Access through your institution Buy or subscribe To optimize the agricultural and environmental benefits of biochar, a charcoal-rich soil additive, we need to overcome its potentially


undesirable effects (see _Nature_ 517, 258–260; 2015). For example, it is uncertain whether biochar — effectively an underground carbon store — can help to mitigate carbon emissions. A


ten-year study of boreal forests found that applying biochar led to soil degradation and increased the activity of soil microbes, causing carbon dioxide release (D. A. Wardle _et al_.
