text:  A dismal start to the week in the ag markets. This is Michigan Ag Today's Monday Closing Farm Market Report. And it was a sell-off everywhere today. Nearly a nickel lower in corn, getting pulled down by very weak soybeans and wheat futures. December corn 471.5, down 4.75. November soybeans 23.5, down at 13.16.75. And December wheat 591.25, a loss of 13 cents.
