Biochar and Microbial Signaling: Production Conditions Determine Effects on Microbial Communication
(American Chemical Society, 2013)
Charcoal has a long soil residence time, which has resulted in its production and use as a carbon sequestration technique (biochar). A range of biological effects can be triggered by soil biochar that can positively and negatively influence carbon storage, such as changing the decomposition rate of organic matter and altering plant biomass production. ...
Nitrogen, biochar, and mycorrhizae: Alteration of the symbiosis and oxidation of the char surface
In some cases amending soil with biochar improves fertility, although the exact mechanisms through which biochar alters soil processes are not well understood. In other cases, however, biochar amendment can have no effect on plant growth, or can have negative effects. When crop benefits occur, simultaneous amendment with biochar and mineral nutrients ...
