|The future prosperity of the irrigated dairy industry depends on our ability to use limited water resources more efficiently. Recent research has shown that replacement of border check irrigation systems with sprinkler irrigation systems may reduce water use, increase production and be cost effective. However:
General access to information about appropriate selection, design and management of sprinkler irrigation systems is not available to farmers, irrigation designers and advisers in Victoria.
There are no measures of the economic and environmental benefits that broad scale use of efficient sprinkler irrigation systems on dairy farms will deliver to catchments. Such information is required for catchment planners to be able to assess the likely impact of policy initiatives related to farm irrigation system infrastructure.
This project was funded through the former Department of Primary Industries, Dairy Australia (external link), Murray Dairy (external link), former Department of Sustainability and Environment (external link), CRC for Irrigation Futures (external link) and it’s objectives are strongly aligned with State Government and Dairy Australia's strategic directions for more efficient use of water.
Research is being focused in Victoria's northern irrigation regions, but methodologies will be transferable to other irrigated dairying regions in Victoria and elsewhere
Centre pivot irrigation
This project aimed to provide information to landowners, irrigation advisers, system designers and catchment planners on the potential benefits arising from adopting more efficient irrigation practices and is working towards producing the following outputs:
Information Booklet summarising recent investigations into the applicability of alternative irrigation systems on dairy farms.
Irrigation System Selection and Design Guidelines - a set of guidelines to provide direction for farmers going through the process of selecting an appropriate irrigation system for their requirements. This will also provide information to designers to ensure that systems are designed to meet the requirements of the dairy industry in northern Victoria. It will include results from this project, and supersede the need for the Information Booklet.
Catchment Planning Information - The package will provide catchment planners with information to assess the benefits and costs of policies related to investment in dairy farm irrigation system infrastructure. The package will contain information that quantifies the seasonal water balance under dairy farm border check and sprinkler irrigation systems for a range of soil and watertable conditions across the Shepparton Irrigation Region. Economic data quantifying the worth of widespread use of sprinkler irrigation systems will also be included.
As information is produced, it will be made available from this webpage or by contacting the project team
Setting up Bowen Ratio equipment for measuring water use in pastures. Field sites will provide information on irrigation performance of border-check and sprinkler irrigation farms.
Wheel rutting is a common issue that results following installation of centre pivot irrigators.
