摘要: Abstract Dryland salinity increasingly is affecting large tracts of agricultural land in Australia. In response, technologies are being developed to allow farmers make productive use saline land. One option the salt tolerant pasture systems for grazing and localised recharge management. this study, a whole-farm bio-economic model farming system salt-affected region Western Australia applied assess role profitability saltland pastures mixed crop livestock that typifies region. The results analysis show that, across range scenarios, suited moderately environments offer twin advantages improved profit reduced will slow impacts salinisation. practice, an individual farm optimal area likely vary according landscape characteristics market conditions. Key drivers identified, its desirable association with lucerne reduce highlighted priorities future R&D discussed.
