Getting Graincast™

When you first start using the Graincast™ app, you will be asked to provide your consent. You can read more on consent, privacy and withdrawing here.

Selecting your paddock

You can add paddocks by clicking the white/red plus icon in the bottom left of the screen.

You can view a list of paddocks by clicking the white/red list icon next to the plus.

Clicking on a paddock name allows you to rename it.

Selecting your crops

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 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

If last year’s crop is supported, select it and the crop you have planted or are looking to plant in the current season.
