Abstract:

Foliage temperatures measured in proper context with environmental conditions are sensitive indicators of crop water stress. Aerial thermography of the foliage can provide water stress maps of crops, if properly managed. The challenges of aerial thermography for site-specific irrigation are in the measurement and extraction of the relevant canopy temperatures from the thermal image; in determination of the lower and upper temperature limits normalized to ambient conditions; in geo-referencing the results; and in providing useful crop related interpretation. This paper discusses some aspects of the current state of technology involved.
