Wet weather slowed progress, but Iowa farmers were able to get some planting done last week.

The latest crop report Monday from the U.S.D.A. shows 40 percent of the corn acres have been planted. That’s up from 13 percent reported last week.

The planting is already six days ahead of last year and 11 days ahead of the 5-year average. The report says farmers in the north central, central, and southeast portions of Iowa have made the most progress — with half their corn crop now in the ground.

The U.S.D.A. crop report did not mention any soybean planting, but Iowa Ag Secretary Bill Northey says he’s heard some reports of farmers already starting to plant their beans.
