Challenge

A 220-acre field in Minnesota averaged 217 bushels per acre the year before and after tiling a portion of the field, but that yield average dropped the next two years to 186 and 159 bushels, respectively. The team needed to understand what was driving the decline.

How TerrainIQ Helped

Using TerrainIQ, they overlaid their yield data and tile map, revealing that inconsistent performance was concentrated in untiled portions of the farm.

Outcome

The data revealed that the whole-field average was being pulled down by specific untiled areas, giving the team a clearer path for future drainage improvements and showing the ROI from their previous investments in drainage tile.
