Salinity management practice guidelines

Managing root-zone salinity for irrigated horticultural crops in winter rainfall zones of Australia

A better understanding of plant requirements and the highly efficient management of water has led irrigators to apply water to accurately meet crop needs. This has meant a considerable reduction in the amount of water flushing through the root-zone. As a result, soil salinity levels have risen. Current drought conditions and low water allocations are likely to result in even less water being used to flush salts from the root-zone. The declining quality of water resources means that actively removing (more)...

Root Zone Salinity Risks in the Lower Murray Districts

As a result of improved irrigation management and systems, growers in the Lower Murray (Riverland-Sunraysia) horticultural region have improved their water use efficiency (WUE) over the past two decades from about 50% to about 80%. However a negative consequence of this achievement is the emerging risk of salinity build-up in the root zone, threatening the sustainability of the region (Biswas et al. 2005a; Biswas et al. 2005b). The amount of irrigation applied must account for (more)...
