How much Soil Organic Carbon is best?

David Johnson’s excellent talk tackles this very question.

His finding correlates very well with my own readings on soil organic carbon (SOC) reaching a tipping point along with fungal diversity at about 3-4% SOC. 97 more words


geoengineering explained: the benefits and challenges of biochar

Biochar, a form of carbon dioxide sequestration (SDR), is a solid material obtained from the carbonization of biomass. This produces a highly porous charcoal. The biomass is then buried in order to lock the carbon into the soil which can improve soil functions and the CO2 typically produced by the natural degradation of biomass is reduced. 205 more words
