Does increasing soil organic carbon in sandy soils increase soil nitrous oxide emissions from frain production? locations

To investigate if increasing soil organic carbon (SOC) increases N2O emissions.

Key messages
  • Crop production is often a source of greenhouse gas (GHG) emissions including nitrous oxide (N2O).
  • Increasing organic carbon (C) in the surface soil increased N2O emissions from a cropped soil in the Western Australian grainbelt, however, losses were low by international standards.
  • Greatest N2O emissions occurred in response to summer-autumn rainfall events.
