SYSTEM, DEVICE AND METHOD FOR ESTIMATING EVAPO-TRANSPIRATION IN PLANTS.

A system for estimating evapo-transpiration from a plant is provided. The system includes (a) a first detector for detecting environmental radiation at a vicinity of the plant; (b) a second detector for detecting air humidity at a vicinity of the plant; (c) a third detector for detecting air temperature at a vicinity of the plant; (d) a fourth detector for detecting boundary diffusion layer resistance at a vicinity of the plant; and (e) a processor communicating with the first, second third and fourth detectors for retrieving data from the first, second third and fourth detectors and for calculating, based on the data a value corresponding to the evapo-transpiration from the plant.
