The corn is tall and still a lustrous green through much of Minnesota. But it's not going to stay that way for long without a good soaking rain -- pronto.
Already, Minnesota corn farmers are seeing wilting leaves and other signs of heat stress, though nothing like the drought that has stunted crops through much of the Corn Belt.
"Most states would trade places with us in a heartbeat," said Michael Swanson, an agricultural economist at Wells Fargo. "We've got it good right now compared to most of them."
Indeed, 77 percent of Minnesota's corn crop was in good to excellent condition for the week ending Sunday, the best of any state, according to Department of Agriculture data released Monday.
"The potential is there for a real good crop," said Chad Willis, who farms corn and soybeans east of Willmar. "But that dwindles every day that it doesn't rain."
The National Weather Service's forecast is not what farmers like Willis want to see: no appreciable rain through at least Friday, and temperatures climbing as the week goes on -- a potential double whammy.
Lured by high corn prices, farmers this spring sowed what's believed to be the biggest U.S. corn crop since 1937. But a heat wave across the Midwest has parched Illinois, Indiana, eastern Iowa and other key corn-growing areas. When July started, U.S. corn crops were in their worst shape since 1988.
"The stage was set for one of the biggest crops in the U.S. ever, and now it is pretty apparent that is not going to happen," said Douglas Tiffany, an assistant extension professor and renewable energy economist at the University of Minnesota.
