Salinity management practice guidelines 2009-02-04T02:51:00Z 2009-09-14T02:05:10Z Salinity management practice guidelines Managing root-zone salinity for irrigated horticultural crops in winter rainfall zones of Australia Dr Gerrit Schrale, Dr Tapas Biswas Dr Gerrit Schrale, Dr Tapas Biswas 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 salt from the root‑zone is even more important. PN22225 PN22225
