Farming to soil potential on the Upper Eyre Peninsula: how accurate was in-season yield prediction in 2009? locations

To test whether knowledge of soil potential, soil variation and in-season predictions of grain yield with Yield Prophet could be useful to improving management.

Key messages
  • Using crop growth models to quantify the season to season yield performance on different soil types and predict in-season potential yield can be a very useful tool for managing risk and inputs.
  • Given the high spatial variability in soils and grain yield, mapping paddocks into zones of similar soil and yield potential enables farmers to better target input levels as well as understand crop yield potential in different seasons.
  • Information about the capacity of a soil to hold water, the water and mineral N levels at sowing are the basic information needed to use Yield Prophet - given this information, grain yield can be accurately predicted.
