Changing Irrigation Systems and Management in the Harvey Irrigation Area

Milestone Report - End of Stage 1 - February 2004

The project is examining issues of water use efficiency (WUE) in the South West Irrigation Area (hereafter called the Harvey Irrigation Area). A significant WUE issue is whether water savings, improved pasture yields and farm productivity can be achieved through sprinkler (centre pivot) irrigation of dairy pasture in comparison with traditional surface bay irrigation (often called flood irrigation). This project is a case study conducted on (more)...

Using Wetting Front Detectors in Furrow Irrigation

The Wetting Front Detector (WFD) is a new tool to help measure how deeply water has penetrated into the soil after an irrigation event. The WFD also captures and stores a soil water sample, which can be analysed for its salt or nutrient content. The first commercial version of the Wetting Front Detector (WFD), called the FullStop, was released in 2004. The FullStop WFD is comprised of a (more)...

Measuring the effects of improving water use efficiency on root zone salinity

Research Bulletin 1

Since the end of 2003 a tri-state syndicate of government agencies from western NSW, Victoria and South Australia has been working on a strategy to manage this salinity hazard. This Research Bulletin draws on some of the findings to date, focusing on results of monitoring root zone salinity and deep drainage in sprinkler and drip-irrigated citrus orchards and vineyards.
