GreenSeeker functionality
As you travel the field, in real-time the GreenSeeker RT200 system:
l Sensors emit light at two specific wavelengths to measure the light reflected by plants.
l Analyzes the reflected light and determines the nitrogen level (NDVI- normalized difference
vegetation index) of the plants below
l Sends the data to the FM-1000 integrated display
The display sends the correct application rates to either:
l The applicator's rate controller (using Serial Rate Control)
l The Field-IQ system
The required amount of fertilizer is applied as you pass over the crop.
As materials are applied, the system logs the:
l NDVI
l Target rate
l Applied rate
Note – Some rate controllers connected via serial cable to the display do not respond with an 'As Applied'
value.
For operational information, see GreenSeeker operation (page 407).
Care and maintenance
To maintain the high performance of your GreenSeeker RT200 variable rate application and mapping
system:
l Each day or during applicator re-fill, check the GreenSeeker sensor detector and light source
windows for dust and dirt, and wipe clean with a soft rag.
l Do not leave the GreenSeeker system outdoors during extreme weather conditions. Wide
temperature variations are hard on electronics and fluid seals, and may reduce the operating
life of the system.
l DO NOT store a GreenSeeker system with the sensors facing upward. Doing so may allow water
to collect around the windows and gaskets, causing seal failures in those areas. Also direct
sunlight can in some cases focus enough energy into the sensor to damage the detector.
Note – There are no field serviceable components of the electronic system. Do not attempt any field repair of
a malfunctioning interface module or sensors. If you experience operating problems, contact your local
dealer.
