Management Zones


You can use pre-existing automated activity layers, machine data or even soil layers as the basis for creating your prescription management zones. By default each one of your fields should automatically have a soil layer assigned to it, however if you don’t it’s also possible to use layer data that’s been uploaded via an RCD data upload.

Creating Prescriptions


How to create a variable rate prescription:


1.  Open the Add Control Center, indicated as a (+) symbol on the far right of the MyFarm horizontal navbar

2.  Under the Add Work menu, select Prescription



3.  Enter your prescription details and select the zone group. The zone group is the field layer that the prescription management zones will be generated from. Hit Next



4.  After you’ve put in the basics, the next screen allows you to assign an activity to the prescription. The Create Activity switch also gives you the opportunity to create a pending activity for the prescription and assigns it automatically into your activity calendar. Once you’ve created an activity, hit Next

5. Select the data layer you’re using for the prescription and hit Next



6.  The next screen allows you to fill in the specifics of the prescription, including the variable rate information for each management zone. Once you’ve filled in the details hit Finish



Hitting Finish automatically creates the prescription, closes the prescription generator and opens the Process Status window that allows you to view the upload status of your prescription layer. Once the upload reaches 100% the layer is now available on the cloud and the variable rate prescription is now logged as a layer on the field.

Closing the Process Status window has no effect on the VRx upload and you can check the upload status at any time by selecting the Process Status option located under the Welcome menu on the right hand side of your MyFarm map screen.


Exporting VRx


Your AgDNA account gives you the option of exporting your farm data in a variety of ways, including the ability to send AB Guidance lines, implement offsets and prescriptions directly to equipment that’s synced to your AgDNA farm.

To export a prescription:


1.  Open the Export tool, located on the MyFarm horizontal navbar



2.  To send your prescription directly to a machine simply choose the type of file you want send, edit the file name and select the Send to Machine option. This will bring up a page that allows you choose the destination of your file

3.  Once you’ve selected a profile name, you can specify the datasets you want included in your export. Toggle the Include Prescriptions switch, select the prescriptions you want to include and hit next

4.  Review the contents of your export and hit Finish
