.

#Potassium sulfate provides both potassium and sulfur in soluble forms.

# Potassium sulphate has a low chloride content and therefore has a much lower salt index than MOP (KCL). Where soil is saline and where irrigation water may contain high levels of chloride, SOP is the preferred form of potassium to use.

# When seeds or seedlings are placed in direct contact with fertilizers, SOPs are less likely to cause plant root burn.

# Potassium sulfate stimulates the growth of strong stems and gives the plant some resistance to diseases by enhancing the thickness of the outer cells. Adequate potassium can reduce moisture loss from developing plants, giving some resistance to drought. Potassium improves the color, flavor and storage quality of fruits and vegetables.
