Your comments are what I've seen over years of doing on-farm trials although it was more of an observation rather than a full trial to study this issue. It always appeared the response to N curve flattened at about the same amount of applied N regardless if the response ended at 150 bpa corn or 200 bpa corn.
I continue to be interested in how people build these recs. As you variable rated N for 15 years prior can you explain what you based the rate changes on?
