This @CSIRO #Graincast forecast of the national wheat yield harvest is based on data up to 1 Sept 2021. The median forecast is 2.09 t/ha with a 97% chance of exceeding the 15 year average of 1.79 t/ha. For more detail and state by state forecasts visit research.csiro.au/graincast/…

It's the 20th of April, so time to start tweeting the #CSIRO #Graincast wheat yield forecasts for 2021! We've added a few bells and whistles for this season: maps of soil water, water-limited yield forecast (see map) and their uncertainty as well as state specific forecasts.
ALT Map of Plant Available Soil Water (PAW) in Australia's grain zone on the 15th of April 2021. The map assumes that there was a healthy crop in 2020 and that the field has been weed free, zero tilled and stubble was retained.
