The guest for this episode is Mark Ervin of GreenGro Biologicals. 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.
