Whopper Cropper and seasonal forecasting
Whopper Cropper enables crop management advisers to predict the likely distribution of crop yields for the upcoming season, based on starting soil conditions and knowledge of the current phase of the SOI. APSIM has been used to simulate a range of management options based on around 100 years of historical climate data.

The 100 year simulations of crop yields can be divided into groups of analogue years in which the SOI phase in a particular month was the same.

Distributing simulated yields by SOI phase enables crop management advisers to discuss with farmers the best management options for the coming season.
