"The price of America's most important crop has just doubled, and farmers have ethanol to thank for the jackpot, reports Fortune's Jon Birger. But are they now sitting on a 'dot-corn' bubble?" "Put a little differently, the farmer who was making $27,000 raising 1,000 acres of corn in 2004 is in a position to earn $270,000 from 2007's crop." "Looming over all this is a huge catch-22: $4 corn is a result of the 31 new ethanol plants built since 2005, but investors won't keep bankrolling new plants if $4 corn keeps eating up their profits. That's why Credit Suisse's Ho thinks a corn correction is inevitable." http://money.cnn.com/2007/03/29/magazines/...rce=yahoo_quote
