Run 5 Whys on a Bad Nitrogen Zone
Use 5 Whys to diagnose why a nitrogen management zone underperformed.
A high-rate nitrogen zone yielded 18 bushels below the field average, and the grower questions whether variable rate is worth continuing. 5 Whys: move from symptom to controllable cause, checking evidence at each step. The common trap is stopping at the first explanation that confirms a bias: the model failed, the operator missed it, the weather ruined it, or the grower should not have tried variable rate. Each may be possible, but none is proven by the symptom alone. Why 1 Why did the high-rate zone underperform? Because the extra nitrogen did not produce the expected yield response. This is…
