At the CBOT, December corn settled down 8-1/2 cents at $3.37 per bushel. November soybeans ended down 8-3/4 cents at $9.45-1/2 a bushel and December wheat fell 10-1/2 cents at $3.96-3/4 a bushel.
Corn posted the biggest percentage declines on chart-based selling. The USDA lowered its estimate of the U.S. 2016 corn yield to 173.4 bushels per acre, from 174.4 in September, but still the highest on record, if realized.
