- Many operators are not getting the basics right. Conducting annual system checks including pumps, getting the start up time right and avoiding the ‘green drought’ increased productivity by 40% on some sites
- Variable rate irrigation can achieve productivity gains of 30%
- Autonomous irrigation is feasible for dairy and has potential for wider application
- There is a lack of skilled service provider support
On-farm audits of energy efficiency and irrigation uniformity (checking irrigation systems are performing as they were designed to) found big variations in efficiencies – even with recently installed systems.
Monitoring soil moisture, plant condition and weather (especially the weather conditions influencing evapotranspiration) to inform decisions around timing and volume of water applied doubled productivity on some sites.
Smarter Irrigation for Profit was a partnership between the Australian Government and major irrigation industries of cotton, dairy, rice and sugar.

A number of dairy focused research and extension activities formed part of the project:
- Irrigation Scheduling Technologies (plant, soil, weather)
- Smart Irrigation – when and how much. pdf
- Smart Automated Irrigation: Increasing farm profit through efficient use of irrigation for dairy farms
- Improved Flow in Irrigation Bays
- Opimised Dairy Demonstration Sites
Each of these activities is described in more detail below:
Irrigation Scheduling Technologies (plant, soil, weather)
The project developed and tested an automatic irrigation module, based on the satellite/weather-based irrigation information system in Victoria, on commercial dairy sites using flood irrigation as a preliminary step towards the whole farm automation of future irrigated farms in SE Australia. The system combined recent and forecast weather data with satellite imagery to provide local, web based crop and location specific measures of reference evapotranspiration (ETref ) and crop coefficients (Kc) for use in irrigation scheduling.
The project partnered with irrigation automation service providers to demonstrate its ability to provide reliable satellite based irrigation demand triggers to support affordable automated irrigation scheduling on dairy farms in Victoria. Final report:Smart Irrigation – scheduling tools pdf
Smart Automated Irrigation: Develop precise and automated control systems for a range of irrigation systems.
The National Centre for Engineering in Agriculture at the University of Southern Queensland is leading a project to develop precise and automated systems for a range of irrigation systems. The systems will be tested and validated at the field scale, and demonstrated to growers and potential commercial providers to encourage future industry adoption.
The project involves significant development, evaluation, field testing and engagement of potential commercial partners. Field level testing will be implemented at one centre pivot irrigated pasture site in Tasmania, one furrow irrigated cotton field near Wee Waa, NSW, one lateral move cotton site in Dalby, Queensland and one furrow irrigated sugar site in the Burdekin, Queensland. Sites will be monitored to assess both the volumetric irrigation performance and crop yields as well as technical challenges and economic cost benefit. This will assist growers and commercial providers assess the merits of adopting smart automated irrigation systems. Research partners include the CSIRO and the Tasmanian Institute of Agriculture.

Smart Automated Irrigation: Increasing farm profit through efficient use of irrigation for dairy farms
This project, led by the Tasmanian Institute of Agriculture (TIA) used data and autonomous technology to help farmers make informed decisions and improve their efficiency of irrigated water use in pastures.
The project looked at the use of irrigation water in pastures by collecting data on water use, energy use and pasture production from five sites across Tasmania. Using this data, the team worked with farmers to make changes to improve water use efficiency.
The project also trialled an autonomous irrigation system. To do this, the team collaborated with The National Centre for Engineering in Agriculture at the University of Southern Queensland, who have developed a control platform called VARIWise. The VARIWise system has been developed and tested in cotton, but this is the first time it has been applied to a pasture based system. For more information see the project website or , Smart automated irrigation, dairy.

Improving Flow on Irrigation Bays
This project demonstrated to border check irrigators the benefits of an improved irrigation bay design that reduces the duration and variation of surface ponding time.
It aimed to achieve irrigation bays with shorter and more uniform ponding durations, leading to:
- more precise irrigation applications
- more precise irrigation scheduling
- greater production per ML and per ha
- less environmental impact

Optimised Dairy Irrigation Farms
This project supported a network of farmer managed learning sites located in major dairy regions referred to as “optimised irrigation” farms in WA, SA, Gippsland, NSW and Queensland.
Each site tailored the technologies demonstrated based on local needs. Bench marking and measurement of water, energy and labour savings associated with adoption of innovative irrigation technologies was captured over two irrigation seasons. the associated management and skill requirements, maintenance costs and labour and lifestyle implications were also recorded.

Hunter Optimised Dairy Irrigation Farm (NSW)
Glenhaven, located at Aberdeen in NSW’s Hunter Valley will be the focus of the final year for Dairy Smarter Irrigation for Profit. The focus is a 13.5ha centre pivot installed in 2009. The project will seek to identify potential water energy and labour savings at the site. See the site summary and follow the progress here over the coming months.

Scheduling Irrigation Diary for Dairy Pilot
Scheduling Irrigation Diary (SID) is a tool developed by the University of Southern Queensland’s National Centre for Engineering in Agriculture (NCEA), primarily for cropping industries. In partnership, Dairy Australia and NCEA are conducting a small project to investigate if SID has potential as an irrigation scheduling tool in dairy systems and identify the necessary adaptions required for optimal farmer adoption. More information can be found here: Dairy SID Project Promo

Gippsland Optimised Dairy Irrigation Farm
The Gippsland project was based in the Macalister Irrigation District, on the farmer owned Macalister Demonstration Farm (MDF). The farm has four different irrigation systems comprised of surface irrigation, fixed spray, bike shift and sub surface drip, irrigating 72 hectares sown to perennial ryegrass. The Smarter Irrigation project at the MDF is focusing on making the most of existing systems by improving infrastructure and optimising irrigation schedules using soil moisture monitoring technology. Four different soil moisture monitoring systems are being trialled on farm, as well as automation for the surface irrigation system, and improvements to drainage.
An introduction to the project and update on the “Measure to Monitor” project are available:
