Harvest Ready to Enter Full-Swing In Iowa

First frost hit Iowa this past weekend, but most crops were mature enough and weren’t affected

"The frost this past weekend covered much of the northern part of the state and really put many farmers on pace to begin full-fledge harvest this coming week. Let's hope the weather continues to cooperate and farmers can get the crop in," says Iowa Secretary of Agriculture Bill Northey.
Northey made his comments yesterday after the weekly Iowa weather and crop condition survey was released by the Iowa Ag Statistics Service. Results of the statewide survey were compiled September 16 and released September 17.
“There was definitely some frost in Iowa this past weekend—especially in northern Iowa,” says Elwynn Taylor, ISU Extension climatologist. Even as far south as Gladbrook, northeast of Marshalltown, a farmer reported his soybeans were bright green Friday afternoon and black leaves showed up on Sunday September 16. The frost that nipped the crops will advance the season.

Most crops were mature enough not be affected by the frost, but soybeans planted late in the season had leaves nipped. Corn silage and third alfalfa crop harvest is finishing up. Corn reels are being used to harvest downed corn. Harvest is expected to be in full swing this coming week. Insect pressure has lessened with the frost.
