He joins me to share his passion for terra preta soil and biochar and how he turned that love into an entrepreneurial business bringing a regenerative product to market. Along the way, he shares the difference between simply burning something and calling biochar versus creating a carbon-rich, mineralized biochar, the importance of nutrient ratios for sustainable growing, and much more.\n\n\n\n\xa0\n\nMore Information on Terra Preta and Biochar\nTerra Preta (Wikipedia)\nBiochar (Wikipedia)\nThe Biochar Solution by Albert Bates\nBurn by Albert Bates and Kathleen Draper\n\nRelated Interviews\nDr. Elaine Ingham - The Soil Food Web\nEric Toensmeier - Drawing Down Carbon: Agroforestry and Climate Change\nPermabyte: Biochar, Gasification, and Woodlot Management\nMary Johnson - An Introduction to Nutrient Dense Farming\nConnor Stedman - Carbon Farming - Soil\n\n\n\n\xa0\nLearn More
