Using biochar to improve soil resilience and sequester carbon

For the opening presentation in this fall's Speaker Series, soil scientist Debbie Page-Dumroese will discuss the use of biochar to sequester carbon and improve soil resilience. Biochar is a porous, high-carbon material derived from exposing biomass to temperatures above 500°C in a low-oxygen environment. The resultant “char” is typically used as a soil amendment to increase water-holding capacity and nutrient retention. Page-Dumroese has been a Research Soil Scientist with the USDA Forest Service Rocky Mountain Research Station for over three decades. Her work focuses on long-term soil productivity after harvest operation, sustainable harvesting, wood decomposition, and biochar. For the last ten years, she has been investigating the potential to reduce slash pile burns and limit wildfire risks by using onsite biochar conversion technologies.
