Description

The principle behind thermal imaging is based on the fact that plants under water stress have a lower transpiration rate and a higher canopy temperature than plants well supplied with water. Canopy temperatures captured by drone can be used to quickly evaluate water stress in crops like lowbush blueberries and guide decisions as to whether irrigation is required.
