Biochar cuts soil GHG by one-third - study finds

Researchers are now saying that biochar — charcoal used to treat soil — has the potential to not only increase soil fertility, but to sequester carbon and cut greenhouse gas emissions (GHG). 

A March 2013 study by Sean Case, a UK-based PhD student at the Natural Environment Research Council’s Centre for Ecology & Hydrology, investigated whether biochar can suppress soil GHG emissions under field and controlled conditions in a Miscanthus × Giganteus crop, and whether the suppression could be sustained over the next two years. 

Study results show that applying biochar to soil before planting crops can cut soil GHG emissions can by about one-third. Soil plots that had been treated with charcoal emitted 37 per cent less GHG than neighbouring plots that hadn't been treated. In the lab, GHG was cut by 55 per cent, primarily through CO2 emissions.

Apart from wood, biochar can be made out of anything from municipal waste to manure.
