When the CropSpec value is greater than or equal to the threshold
value the application rate will be at the minimum.
4.3.3. Configuring Two Point prescription
For this prescription type, the average CropSpec reading for both
poor crop health and good crop health is required.
1. Drive through the parts of the field where crop health is poor to
acquire the average reading for poor crop health (Crop Sense A).
2. Drive through the parts of the field where crop health is good to
acquire the average reading for good crop health (Crop Sense B).
Refer to Recording CropSpec readings, page 19 for details on
recording average CropSpec readings.
The two average readings are used to automatically generate a slope
that defines the change in application rate with respect to the change
in CropSpec value between the two readings.
Enter the following data values to complete the configuration:
l Concentration %: The ratio of the active ingredient in the
product being applied (nitrogen if Nitrogen Content based
Mass/Area selected in output configuration, see page 14).
l Minimum Rate: The minimum rate of the active ingredient that
should be applied relative to the amount of biomass detected.
