DES MOINES, Iowa (AP) — U.S. Sen. Chuck Grassley has asked the federal government to declare 27 additional Iowa counties across the state as agriculture disaster areas following several summer storms.

The Iowa Republican sent a letter Tuesday to U.S. Department of Agriculture Secretary Tom Vilsack seeking the designation.

Grassley says farmers across the state have faced "about every kind of challenge that summer weather can bring."

If granted, farmers in the counties and in the counties adjacent to them would be eligible for FSA emergency loans, the Livestock Indemnity Program and the Supplemental Revenue Assistance Payments Program.
