Minimum Rate - lowest amount of nitrogen operator wants applied. If OptRx prescribes a lower rate
system will default to the minimum rate.
Maximum Rate - highest amount of nitrogen operator wants applied. If OptRx prescribes a higher rate
system will default to the maximum rate.
Rate Increment - increments of rate change. This setting will be in lbs. of N/ac (kg of N/ha).
Economic Optimal Rate - total amount of nitrogen uptake by the plant over the growing season.
N Credits - amount of nitrogen that is available to the plant in the soil from previous year’s crop and
fertilizer application.
Pre-Sidedress Rate - amount of nitrogen that has been applied in the current year before sidedressing.

V.I. Reference Value
You must scan a portion of the eld and create a V.I. Reference Value.
This V.I. Reference Value is a baseline that the system uses to evaluate the rest of the eld.
Europe - Scan the portion of your eld where the plants show an average amount of vigor and growth.
Scan this area for 150 seconds (2.5 minutes).
Corn and North American Wheat- Scan the most vigorous portion of your eld for 300 seconds (5
minutes). For Corn, a growth stage of V5 or later is needed for accurate application.

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.
The Crop Sensor Settings screen is where you
can adjust application rate settings specied 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.

containing the Map screen’s VI Bar Graph (B),
as shown.
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
Conguration procedure
VI Reference - value of a healthy crop biomass used
in reference for calculating the proper N application
rate
