More than 1,500 farmers now plant 7 million acres of organic crops a year in Argentina, up from 220 farmers and 13,000 acres in 1995. For the most part, people in Argentina haven’t developed a taste for the stuff — 90 percent of the country’s organic crops are exported, mostly to the U.S. and Europe. The leading organic crops include soybeans, corn, fruits, rice, sugar, and tobacco. Jose Nanni, who converted his family’s 100-year-old vineyard to organic production a few years ago, said, “We don’t need to use any type of chemicals because of the characteristics of the area where we grow our grapes.”
