Lucas,

Actually I am just a bit north of you around the Husker Harvest Days area with corn being excellent to fair depending on….?  On the subject of flow rates just when we think we are calibrated we go to a different variety and the scale shows the previous calibration is now off.  Just the other day over lunch I had a friendly debate with a Pioneer marketing rep about them using yield monitor data to add to the replications of variety testing vs. using a scale to do that.  He did add that they keep those records separate but let’s just say we did not agree on the concept of even using a yield monitor to compare hybrid selections.  Having said all that yield monitors are still very good in the relative (i.e. pivot tracks) and so as you said yield maps should be THE foundation of PA.

I personally prefer more infinite gradual stepping and control with higher resolution surfaces vs. say a bang bang change with a few values that most likely are pretty far apart from each other.  I think this is referred to as “management zones” in the industry.  As Marv stated the controllers tend to smooth things out but that would tend to overshoot and undershoot application going into and out of those areas.  It may just be a matter of syntax but I think we should keep the resolution high and let the application processes catch up.
