The potential of the spectral ‘water balance index’ (WABI) for crop irrigation scheduling

Hyperspectral sensing can detect slight changes in plant physiology, and may offer a faster and nondestructive alternative for water status monitoring. This premise was tested in the current study using a narrow-band ‘water balance index’ (WABI), which is based on independent changes in leaf water c...
