I'll put our midwestern grassland prairie soils (or pampas soils in SA) up 
against the best of the forest soils.  I'll grow just as good a crop but 
won't have to pull stumps to do it ;<)
Furthermore I'll take burned out farm land and graze it for 10 years and 
get similar results to 100 years of reforestation, plus I get to eat 
beef.  Dogmatism is a barrier to progress, I'd advise folks not to get 
sucked in by nonsense like only forests making humates.
