Phosphate efficacy in no-till wheat amended with biocarbon 2013 locations

To investigate targeted biochar use to reduce input costs.

Key messages
  • Banding low rates of biochar can reduce cropping input costs and improve profi tability.  
  • Biochar can improve the effi cacy of fertiliser but should not be regarded as a fertiliser in its own right.
  • More is not better. A rate of around 35kg/ha of biochar plus a modest rate of DAP produced the best economic outcome for all rates of DAP used in the trial (0, 50 and 100kg/ha).
