Why isn't a certain crop or variety available for the N-Tester? Can I substitute it with a similar crop or variety?

If a crop or variety isn't available in the Atfarm mobile app for the N-Tester analysis, it means that we haven't collected enough field trial data for a calibration for your region yet. Please stay tuned as we're constantly adding more crop and variety calibrations.


Unfortunately, if you can't find a specific crop or variety, you won't be able to use a calibration from a similar crop or variety instead. Each crop and variety require a specific calibration to ensure the quality of the final nitrogen recommendation.
