Thanks to support from John Deere, these maps are produced as close to real-time after rainfall is recorded at more than 1000 real-time rain stations across the country.
The STIN crop model is used by Agrometeorology Australia to produce a soil moisture ranking map by shire.
Crop yield rankings dropped further across Australia during September, particularly in Western Australia and central and southern New South Wales where decile 1 (lowest 10% of records in 100 years) September rain fell.
The only increase in rankings occurred in the Eyre Peninsular and the Tatiara region close to the western Victorian border with both areas receiving favourable rainfalls during the past month.
In far northern New South Wales and Queensland, rankings are now finalised for the year and many shires have fallen into the lowest five per cent in 100 year ranking - a serious scenario given this is the third year of drought in this region
Farming Ahead will continue to publish these maps online at the beginning of each month with the final installment in November.
