Corn Setup
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.
North American Wheat Setup
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-Topdress Rate - amount of nitrogen that has been applied in the current year before topdressing.
European Setup
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).
Managed Rate - amount of nitrogen crop will uptake throughout a single season.
Number of Applications - times per season N will be top-dressed.
Planned Rate - intended rate to apply if sensors were not used.
Application Trend - setting telling system whether to Increase rate for High Biomass or Decrease rate
for High Biomass.
