OptRx uses sensors, usually mounted on the sprayer's booms, to assess reflected light to determine plant vigor. It assigns
numeric values to the varying levels of vigor to create a Vegetative Index (VI). Using the VI, OptRx calculates nitrogen
application rates, to apply a variable rate on the go. OptRx creates nitrogen rates either by using the N Algorithm or by
using the user defined Application Rate Table. OptRx can also be used for scanning purposes.

Attention: Proper care of sensor will ensure accuracy and dependability.
Sensor is designed with a vent (A) to
prevent moisture from accumulating and
damaging the electronics. Use care when
attaching/using/storing sensor, so that
nothing blocks the vent.
Ensure that the optics (B) are not exposed
to direct water and sunlight for extended
periods of time. Because direct sun (UV
light) can be destructive, sensor should be
oriented so that optics face the ground
(even when not in use). To maximize the life
and performance of sensors, they should be removed from equipment and housed in a protective environment
when not in use.

- Page 6 6. OptRx Sensors Apply Variable Rate—The OptRx sensors will apply variable rate N, based on data received from the sensors and the current N Algorithm settings. N Algorithm settings must be reviewed for each application to verify correct inputs are used.
- Page 7 Crop Sensor Settings The Crop Sensor Settings screen is where you can adjust application rate settings specified by the OptRx Crop Sensor module. The VI Zero and Crop Sensor Settings VI Minimum settings are used as a buffer to prevent applying the wrong amount of N or applying it in areas where doing so would be ineffective.
- Page 8 Algorithm implication: The Minimum Rate is the amount of nitrogen the operator wants applied to the healthiest areas of a field. Keep in mind, OptRx may apply very low amounts or zero N if crop appears healthy at the time of application, however the N reserves in the soil may not be adequate to achieve target yield.

- Page 10 Minimum and Maximum Rate have an equal offset from the Planned Rate. The Planned Rate should be set to the intended flat rate to apply if the OptRx N- Algorithm was not used.
