Fire-Derived Charcoal Causes Loss of Forest Humus


David A. Wardle,* Marie-Charlotte Nilsson, Olle Zackrisson 

Fire is a global driver of carbon storage and converts a substantial
proportion of plant biomass to black carbon (for example, charcoal), which
remains in the soil for thousands of years. Black carbon is therefore often
proposed as an important long-term sink of soil carbon. We ran a 10-year
experiment in each of three boreal forest stands to show that fire-derived
charcoal promotes loss of forest humus and that this is associated with
enhancement of microbial activity by charcoal. This result shows that
charcoal-induced losses of belowground carbon in forests can partially
offset the benefits of charcoal as a long-term carbon sink.

Agricultural Sciences, SE901-83 Umeå, Sweden.

Google found this shallow story for me. I hope this is not a redundant
posting.
