Yield Prophet Lite

Yield Prophet Lite is a free tool that lets you estimate potential yield values for your crop given different rainfall amounts and fertiliser application rates. Yield Prophet Lite calculates water-limited yield potential using the Sadras and Angus (2006) formula. It also uses the POAMA/ACCESS model to give the rainfall likelihood for the remainder of the growing season.

You can specify your crop from wheat, barley, canola or oats, choose your closest Bureau of Meteorology weather station, and input some quick details about your rainfall, nitrogen applications and soil organic carbon. Yield Prophet Lite will calculate a range of yield potentials and nitrogen-limited yield potentials for your crop, and tell you the likelihood of different future rainfall amounts for the rest of the growing season based on the POAMA/ACCESS model.
