Existing crop yield models typically estimate paddock-scale yields across small areas, or regional-scale yields nationally.  This dichotomy restricts our ability to scale between paddock, region and country yields.  We developed a nation-wide, paddock-scale crop yield model based on satellite imagery, called CCrop.  For its simplicity, C-Crop is effective at estimating canola and wheat yields, with about 70% accuracy.  Ongoing model refinements will improve accuracy, encompass more crop types and perform mid-season forecasting.  Coupled with crop type maps, C-Crop now provides the ability to conduct nation-wide, fine-scale monitoring of Australian grain production.


The Australian Society of Agronomy is the professional body for agronomists in Australia. It has approximately 500 active members drawn from government, universities, research organisations and the private sector.
