The drought and a soaring U.S. dollar soured business conditions across much of middle America, according to a closely watched report issued Wednesday by Creighton University.
Supply managers surveyed across nine states reported that business conditions fell below an index of 50 for the first time since 2009. Any index above 50 signals growth. But any index below 50 signals economic contraction.
The Mid-America index fell to 48.7 percent in July from 57.2 in June.
Food processing plants and ethanol producers were especially affected by drought. In addition, new export orders across most industries fell to their lowest level since August 2009, while business confidence saw the biggest one-month drop since 1994.
The Creighton University report measures economic conditions in Minnesota, Iowa, Missouri, Oklahoma, Arkansas, Kansas, Nebraska and North and South Dakota.
In Minnesota, the Central MN Ethanol plant in Little Falls stopped production two weeks ago because of poor margins on ethanol and laid off 25 workers, Dana Persson, CEO and general manager, said Wednesday.
"It is due to the current crush margins -- they are particularly weak," Persson said, referring to the industry measure of the cost of producing ethanol. "Corn is in short supply."
The Little Falls plant, built in 1999, is among the smallest of the state's 21 ethanol plants, and the first in the state to shut down, though others have closed in Illinois and Nebraska.
