and the book there. For ethanol, you can reach highest yields using cattails that filter humanure in every county in the country. In the arid regions, you can harvest mesquite pods, buffalo gourd, prickly pears, pimelon and other such plants without any inputs needed. Kelp is a good crop if one is careful. A lot of work is being done on sorghum which can grow as far north as Iowa. Beets, fodder and sugar, are good crops, as are Jerusalem artichokes.

Miscanthus may be more beneficial than switchgrass and a variety of grasses planted even better- even grasses should not be vast monocrops.

Thanks again.
