Managing stubble and fertiliser to increase soil carbon locations
Aims

To add normal, as required to optimise yield potential, and extra amounts of nutrients (N, P and S) to different stubble managements (intact, incorporated and removed) to see if SOM levels could be increased.

Key messages
  • The addition of extra nutrients and stubble management (removed, incorporated or intact) did not affect grain yield or soil carbon stocks after three years of trial work.
