Abstract
A technique and apparatus for monitoring a plant canopy over a field is disclosed. The technique includes receiving first sensor values from a plurality of plant canopy sensors disposed in or on a ground of the field under the plant canopy. The first sensor values are indicative of near-infrared (IR) light reflected or reradiated from the plant canopy. Second sensor values are also received from the plant canopy sensors. The second sensor values are indicative of red light that is incident through the plant canopy. A map of the plant canopy may be generated based upon the first and second sensor values.
