Can biochar help suppress greenhouse gases? http://apocadocs.com/s.pl?1300538213
Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are responsible for an increase in nitrous oxide emissions from grazing animals' excrement. Biochar is potentially a mitigation option for reducing the world's elevated carbon dioxide emissions, since the embodied carbon can be sequestered in the soil. Biochar also has the potential to beneficially alter soil nitrogen transformations.
Laboratory tests have indicated that adding biochar to the soil could be used to suppress nitrous oxide derived from livestock. Biochar has been used for soil carbon sequestration in the same manner....
Addition of biochar to the soil allowed for a 70 percent reduction in nitrous oxide fluxes over the course of the study. Nitrogen contribution from livestock urine to the emitted nitrous oxide decreased as well. The incorporation of biochar into the soil had no detrimental effects on dry matter yield or total nitrogen content in the pasture.
