Abstract | Automated irrigation and fertigation site-specific control systems offer labour and water savings, and crop productivity improvements for growers, where spatial variability of water requirements exists within a field. Real-time irrigation control strategies for surface and pressurised irrigation systems have been developed that adapt to infield soil and plant measurements collected in real-time. 'Sensor-based' control strategies directly use measurements to make irrigation decisions; and 'model-based' control strategies use a model (often calibrated with sensor input) to aid irrigation decisions. Model-based control strategies can aim for specific end of season characteristics. However, model-based control strategies often use off-the-shelf, black box industry models that may not be updated with the development of the new varieties, and may not consider all the soil-plant-water relations. |
