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.
l
Maximum Rate
: The maximum rate of the active ingredient that
should be applied relative to the amount of biomass detected.
Note
: To set the rate based on the desired amount of total
product (as opposed to active ingredient), set the concentration to
100%.
l
Cutoff
: The CropSpec value at which the applicator will stop
applying product. When the CropSpec value is equal to or less
than this value, the application rate drops to zero.
l
Fallback Rate : The application rate that the software should
default to if unable to obtain a valid reading from either sensor.
This can happen if no biomass is detected.
l
Rate Step
: This defines the amount of change of application rate
as the CropSpec value increases or decreases. The values entered
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
