GreenSeeker operation 18 Operations
Variable rate setup
To set up variable rate application on the display:
1.
Power up the RT200 interface module and the rate controller (if required).
When the RT200 interface module is first powered on:
a. The module's green power LED will blink three times accompanied by three beeps.
b.
The status LED will blink in time with each transmission of sensor data over the CAN bus.
Expect to see a brief green flash, followed by a red flash at the I/M message rate (typically
at 0.5sec). This indicates that data from the left (green flash) and right (red flash) CAN ports
is being transmitted.
2. Activate GreenSeeker for use. See Activate features/plugins for use (page 47).
3.
At the Home screen, tap .
4. At the Configuration Selection screen, tap OK.
5. At the Field Selection screen, load the field to be sprayed.
Create a custom table
Historical knowledge about the crop enables growers or crop consultants to determine different
crop input requirements based upon biomass/size of the crop/plant. An example of this type of use
would be variable rate application of:
l Defoliant in cotton
l Desiccant in potatoes
For these cases, the field is scouted (field calibrated) to determine areas of the field that require
different rates of defoliant.
To obtain the NDVI values in representative areas of the field, you can use either:
l The RT200 system
l A GreenSeeker handheld
Using this data, you can create a table with NDVI values corresponding to application rates.
To create a custom table:
1. At the GreenSeeker Calibration screen, tap the Algorithm tab.
2.
From the Formula list, select either:
Custom Table: Manually enter NDVI calibration values (go to step 4)
