How Canadian Wollastonite Works
Carbon-neutral Calcium: When calcium carbonate (lime) reacts in the soil, it releases carbon dioxide. Wollastonite breaks down into calcium and silicon, and is, therefore, carbon neutral. Like lime, the calcium helps balance soil pH and supplies calcium for high-quality plant growth. Wollastonite can capture up to %62 CO2 by weight, that is 620 ...
