Soil moisture mapped during seeding period

Author: Sharon Watt | Date: 11 May 2015

Grain growers in the southern cropping region can access useful soil moisture maps thanks to the Australian Export Grains Innovation Centre (AEGIC) which is regularly publishing updated maps during the winter crop sowing period. The maps use rainfall data from more than 900 Bureau of Meteorology weather stations across Australia and can be viewed via the AEGIC website.

The Australian soil moisture ranking percentile map displays the ranking percentile for this year compared to the previous 99 years, at the same day of the year. The plant available soil moisture map displays the soil moisture in millimetres (mm). Soil moisture is calculated using a fallow evaporation model based on the Ritchie water balance model. The calculation does not account for plant water-usage by summer crops or weeds.

Throughout the growing season, AEGIC also produces Crop Prospect Reports and Yield Prediction maps by shire. The dates of release of these maps can be viewed at on the AEGIC website, and growers can email if they wish to receive these products.

The AEGIC was established in November 2012 by the Grains Research and Development Corporation (GRDC) and the Western Australian State Government (through the Department of Agriculture and Food, WA). AEGIC supports the trade and use of Australian grains around the world through cutting-edge grain quality and processing technology and market research innovation. AEGIC also provides seasonal yield predictions and other weather-related tools to assist growers with sowing, crop management and marketing decisions.
