Josh Turner drives a grain wagon to help his dad and uncle harvest one hundred acres of Illinois corn.

 "We had the corn planted once, we had to replant the corn. There's too much water because we didn't get the roots like we should and a few different things that contributed to it. It's just not as good as we'd like", says Turner.

Those low yields are frustrating farmers from mid- Illinois to southern Iowa.

"Crop insurance helps a lot. The revenue, the protection, that makes a big difference. You're not shouldering the whole loss on your own", says Nate Larson, Mediapolis farmer.

While April rains soaked fields and sat on top of growing stalks, rows of corn planted on tiers or sloping land surprisingly fared better.

Bob Dodds from the Iowa State University Cooperative Extension office says, "It has been interesting this year because of the excess moisture, anytime we have some slope on the fields, the yeilds go up, but on good flat soil that we're so used to those 200 bushel corn yields those are the fields that are really struggling this year because we just didn't have a place for that water to go".

Farmers in Iowa have battled wet spring weather for three years straight now but they say this year was the worst.

This fall harvest looks like it will stick to its own season.

"Hopefully the first of November we're done, last year was the 7th of December, hope that's not the case, we'll do our best, " says Turner.
