Mixed cover crops for sustainable farming locations
Aims

To investigate mixed species cover crops grown over winter.

Key messages
  • Crop intensive farming systems are running down soil carbon.
  • Mixed species cover cropping offers a new approach that may address the issue.
  • Local guidelines need to be developed so that farmers can make informed decisions about incorporating cover crops into their farming systems.
