Straight and secondary nutrient fertilizers

Both supply potassium. Sulphate of potash (SOP, potassium sulphate) is chloride-free and adds sulphur, so it is preferred for chloride-sensitive crops such as fruits, vegetables, tobacco and potato. Muriate of potash (MOP) contains chloride.

Ammonium sulphate has an acidifying effect in the soil, which suits alkaline soils, and it supplies sulphur alongside nitrogen, which benefits oilseeds, pulses, onion and other sulphur-demanding crops.

Potassium schoenite supplies potassium, magnesium and sulphur together in a chloride-free form, so it is useful where crops need both potassium and magnesium, such as on sandy or magnesium-deficient soils.
