SIOUX FALLS, S.D. (AP) - The future of corn prices, conservation and global trends will be among the issues discussed at the South Dakota Corn Growers Association's annual meeting in Sioux Falls. It's Jan. 18 at the convention center. The federal government released a report Friday showing that South Dakota farmers produced a record 809 million bushels of corn last year. Corn prices are low because of a large harvest across the Midwest.
