Responsive farming for soil type at Wharminda locations

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
  • Sowing in early June 2009 resulted in wheat yields on 3 soil types being similar but only achieving 50% of potential water use efficiency.
