“Corn will make up 68 percent of this year’s projected harvest of major U.S. grains and oilseeds this year, according to data the U.S. Department of Agriculture released Wednesday. That’s up from 47 percent in 1968. New markets and technology have made corn more profitable compared to other crops, which is why longtime farmers once devoted to competitive grains have switched to the nation’s number-one source for biofuels and cattle feed.” From Bloomberg: The Crop That Ate America.
