Um, am I missing something here or is 160 not more than 50,...pounds of
nitrogen per acre that is?

I'm at an ag conference in Guelph, Ontario and just learned about
http://www.reap-canada.com

They harvest prairie biomass in early spring. Dried plants, pelletized and
burned without the ethanol step. 10:1 ERoEI compared to ethanol's 1:1, and
the prairie stays intact. 50lbs/acre of nitrogen added instead of corn's
160, and as they improve the mix of N-fixers that will improve further.
Convert all those cornfields back to prairie!
