The USDA’s highly-anticipated Acreage report, released Monday, showed corn planting at 91.6 million acres, down 4 percent from 2013.

“This represents the lowest planted acreage in the United States since 2010; however, this is the fifth largest corn acreage in the United States since 1944,” the report said.

Unseasonably cold temperatures and heavy rains impact many acres across the Corn Belt, leaving some experts to question the accuracy of the Acreage report even before it was released. Prior to the Acreage report’s release, forecasters anticipated corn acreage at 91.7 million acres — 34,000 acres more than reported in March’s Prospective Plantings report.

Instead, the Acreage report showed a slip dip from the USDA’s March report.

The actual figure may be considerably lower. A survey of 2,800 farmers in 11 states by broker Roach Ag Marketing found that most expect the corn planting to drop below 90 million.

The survey finding reflects that "unseasonably cold temperatures, and heavy rainfall in states were expected to increase corn acres the most,” Roach Ag president Brian Roach told AgriMoney.

Many of the farmers surveyed noted that five states – Minnesota, Nebraska, North Dakota, South Dakota, and Wisconsin – made up 80 percent of the acreage losses reported this year. Producers in these states reported “extended plantings delays” due to the weather.

Despite the delays, Roach did not expect the USDA’s report the “to reduce their corn plantings nearly as much as our survey reported.”
