Brazil Grows Two Corn Crops?

Who knew that?  Saw a reference to it, probably from John Phipps or Chris Clayton's feed.  Here's the brief description:

Brazil’s second corn crop, or safrinha, has gained attention in world markets because this year’s dry growing season likely hurt yields. Safrinha corn accounts for about 65% of the country’s corn production.

It's planted in January to March after early-crop soybeans are harvested.  

The fact it's doable on a massive scale suggests to me Brazil has an advantage over US farmers, who are limited in their doublecropping to soybeans after wheat, mostly.   Of course, with global warming we may be able to change that in the future.  We still have an infrastructure advantage over Brazil, if I understand correctly--we've the transportation--rail and barge--to move crops to export ports easier than they currently do.  But that too will change.
