SOP
SOP is a granular source of potassium in the form of potassium sulphate for use in crops with a high demand for potassium, and pastures grown for forage and hay. SOP is especially suited for use in situations where MOP use is not desirable due to its high chloride content, like a numerous horticultural applications. SOP contains no chloride and hence has a much lower salt index than MOP. Where soils are saline or sodic and where irrigation water may have high chloride levels SOP is the preferred form of potassium to use. Available in granular, fines and water soluble forms.
