The spring planting survey shows farmers intend to plant over 97-million acres of corn this year.
USDA officials say this is the most since 1936. Record corn acreage is expected in Minnesota, Arizona, Idaho, Nevada, North Dakota and Oregon.
Corn remains profitable, as prices are strong after last years drought left the grain in short supply.
The report says farmers plan to plant just over 77.1 million acres in soybeans, down slightly from last year’s 77.2 million acres but still the fourth-highest soybean planting on record.
