Breaking News-RTRS-US corn seeding near deadline, acres may go to soy

CHICAGO, June 5 (Reuters) - The window to plant corn is closing rapidly in the heart of the U.S. Corn Belt as two key states struggle to finish, putting at least a million acres of expected corn output at risk of being switched to soybeans.
Illinois and Indiana, which produce a quarter of the American corn crop, had some 3.4 million acres of corn yet to plant this week at a time when all seedings are usually complete. Southern areas of the states were furthest behind.
Depending on how small the crop gets, analysts now say U.S. corn stocks may be the lowest since 2003 by next year.
