Claim 8:
9. A method of measuring a plant health parameter comprising one or more of: a level of moisture in a plant canopy, a biomass of a plant canopy, a cellulose content of a plant canopy and a level of stress of plants comprising a plant canopy, the method comprising:
using a measuring device, measuring a measured infrared (IR) parameter value at a measuring wavelength at which the measured IR parameter value is sensitive to variations in the plant health parameter for a measuring path extending through the plant canopy;
using a processor, comparing the measured IR parameter value with the reference IR parameter value to determine a relation between the measured IR parameter value and the reference IR parameter value; and
using a processor, determining one or more of: the level of moisture in the plant canopy, the biomass of the plant canopy, the cellulose content of the plant canopy, and the level of stress of the plants comprising the plant canopy based on the relation between the measured IR parameter value and the reference IR parameter value.
