Potassium Ranges

Potassium (K) is one of the major nutrients required by the plant in large amounts, (about 1.5 to 2.0% of plant weight). It has a variety of roles in the plant including osmoregulation and photosynthesis.

Our Potassium range consists of Sulphate of Potash (SOP) and Muriate of Potash (MOP), which can be custom blended with other products or used as stand-alone fertilizers.

MOP contains the highest concentration of K of any of our products, and as such is normally the most cost-effective source of K for farmers.

SOP still contains a high concentration of K, but also contains sulphur which is essential for protein production in plants. Another advantage is that SOP has a reduced salt index compared to MOP.
