Site description, objectives, monitoring infrastructure, and the science behind SMART Irrigation.
The SMART campaigns are conducted at a farm near Newry, located in the central Gippsland region of Victoria, approximately 210 km east of Melbourne. The Gippsland region (41,556 km²) is known for its stable climate, strong rainfall, and productive arable soils — hosting dairy, grain, fodder cropping, and horticultural industries.
The study area is an approximately 400 m diameter centre-pivot irrigation site (146°51′19″–46″E, 37°54′14″–38″S), monitored by Agriculture Victoria as a precision agriculture core site since 2016.
Overview of crop conditions at Newry farm from 2024 to 2025, with UAV flight dates marked for each campaign.
Develop a high-accuracy algorithm to convert UAV PLSR brightness temperatures into 10 m resolution near-surface soil moisture maps across entire agricultural fields.
Integrate surface soil moisture maps with the SWAN Systems water balance model to predict root-zone soil moisture evolution and derive optimal irrigation demand maps.
Close the loop by driving the centre-pivot irrigation heads with model-derived prescription maps, demonstrating real water savings and improved crop productivity.
Installed October 2023, distributed to capture the full wetness gradient across the study area.
