How soil carbon farming works
Show Notes

Soil carbon sequestration seems like a win for everyone: it improves soil quality, removes CO2 from the atmosphere, and provides an additional source of income for farmers via carbon credits. It forms a major part of the federal government’s plan to reduce emissions to net zero by 2050, with one official estimate suggesting that up to a fifth of our current yearly emissions could be negated with soil carbon. Is it really possible to put such a huge chunk of our emissions in the soil – and if so, how can we do it? What’s holding soil carbon farming back?

Today, Cosmos journalist Ellen Phiddian talks to two experts. Louise Kiely is the Director of Carbon Farmers of Australia, and Dr Michael Crawford is CEO at the Cooperative Research Centre for High Performance Soils. Together, they provide an insight into both the science and legislation around carbon sequestration.
