Narrow Row Corn

Is narrow row corn the wave of the future.  The reasoning behind narrow row corn is that we need to find a way to put more corn plants in an acre in order to push yields to higher levels needed to provide food, feed, and fuel to a growing population.  Many think that this cannot be done with corn in the "standard" 30 inch rows.  We have a number of customers who have experimented with some sort of narrower row system.  15 inch rows, 20 inch rows, and twin rows have all been used.  No particular advantage or disadvantage has come to light, but the idea cannot be easily dismissed.  Greg Sauder and Marion Calmer are both advocates of narrow row technology.  No-Till Farmer recently published and interesting article on narrow rows.
