Besides feeling the soil and sniffing the air, farmers can now point gun shaped infrared meters at
their crops in order to discover when the plant; need watering. These portable meters give digital
readouts that indicate the difference between a plant's temperature and
that of the surrounding air
When it is short of water, a plant, which
normally uses evaporation as ; means of cooling, cannot rid
itself of the heat it absorbs from sunlight on the heat that may build up from its own metabolism.
Hence, if the meter indicates that
a plant is warmer than the air, it may mean that it is time to irrigate.
