In 2013, BIGG initiated a project to monitor soil moisture in local grazing systems (funded by a Caring for Our Country Community Landcare Grant). This involved the establishment of telemetry based weather monitoring stations located in three representative pasture paddocks (Flaxman Valley, Keyneton, Koonunga), which was the first time a farming systems group in Australia has demonstrated soil moisture monitoring in pastures.
In 2019, a fourth station located in a native pasture paddock at Moculta was installed via funding from Adelaide and Mt Lofty Ranges NRM Board’s ‘Supporting Sustainable Primary Production’ grant. Additional support for the project was also received from the AMLR in 2020.
Each station comprises a sub-surface capacitance probe measuring moisture to a depth of 85cm, an automatic rain gauge and sensors measuring air temperature, relative humidity, wind speed, wind direction, NDVI and solar radiation. These are connected to a solar powered telemetry unit that transmits data every 15 minutes via a mobile phone network to an internet server. Data downloaded from the server is then used to produce real-time graphs for each site.
The ‘live data’ from BIGG’s Flaxman Valley, Keyneton, Koonunga and Moculta weather stations can be viewed at:
In 2017-18, BIGG initiated the development of a web-based Pasture Modelling Tool to assist producers in determining their stocking rates through estimating local paddock grazing capacity (through funding from the Adelaide and Mt Lofty Ranges NRM Board and South Australian Murray-Darling Basin NRM Board). The tool is ‘driven by’ the data recorded from the monitoring stations, however additional modelling, including field validation of the tool is required before it can be publicaly released.
A network of soil moisture probes are also located throughout the SA Murray-Darling Basin region. Further further information about their soil moisture status can be accessed here.
