Yield Prophet for N fertiliser decisions locations
Aims

To determine likely nitrogen response at the time of pre-drilling, and at the appearance of the first node (GS31), which coincided with the times at which nitrogen applications took place.

Key messages
  • APSIM simulations, accessed through the Yield Prophet web interface, were evaluated for their ability to forecast nitrogen fertiliser responses at the canopy management trial in the Wimmera.
  • Yield Prophet accurately simulated crop yield and protein for a range of nitrogen fertiliser application rates and timings.
  • Yield Prophet was able to estimate likely nitrogen fertiliser responses and dollar returns during the season.
  • For accurate simulations Yield Prophet requires good soil characterisation data (crop lower limit, drained upper limit and bulk density) and pre-sowing measurements of soil water and available nitrogen.
