Climate Scientist to Speak at Iowa Field Day

DES MOINES, Iowa - Torrential rains this year have already made 2010 the second-wettest summer in Iowa in 130 years of record keeping. The downpours have caused massive soil erosion and run-off, and made it next to impossible for many Iowa farmers to put in a crop or maintain it.

How to deal with massive rainfall will be part of a field day coming up September 11 at the Harlan-area farm of Ron and Maria Rosemann. Speaking at the event will be Eugene Tackle, director of the Climate Science Program at Iowa State University.

Rosemann has discovered one method to help absorb some of the rain.

"Cover crops can take up some of that moisture; anything that we can do to keep water where it's supposed to be, instead of running off into our rivers and streams and causing all these problems downstream."

Rosemann says his farm has been part of a study of water infiltration which determines how much water soil will hold. He says crop rotation helps the earth hold water too, but part of the run-off problem comes from soil that is compacted.

"That's especially with your big heavy equipment; your large planters and tractors and grain carts going across fields do cause compaction. That's another issue involving water infiltration."

The field day will include a tour of the Rosemann certified organic farm, along with their cow-calf and farrow-to-finish hog operation.

The field day will be Saturday, September 11 from 10:00 a.m. to 2:00 p.m. at the Ron and Maria Rosemann Farm, 1222 Ironwood Road, Harlan.
