Potash
Potash refers to a number of forms of potassium (K) and is a natural resource found in the earth. Potassium is found in every cell of living plants and animals. Potash is an indispensable supplement to the natural nutrient content of soils.

Primarily used as a fertilizer as it strengthens plant stalks and roots, improves water retention, helps fight plant diseases, and thus improves crop yields
Canada is the largest producer and exporter of Potash in the world which contributes over $18 billion to Canada’s economy. By 2050, on decreasing farmland, yields will have to increase by 70% in order to feed the world’s growing population.
