UPDATE 1 April 2019: The new and improved Graincast™ is now live for the 2019 winter growing season. See here for more information.

Using your local paddock information, national high-resolution satellite and sensor data sources and CSIRO’s innovative analytics, CSIRO’s free Graincast™ app helps your crop decision-making instincts.

Graincast™ uses national weather and soils information to forecast soil moisture and yield for the grain crop planted in your paddock.

Daily rainfall, temperature and solar radiation data are sourced from the Bureau of Meteorology at 5 km resolution. Soil data are sourced from the Australian Soil and Landscape Grid. Soil water status and grain yield forecasts are calculated by the Agricultural Production Systems Simulator, APSIM®, a modular modelling framework developed to simulate biophysical process in farming systems. APSIM® contains a suite of modules that include a diverse range of crops and pastures, and soil processes including water balance and nitrogen transformations.

Graincast™ also uses material sourced from the Queensland Government.

Graincast™ gives you an estimate of the plant available moisture that day and the crop yield potential for the current season for an individual paddock or the farm as a whole at any time. It provides objective information for farmers to make better informed crop and paddock management decisions in near-real-time, like never before.
