Saskatchewan, Canada is the world’s largest producer and exporter of potash

Potash refers to a group of minerals and chemicals that contain potassium (chemical symbol K), a basic nutrient for plants and prime ingredient in fertilizer. It is observed that most of the potash produced is as potassium chloride (KCl), even though it is often measured and described in terms of potassium oxide (K2O) equivalence for consistency as a result of deposits that could have different percentages of potassium.
