Press the OptRx prescription rate button
in the Product Control Toolbox to engage
the OptRx system to apply variable rate N,
based on data received from the sensors.
This variable rate is shown on the Product
Control Toolbox tab.
VI Zero - threshold below which the Crop Sensor
applies a zero rate, used to prevent applying N over
bare ground or permanently damaged crops, enter
value with keypad or enter in current value using Set
to Current button
VI Minimum - threshold below which the Crop
Sensor applies minimum rate, setting used to apply
a minimum amount of N on ground with damaged
crops, may enter value using keypad or enter in
current VI value using Set to Current button
Reference Strip - name entered during the
Configuration procedure
VI Reference - value of a healthy crop biomass used
in reference for calculating the proper N application
rate
Algorithm Settings - access Setup screen to adjust
setup rates (discussed on page 2)
The Crop Sensor Settings screen is where you
can adjust application rate settings specified by
the OptRx Crop Sensor module. The VI Zero
and 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.
To access the Settings screen, press the
OptRx Crop Sensor button, located in the box
containing the Map screen’s VI Bar Graph (B),
as shown.
