What mineral is commonly used as a fertilizer in Canada?

Potash is the mineral commonly used as a fertilizer in Canada due to its high potassium content, which is essential for plant growth. Canada is one of the largest producers of potash in the world, particularly in the provinces of Saskatchewan and New Brunswick. Potassium is a vital nutrient that helps plants with processes such as water regulation, photosynthesis, and overall growth and development. The significance of potash in agriculture cannot be overstated, as it enhances crop yields and improves the quality of produce, making it a crucial component of modern farming practices in Canada.
