China’s production of staple food crops such as wheat and corn could become a net carbon sink if farmers start applying biochar to soils en masse.
Instead of returning raw biomass, like straw, back to the soil at the end of the growing season, farmers could take it to pyrolysis plants, where the biomass is heated at a very high temperature in an oxygen-free chamber to create biochar.
Biochar is a kind of solid charcoal, and studies have shown that applying it …
