Muriate of Potash

MOP is the most concentrated form of granular potassium and typically the most cost effective. The granule size of MOP allows for accurate spreading. MOP is commonly blended with SSP to supply major nutrients for pasture based systems. Potassium stimulates the growth of strong stems and gives the plant some disease resistance by promoting thickness of the outer cell walls. Adequate potassium can reduce moisture loss from growing plants, thereby giving some drought resistance.
