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
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.
VI Zero
— The threshold below which the Crop
Sensor applies a zero rate. This setting is used to
prevent applying N over bare ground or
permanently damaged crops.You may enter in a value either by pressing
, or you may enter in the current VI value
by pressing
.
VI Minimum
— The threshold below which the Crop Sensor applies the minimum rate. This setting is used to apply a
minimum amount of N on ground with damaged crops.You may enter in a value either by pressing
, or you may
enter in the current VI value by pressing
.
÷
The minimum rate may be adjusted at the Crop Sensor screen, which is accessed by pressing the
Algorithm
Settings
button.
Reference Strip
— The name of the Reference Strip that you entered during the scanning procedure.
VI Reference
— Value of a healthy crop biomass used in reference for calculating the proper N application rate
Algorithm Settings
— Press this button to access the Sensor Setup screen, where you can adjust the inputs used by the
N Algorithm to calculate to optimal Nitrogen rate. Without a valid Reference Strip this button will not be active. Please refer
to the Crop Sensor Setup section below for information on how to decide on what inputs to use for the N Algorithm.
