Corn futures in Chicago hit a three-year high as widespread flooding across the US Corn Belt delayed planting. USDA data showed 58% of corn planted versus 90% a year earlier, and soybeans at 30% planted against a five-year average above 70%.
Reuters estimates about 99 million acres of corn and soybeans remain unplanted.
Flooding threatens a large share of the US crop and may cut acreage and yields, pushing grain prices higher as planting windows close.
