Abstract
Increasing soil carbon storage in extensive grazing systems in temperate regions Degraded soils in extensive grazing systems have the potential to sequester significant amounts of carbon, and in doing so improve productivity and long-term sustainability. In this study we are investigating the effect on soil carbon of a range of commercially practicable grazing and pasture management strategies that aim to increase the persistence of perennial pasture. The strategies that have been implemented on farms across northern and southern Tasmania include: different periods of rest via rotation or exclusion of livestock; sowing of perennial pasture species; rehabilitation with native pasture and tree species; and application of organic amendments. For each trial site total and labile carbon is measured and a cross-fence comparison done with normal farm management. This Carbon Farming Initiative, Action on the Ground project, is undertaken in collaboration with two NRM regions, Greening Australia and with co-operation from a major private agricultural service provider and the State Government. The results of the on-farm demonstration trials will be applicable to producers utilising dryland pastures for meat and wool production. We will present initial findings from field work and existing datasets.
