For over 30 years, the Centre has been working with industry to develop more sustainable and efficient ways of using water sustainably to grow crops and support the environment. Irrigation research is conducted across a wide variety of agricultural industries nationally and internationally.

Title: Automated Broad-acre Irrigation Optimisation
UniSQ’s Centre for Agricultural Engineering is completing research on broad-acre surface irrigation, large centre pivots and lateral moves, to automatically optimise irrigation events with novel technologies developed by our Irrigation & Water Management team.

Title: Dry Season Irrigation for Marginal and Tenant Farmers
Leader: Erik Schmidt
Project Team: Michael Scobie | Lidya Agustina | Dr Jochen Eberhard | Ralph Shippam | Rupak Sarkar, UBKV (North Bengal Agricultural University) | Mohammad Mainuddin, CSIRO | Santosh Mali, Indian Council for Ag Research
Project Partners: IWMI, International Water Management Institute
Funding Body: ACIAR Australian Centre for International Agricultural Research
UniSQ’s Centre for Agricultural Engineering is supporting irrigation development in the Eastern Gangetic Plains, which include the Nepal Tarai, Bihar and West Bengal regions, and is one of the most densely populated, poverty-stricken belts in South Asia. The Australian Centre for International Agricultural Research is investing in research aiming to improve the livelihood of women, marginal and tenant farmers in the Eastern Gangetic Plains, through improved water use and increased dry season agricultural production.

Title: Direct one-step measurement of broad-acre crop evapotranspiration
Direct one-step measurement of water vapour flux from broad-acre irrigated cropping is a focus research area for the Irrigation & Water Management team at UniSQ’s Centre for Agricultural Engineering. The Cotton Research and Development Corporation is supporting this post-doctoral work of Dr Simon Kelderman to further refine sensor selection and deploy his novel system in commercial fields to allow industry to obtain direct crop evapotranspiration rates.

The largest loss of water in the northern Murray-Darling Basin is the evaporation and seepage from on-farm water storages, and the Irrigation & Water Management team at UniSQ’s Centre for Agricultural Engineering remains keenly focussed on this “wicked” problem. The Cotton Research and Development Corporation is supporting this work to determine alternatives and further refine real commercial options for regional water managers across Australia to reduce this stored water loss.

Title: Demonstrating and integrating irrigation technology for cotton
Project Lead: Assoc Prof Joseph Foley
Project Team: Assoc Prof Joseph Foley, Dr Jochen Eberhard
Project Partners: CRDC – Cotton Research and Development Corporation
Funding Body: CRDC – Cotton Research and Development Corporation
Project focusses on enhancing the uptake of advanced irrigation management technology across irrigated grower communities with a three-pronged approach for: actively engaged grower cohort through demonstration and peer interaction, dedicated on-farm agronomic service providers who are continuing to seek more understanding of these irrigation technologies, and industry’s very active extension networks busily dealing with a wide range of broad industry challenges.

Title: Advanced Field Sensing
Project Lead: Assoc Prof Alison McCarthy
Project Team: Assoc Prof Alison McCarthy, Dr Derek Long, Dr Yiyi Xiong, Dr Jochen Eberhard
Project Partners: CRDC – Cotton Research and Development Corporation; Department of Primary Industries
Funding Body: CRDC – Cotton Research and Development Corporation
Development of a novel suite of automated machine vision tools that reduce reliance on workforce labour for agronomic scouting to potentially increase productivity and improve crop management decisions involving pests, crop growth, crop rotations, patch management and irrigation scheduling. The project will be delivered by engineers at UniSQ, and agronomists, entomologists and pathologists at QDPI.

Title: The Australian Cotton Disease Collaboration (The ACDC) - Irrigation and nutrition management to reduce cotton wilt disease incidence and machine vision system development to detect and differentiate verticillium and fusarium wilts
Project Lead: Assoc Prof Alison McCarthy
Project Team: Assoc Prof Alison McCarthy, Mr Isaac Halling, Assoc Prof Joseph Foley
Project Partners: CRDC – Cotton Research and Development Corporation, Department of Primary Industries
Funding Body: CRDC – Cotton Research and Development Corporation, Queensland Department of Primary Industries
The expected industry outcomes and impact are that Australian cotton growers will have an improved understanding of the interactions between irrigation, nutrition and disease incidence for Verticillium and Fusarium wilt in both furrow and surface irrigation systems. This will contribute to reduced yield loss through understanding improved wilt. management options, increased water use efficiency when irrigating with a higher soil water deficit and increased profit through reduced fertiliser application and reduced disease incidence.

Title: Advancing the adoption of climate-smart, innovative irrigation control technology for the cotton and dairy industries
Project Lead: Assoc Prof Alison McCarthy
Project Team: Assoc Prof Alison McCarthy, Assoc Prof Joseph Foley
Project Partners: CRDC – Cotton Research and Development Corporation; Ag Logic; Swan Systems; University of Tasmania
Funding Body: CRDC – Cotton Research and Development Corporation
This project will transition an innovative precision irrigation optimisation and control system, VARIwise, from proven proof-of-concept to a commercial-ready package. VARIwise can deliver 10% in water savings and 5% productivity improvements in cotton and pasture significantly increasing the climate resilience of irrigators and reduce emissions from water logging. It represents a step change in water use efficiency gains and will assist industries demonstrate their water sustainability credentials. The project will address the barriers to adoption of precision technologies by working with commercial technology providers and consultants to develop VARIwise into a format that can easily interface with any on-farm sensor and irrigation system. Non-exclusive commercial access will maximise adoption. The project includes on-farm demonstration activities led by irrigation technology consultants and the consortium will engage with industry extension teams to deliver communication activities. This research is funded from Australian Government Climate-Smart Agriculture Program’s Partnerships and Innovation Grant and led by CRDC in partnership with irrigation technology provider SWAN Systems, precision agriculture advisory business Ag Logic and University of Tasmania.

Title: Water balance scoping study for Northern NSW/Queensland
Project Lead: Assoc Prof Joseph Foley
Project Team: Assoc Prof Joseph Foley, Dr Malcolm Gillies, Dr Simon Kelderman
Project Partners: CRDC – Cotton Research and Development Corporation
Funding Body: CRDC – Cotton Research and Development Corporation
A desktop scoping study for research into the measurement techniques for a full season water balance of siphon-less broad-acre irrigation systems is to be conducted. A review of siphon-less irrigation system designs most commonly deployed across Northern NSW/Queensland will be completed through interaction with key designers and leading growers.
