Northern Nebraska | I know my post said field as in singular but it definitely is multiple fields that require potassium even if it's only a tissue test that says it is low.
As for Nebraska having generally high soil test levels of potassium, we decidedly do. However we also see visual symptoms of potassium deficiency. Actually pioneer is doing a machine learning study on tissue test levels and yield and they can't figure out why Nebraska consistently sees response to added potassium. Even with soil levels that most areas could only dream of.
