WASHINGTON — A record high 81.5 million acres of soybeans will be planted this year while corn acres will be the lowest since 2010, according to U.S. Department of Agriculture’s prospective plantings estimate released March 31.

If realized, the soybean planted acres would be 6 percent higher than the 76.533 million last year. U.S. farmers planted 77.198 million acres of soybeans in 2012.

Despite the 4-percent decrease in corn planted area to 91.7 million acres, this still would be the fifth-largest corn acreage in the U.S. since 1944.

U.S. corn growers planted 95.365 million acres in 2013 and 97.155 million in 2012.

Compared with last year, planted acreage intentions for soybeans are up or unchanged across all states with the exception of declines in Missouri at 2 percent and Oklahoma at 1 percent.

Soybean acres in Illinois are projected to increase 1 percent from last year with 9.5 million acres, compared to 9.45 million in 2013 and 9.05 million two years ago.

Indiana matches the national trend with a 6-percent increase to 5.5 million acres of soybeans. Indiana had 5.2 million acres last year and 5.15 million in 2012.

Iowa soybean acreage is estimated at 9.6 million acres, up 3 percent from 9.3 million in 2013. The Hawkeye State had 9.35 million soybean acres two years ago.

Illinois corn planted acres is anticipated to drop 1 percent to 11.9 million acres after 12 million acres tallied in 2013. The state had 12.8 million corn acres in 2012.

The USDA projected Indiana’s corn planted acres at 5.8 million, down 3 percent from 6 million in 2013 and below 2012’s 6.25 million.

Iowa will increase corn planted acres by 3 percent from 13.6 million in 2013 to 14 million this year. Iowa had 14.2 million acres of corn in 2012.

The acreage estimates in this report are based primarily on surveys conducted during the first two weeks of March.
