BISMARCK, N.D. — The U.S. Department of Agriculture plans to resurvey hundreds of small grains farmers in eight states who still had crops in the field when they were asked a month ago about their yearly production.

The information could result in a revision of the official government estimates of wheat, barley and oat production. But it shouldn’t affect food prices.

USDA this month plans to resurvey affected farmers in both Dakotas, Minnesota, Montana, Utah, Idaho, Colorado and Wyoming. Any changes to production estimates will be published Nov. 10.

Weather-delayed harvests have prompted USDA to do follow-up surveys before, but an agency official said it’s never happened in so many states.

USDA data show the surveys typically result in only minor adjustments to official crop estimates and often don’t result in any changes.
