The project was developed to test the hypothesis: 'a depressed leaching efficiency (LE) in the Lower Murray irrigation districts raises the root zone salinity and, improved water use efficiency (WUE) has an upper limit determined by that field's LE and its variance'. The specific objectives were to: Determine/update the salinity relationships for irrigated horticulture along the Lower

The FullStop Wetting Front Detector was designed to be a simple, inexpensive and robust device that gives a yes/no response to whether a wetting front has reached a particular depth. When searching for simplicity and low cost, tradeoffs need to be made with sensitivity; in the case of FullStop the decision was made to detect a 2 kPa strength wetting front. From a theoretical perspective, the FullStop Wetting Front Detector is not well suited to furrow irrigation, deep placement, cracking

The emphasis in this document is on water use efficiency and the productive use of water in an agricultural context. Other uses (e.g. the maintenance of wetlands) are important, but are better assessed by other indicators.

* Sustainable Irrigation Project wins WA award * Research topics scoped for Program priorities * Falivene wins travel fellowship * Government confirms continued funding

The National Program for Sustainable Irrigation was a unique collaboration as it involved governments, irrigators, water providers and researchers from across Australia. It covered every aspect of irrigation from dam management and water delivery, through on-farm management, to sustainable landscape environmental measures
