Farmers can earn money for not harvesting some corn.
The Minnesota Department of Transportation pays farmers who leave about eight rows of corn stalks standing through the winter.
MnDOT pays more than a farmer would get by selling the corn.
The standing corn on the north and west sides of highways and interstates serves as a snow fence to help improve winter driving conditions and reduce snow plowing.
MnDOT reports the corn stalks can capture nearly 12,000 tons of snow in a quarter of a mile.
