It is widely recognised that maintaining higher levels of organic carbon improves soil structure, health and function. Increasing soil carbon is also seen as a way to achieve carbon abatement /sequestration, but there is some uncertainty about how much soil carbon will remain in the soil under farming systems, particularly if drying climate trends continue. Land management practices, soil types and periodic climate extremes can make it difficult to build and maintain soil carbon levels in many parts of Australia. This is particularly the case on dryland cropping land, lighter soils and in areas with variable rainfall and extended dry periods.
