How to use the Graincast™ app (beta version)

UPDATE 16 JULY 2018: We thank everyone for their interest in Graincast™. The response has been overwhelming and we are now processing registrations to our beta program as fast as possible. We will accept new registrations for the Graincast™ app in the near future.

Select your paddock

Please check the table below to see whether the app supports last year’s crop for your location. If it doesn’t, unfortunately you won’t be able to use the beta version of the app for that paddock and we suggest choosing a paddock where you grew a different crop.

 Previous crop  Location
 Fallow, wheat  All
 Barley, oats, canola, Lucerne  QLD, NSW, Vic, Tas, SA, WA
 Chickpea, faba bean, field pea, lentil, vetch  QLD, NSW, Vic, SA, WA
 Lupin  NSW, SA, Vic, WA
 Sorghum, maize, mungbean, pasture  Not supported


For Graincast’s™ first release, you will need to send your paddock locations and what crops you grew last season by email to us at Instructions on how to select your paddocks for iPhone and Android are below.

Sometimes we all submit ‘fake’ details to an app or website we haven’t used before to explore what it can do for us. However the functionality of this app could be affected so please send us real paddock locations and the crops you really grew last season.

Access the Graincast™ app

Once we receive your paddock location and last year’s crop by email, we’ll send you access details. When you first use the app, you’ll be asked to provide your consent. You can read our statement on consent, privacy and withdrawing here.

You can save the Graincast™ icon to your home screen for the next time you use it. Instructions are below.

After the first use of the app, you can stay logged in and return to the paddock picker each time you click on the link in your email.

Enter your paddock information

For this version, just click ‘next’ at the paddock picker screen, as we already know the location of your paddock from your email. We also know last year’s crop.

Select the crop you have planted or are looking to plant in the current season.

What Graincast™ tells you

You are then shown:

  • Soil moisture – the plant available water (PAW) accessible by your crop today
  • Yield potential – the forecast range of water-limited yield outcomes for this crop under best management practice. This range reflects the seasonal weather forecast.
