The acres of corn harvest is expected to rise from the current 71 million to 80-85 million over the next five years, MacDonald said. Yields are projected to rise from about 150 bushels per acre to almost 180 bushels per acre in the next 10 years.
"We're not sure how big the ethanol industry is going to get, but if every plant being proposed as of now gets built, the Renewable Fuels Association says we'll be producing 12.5 billion gallons of ethanol a year from starch," he said.
In estimating feed availability for livestock, MacDonald assumed as much as 15 billion gallons of ethanol being produced annually. At that rate, 35.5 percent of all corn would be needed for ethanol. This would bring the amount of corn available for feed down from the current 60 percent to 33.5 percent, assuming the other categories remain steady.
