The major source of potassium is potash which is processed from potassium bearing ores like sylvanite.

Potassium from potash is referred to as the regulator in crop production influencing over 60 enzyme systems which control crop quality. Potassium fertilizers enable plants grow strong stalks and resist stress such as weeds, diseases and changes in the temperature.

Potassium helps to promote root growth and the uptake of nitrogen which promote higher yields, improve the quality and taste of fruits and vegetables, enhance water retention, and increases disease resistance. Adequate potassium nutrition is essential for healthy growth, for the plant’s strength and for excellent yield quality.
