Burn Piles: Biochar and Conventional

Here are some pictures of burn piles on the Rogue-Siskiyou National Forest, burned in December 2015. Some were done the conventional way, with the objective of incinerating as much biomass as possible. Others were top-lit and then extinguished with water in order to preserve the charcoal. You can see that the conventional method burned the organic soil layer down to mineral dirt and rocks. Nothing grows there now, and where the piles were on slopes, erosion has started.

In contrast, biochar burn piles have new sprouts of ferns, wildflowers and other plants.
