Precision irrigation is essential in arid and semi-arid regions facing limited water reserves. This has led the scientific community to develop new technologies for irrigation management to streamline the water supply to the needs of culture to fit production targets. Among these, water stress indicators measured directly on the plant have shown the greatest potential. Thus, measurements of leaf water potential, canopy temperature, sap flow, or variation of trunk diameter, among other variables, have proven useful not only for research purposes, but also for applications in commercial vineyards. In association with spatial extrapolation models based on medium or high resolution auxiliary data (δ13C, NDVI, etc.) these methods can be used to control irrigation taking into account the spatial variability of plant water status over the vineyard.
