Salinity impact on Lower Murray horticulture 2008-02-01T05:14:52Z 2009-07-16T01:53:05Z Salinity impact on Lower Murray horticulture <p>The project was developed to test the hypothesis: &lsquo;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&rsquo;s LE and its variance&rsquo;. The specific objectives were to:</p> <ul> <li>Determine/update the salinity relationships for irrigated horticulture along the Lower Murray: Riverland, Sunraysia and western NSW;</li> <li>Determine the variability of EC (soil water) and leaching efficiency in the field under known soil conditions and irrigation management;</li> <li>Simulate the performance of horticultural crops under different scenarios of River Murray salinity at Morgan; and</li> <li>Provide input to the implementation of the Salinity Strategy and Integrated Catchment Management Plan of the Murray-Darling Basin.</li> </ul> PR082003 PR082003
