David Demarey is a soil chemist and farmer; Tom Vanacore owns a quarry and makes rock dust; John Sewuster is an expert on seaweed farming; Ted Wysocki is a farmer, and Ryan Brophy is an agronomist. What they have in common is a conviction that mixing rock dust, biochar, and seaweed produces a soil amendment that can not only improve the quality of soil and the food that it produces, but also capture significant amounts of carbon dioxide from the air and sequester it, while reducing the emission of nitrous oxide and other pollutants to the environment. This would save far more money than the cost of switching to this form of agriculture. For the video, audio podcast, and comments column, https://tosavetheworld.ca/episode-497-rocks-biochar-seaweed
