Modelling soil organic carbon changes in cropping and grazing systems locations
Aims

This project explored the extent to which various crop and pasture management options effected changes in SOC, from sub-tropical to temperate environments. 

Key messages
  • The difference in soil organic carbon (SOC) changes between nine sites across eastern Australia was largely characterised by mean temperature and rainfall.
  • High temperature strongly interacted with management practices (stocking rate, nitrogen application and residue incorporation) to reduce carbon sequestration despite favourable rainfall.
