Already beset with problems caused by trade wars and low commodity prices, many U.S. farmers are facing yet another challenge: wet, muddy fields keeping them from reaping their fall harvest.

In Wisconsin, there were only two days suitable for field work in the week ending October 7, according to a crops report from the U.S. Department of Agriculture office in Madison.

“Those that tried to harvest corn, corn silage, or soybeans were very creative or were getting stuck,” a crops observer from Adams and Juneau counties said in the report.

“You need a boat to get into some fields,” quipped Kevin Jarek, a University of Wisconsin Extension agent in Outagamie County.

Still, in many places, the crops look healthy despite too much rain.

Forty-two percent of the corn in the state was rated "good,” while 29 percent was "excellent," the crops report, released Tuesday, said.

"Corn yields are very good as harvest progresses slowly on the high and dry land," a crops observer from Green County said.  

Likewise, 44 percent of the soybeans were rated good and 27 percent excellent.
