Subsoil amelioration – three years on locations
Aims

To investigate yield responses to subsoil amelioration treatments.

Key messages
  • The highest yielding treatments at five of the seven sites were the standard paddock practice where no additional nutrition or deep ripping has been applied.
  • Placing the amendment in the subsoil did not provide any benefit over placing the amendment on the surface.
  • There was little difference in response to applying chicken litter at 20 t/ha or matched rates of synthetic fertiliser.
