Brian von Herzen is director of the Climate Foundation, working on developing seaweed permaculture. David Demarey is a farmer and soil chemist. Thomas Vanacore owns a quarry and is an expert on farming with rock dust. They discuss the potential use of rock dust, biochar, and seaweed extract in a mixture to improve the fertility of soil while retaining the nutrients in it and preventing run-off to pollute waterways and oceans. Fortunately, such a mixture can attract and sequester large amounts of carbon from the atmosphere, becoming a major mechanism for climate restoration, while even improving the immune systems of animals and people who consume the food from such soil.
