for minimum and maximum rate are rounded up or down to the
nearest multiple of the value entered for Rate Step, effectively
changing the minimum and maximum rate. To prevent this, the
value entered here should be a multiple of the minimum and
maximum rate values.
l Crop Sense A: The average CropSpec reading for the field. For this
example, average Crop Sense A is 40.
l Rate A: The application rate when the CropSpec reading matches
the value of Crop Sense A.
l Slope: The change in application rate with respect to the change in
CropSpec value. Positive slope will increase application rate as
biomass reading increases and negative slope will decrease
application rate as biomass increases.
Note: A negative slope value is usually required.
Note: If you are unsure what this number should be, please consult
with a qualified agronomist.
4.3.5. Configuring Target Rate prescription
Note: Histogram recording must be active for this mode to operate.
Refer to page 16.
Target Rate mode is very similar to One Point plus Slope. Instead of a
fixed CropSpec value reference point, it uses the live field average
determined automatically as the CropSpec system is processing the
field. Gradually the system finds the average CropSpec parameter and
varies the application rate based on this parameter.
The entered Target Rate is linked to the CropSpec field average. If the
live CropSpec value is equal to the field average, the application rate
will be the entered Target Rate. If the live CropSpec value is greater or
less than the field average then the application rate will adjust
accordingly. Note the field average is continuously updated hence the
line on the graph shifts left/right as the field average changes.
