In the grainbelt livestock have to be returned to help restore the carbon cycle. Millions of tonnes of CO2 are released every year as stubble windrows are burnt to control weeds and entire paddocks are burnt to try to mitigate frost. These practices have to stop. If the stubble windrows were pyrolysised and the BC was returned to the soil then soil quality and moisture retention would improve and soil OC decline would be reversed. The technology is available, all that is lacking is a good reason and the motivation.
