This project aimed to improve the profit of 3,000 cotton, dairy, rice and sugar irrigators with the support of 16 research and development partners and 19 farmer irrigation technology learning sites. Grower led irrigation research and extension aimed to collect commercially relevant comparative data on different irrigation systems and technologies. The intention was to provide growers improved understanding of the implications for capital investment, management and the resource requirements (water, energy and labour) associated with different irrigation systems and the adoption of automation technology and different approaches to farming systems.The project consistedof three components. 1.Practical, reliable irrigation scheduling technologies 2.Precise, low cost automated control systems for a range of irrigation systems3.A network of 19 farmer managed learning sites located around Australia.The project hadkey learning sites in Queensland; Ayr, Emerald, Warwick, Dalby, Toowoomba, St George. NSW; Moree, Narrabri, Wee Waa, Tamworth, Aberdeen, Whitton, Jerilderie. Victoria; Numurkah, Shepparton, Macalister. Goulburn Murray Irrigation District,Tasmania; Rocky Creek, Sisters Creek, South Riana, Montana, Cressy. South Australia; Allendale, Eight Mile Creek, Mt Schank. Western Australia; Harvey.The flagship strategy of the project was use of the key learning sites. These 19 sites were located all around Australia and were mostly on commercial farms. They all involved farmers, advisers, scientists and agribusiness. Thousands of people inspected or visited one of these sites. Some were more “research” focused; testing a hypothesis with robust scientific methods. Others were “demonstration” focused involving monitoring current actions and making changes as experience and confidence grew. One of the strengths of the project was having both approaches.Extension activities conducted by the project have resulted in the project being promoted to over 3000 irrigators and industry personnel at a range of field days, field walks and workshops.Severalactivities targeted sharing knowledge and collaborations across different sectors of rice, cotton, sugar and dairy. These included bus tours to other industries, social media, workshops and farm field days
