What's the difference?  In yield?  Nothing.  It's why we quit doing it.  If I'm not going to see more bushels (which is what I convert to dollars not pics at v5) then I'm not going to waste my time with it. 

In costs?  Plenty...it's more than a buck an acre here.

In Time?  Well, it isn't just 5 mins to load.  We did it for a decade and know exactly what it takes to nurse a planter from all my N needs and a popup or just a popup. 

If you want to put it on...it's fine with me.  It may be a huge money maker for you, it's a net loser for me.
