Do I need the Atfarm mobile app to use the N-Tester? Where can I find the variety correction lists?

We no longer publish the variety correction lists for the N-Tester. The conversion of the N-Tester reading into a fertiliser recommendation is done exclusively in our Atfarm mobile app. In addition to the variety correction values, other parameters are included in our improved algorithm.

Please install our free Atfarm mobile app from the common app stores on your mobile device to get a nitrogen recommendation after you performed a measurement with the N-Tester.
