There is little (if any) yield or economic advantage to either full-width tillage or strip-till, as has been shown in a great many studies. Of course, some of the researchers still think that something is wrong with their studies, that surely there must be a positive yield response to tillage. Others are more willing to rethink their assumptions based on where the evidence leads.

And here's a producer who finds planting corn on corn (including into 150- to 200-bu/a stalks) no problem (and he's on 20-inch rows!):

Also, Dwayne Beck at Dakota Lakes Research Farm has both continuous corn (15 yrs in corn) and stacked corn (2 yrs of corn consecutively within a longer diversified rotation) under irrigation. There are no tillage comparisons (it's all no-till) but yields are very good. Those are also on 20-inch rows.
Again, this won't persuade any of you who are staunch in your view of tillage as somehow necessary or benefical. I put this forward for those of you who are open-minded enough to consider this possibility. | |
