Evaluating drip irrigation: Lower Namoi Valley
Drip as an alternative to furrow irrigation on grey cracking clays in the Lower Namoi Valley. Stefan Henggeler
Drip irrigation was installed for a four-year trial period during which the average cotton yield was higher and less water required than previously used under furrow irrigation.
The system performed well with major benefits of substantial water savings (20%-30%) even on heavy clay soils (savings are likely to be even higher in lighter soils), decreased off-target chemical drift, reduced cost in insecticides, reduced need for physical labor, diminished soil erosion and therefore reducing de-silting costs.
For effective use of drip irrigation, diligence in the installation phase is important to ensure it is working effectively to save water, minimize costs and maximise yields.
