Responsive farming using variable rate sowing at Minnipa locations
Aims

To manage risk through variable rate technology using different inputs over variable soil types and testing the use of Yield Prophet to match plant available water and nutrition with modelling of climatic conditions, knowing that we can have unpredictable finishes to seasons.

Key messages
  • The profitability of VRT, excluding capital outlay, was just better than standard practice over the last two seasons at Minnipa.
  • The long term impacts of reducing inputs and any consequent yield reductions in above average seasons are yet to be determined.
