Prairie Fires: Can a Controlled Burn Act as a Natural Process and Make Biochar as Soil Carbon?

Wildfires were and are still common in the North American Prairie lands, and the flowers and grasses that make up this amazing ecosystem evolved as a result. For those that live in prairie regions, controlled prairie fires are a sign of spring.  Non-native plants are burned away during each burn, giving prairie species more nutrients and space to develop. Because prairie plants have deep roots and develop from a place underground, they can withstand fires. In prairie restoration, a prescribed burn is essential. As this is a burn process, there is resulting carbon.
