Farmers leading and learning about the soil carbon frontier
Summary
The DAFF and GRDC funded national trial will examine existing, new and alternative strategies for farmers in the cereal sheep zone to increase soil carbon.
The trial will be used as baseline data for carbon accumulation in soils and to:
- discuss the various forms of soil organic carbon (plant residues, particulate, humus and resistant fractions),
- investigate how management affects each of these pools and how humus can be increased over the medium to long term,
- communicate how soil organic matter affects soil productivity (through nutrient and water supply, and improvements in soils structure).
Identical trials are being run by eight farm groups in SE Australia (Victoria: Mallee Sustainable Farming, Birchip Cropping Group, Southern Farming Systems; NSW: FarmLink, Central West Farming Systems; SA: Hart and Eyre Peninsula Agricultural Research Foundation, both through Ag Ex Alliance; and Tasmania: Southern Farming Systems) so information can be collected on different soils and climates in the Southern Region.
