Advances in sensor technologies for in-field monitoring of plant's water-stress

To optimize usage of water resources utilized for irrigation, direct plant-based measurements become increasingly important in determining the exact water-demand. Plant-physiology has made significant progress in understanding vascular plant's water transport mechanisms and plant's physiological responses to seasonal droughts, including their defense strategies, characteristic water-stress symptoms, and vulnerability- thresholds defining points of no return. However, experimental plant-hydraulic research often requires instrumentation impractical for field- deployments in precision agriculture. Trying to bridge this gap between laboratory and field, this session explores emerging sensor technologies and instrumentation enabling autonomous, non-invasive, low-power monitoring of key plant-hydraulic quantities, useful for integration in future precision-irrigation systems. We will focus on thermal sap-flow measurement techniques, and on passive ultrasonic monitoring of xylem embolization processes.
