Plants remove significant amounts of Sulphur and Magnesium as they grow and develop. Sulphur and Magnesium are not replaced by many of today’s high analysis fertilizers.
Sul-Po-Mag has an analysis of 22% Sulphur (S), 22% Potash (K2O), and 11% Magnesium (Mg). Potash stimulates and promotes root growth and development and increases plant vigor, stem strength and resistance to many diseases. Potassium is a key in the prevention of plant diseases. Magnesium is necessary to the formation of chlorophyll and is essential for plant utilization of Nitrogen, Phosphorous and Sulphur.
