Soil carbon

Updated 23 January 2015

MAIN POINTS:

  • Soil carbon is about storing more carbon in the soil through improved farming techniques.
  • Soil carbon levels vary a lot in Australia making a methodology tricky.
  • A methodology for grazing systems has been approved but has not been taken up as yet.

THE DETAILS:

Soil carbon is about storing more carbon in the soil through improved farming techniques or land management. This activity could have potential all over Australia. A lot of research has taken place showing there is potential but developing a methodology is tricky - the level of soil carbon changes from one year to the next depending on the conditions and it is difficult to measure without expensive direct measurements.  Some farmers have reported success with techniques like planting native perennial grasses rather than using introduced annual grasses.

A methodology for soil carbon storage in grazing systems was approved in 2014. Because the methodology uses a direct measurement approach, it is not likely to be useful over large areas. So far no projects have been approved under this methodology.
