The Iowa State Capitol Terrace lawn is getting covered with layers of fresh compost this week in an effort to improve soil quality and reduce storm water runoff.

The Iowa Department of Natural Resources (DNR) is leading the project in partnership with the Iowa Department of Administrative Services, and the U.S. Environmental Protection Agency, with technical assistance from the Iowa Department of Agriculture and Land Stewardship urban conservation program. Work crews will blow dark colored compost on the lawn west of the Capitol building. While the mixture of organic material and manure will be visible at first, it will mix in with top soil within a few weeks, according to a statement by the DNR.

“Soil quality restoration is something that people can do in their own backyards as well to improve the water quality in their neighborhood creek or other local water body. It also makes their yard look great, too,” said Steve Konrady of the DNR’s Watershed Improvement Program. He added, “Some communities in Iowa offer assistance to homeowners for this practice, and this Capitol Terrace project is a great opportunity to demonstrate the practice to Iowans, and to work to improve state lands and waters, and cleaner water downstream.”

Des Moines residents that live and work in the area need not worry about any foul odor. “Truly processed compost should be odorless — almost like a potting substance,” Konrady said to The Register.

Midwest researchers come together for research project

Roughly 30 students, professors, and researchers from six different institutions met in Muscatine this week to discuss a collaborative research effort to improve land, water, and air quality in the Midwest.

This Midwestern project is part of a nation-wide project known as the Critical Zone Observatory (CZO) an effort by the National Science Foundation to “[study] the zone where rock meets life.” The Midwestern project is called the CZO-IML (Intensely Managed Landscapes) and focuses on watersheds and lands in Illinois, Iowa, and Minnesota.

The Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS) in Muscatine hosted the IML-CZO conference which began Tuesday and ends today. This marked the second annual meeting for what will be a five year project.

“The first year was a lot of planning and field campaigns. The second year we’ve collected some data will be able to get that back to look at the results. We finally have some things to discuss, some real science,” said LACMRERS Director Doug Schnoebelen.

Schnoebelen, who also serves as a contributor for the IML-CZO project as well as a member of CGRER, said he hopes this research will be helpful not just for farmers and watershed managers but also for the general public.

“We’re hoping to look at an integrated approach and that’s what the Critical Zone is, being able to say something about water movement, soil conservation, transformation of carbon and energy in the environment. All of these things are really critical to the soil, the water, and the way we live.”

The conference brought together researchers from Indiana University, Northwestern University, Purdue University, University of Illinois, University of Iowa, and University of Tennessee. Schnoebelen said this emphasis on collaboration over competition has been key to the success of the project. He added that he is also grateful the CZO chose to support a Midwestern research project since much of the CZO’s other research takes place on the coasts.

“I think it was important when the national team came out and they realized how managed our landscape was and how important this research really was. It’s not just flyover country in the Midwest, it’s a critical part of our economy for food and energy.”

ISU: Crop cover yields water, soil quality results

Iowa State University has found a link between perennial crop covers and high soil and water quality.

Soil quality, water quality, and possibly even farm profits will all benefit by using a perennial cover crop on corn fields that allows for similar yields to traditional farming methods, according to Iowa State University research. Continue reading
