China can make staple crops carbon-negative by adding biochar to soil

Researchers calculate that different farming practices may flip staple crop manufacturing right into a carbon sink and enhance crop yields in China if adopted en masse

China’s manufacturing of staple meals crops resembling wheat and corn may develop into a web carbon sink if farmers begin making use of biochar to soils en masse.

Instead of returning uncooked biomass, like straw, again to the soil on the finish of the rising season, farmers may take it to pyrolysis vegetation, the place the biomass is heated at a really excessive temperature in an oxygen-free chamber to create biochar.

Biochar is a type of stable charcoal, and research have proven that making use of it …
