Cover Crop Day to be held near Gilmore City

GILMORE CITY, Iowa – Iowa Learning Farms, the Iowa Nutrient Research Center and Iowa Corn will host a day on nutrient management, cover crops and wetlands near Gilmore City on Wednesday, September 8. The event, from 10:30 a.m. to 1 p.m., will be held at the Iowa State University Drainage Research and Demonstration Project, owned by the Pocahontas Soil and Water Conservation District. The event is free, open to the family and includes a free meal. This event will be organized in conjunction with the WHO Great Water Quality Show on Wednesday.

Cover crops continue to gain popularity in Iowa due to their many benefits, including increased soil organic matter, the potential for weed control, and reduced soil erosion. Along with field-edge practices such as bioreactors, wetlands, and saturated buffers, they are critical to reducing nitrate loss from farmland in Iowa.

Field day will feature Emily Waring, an agricultural and biosystems engineering graduate student at Iowa State University, discussing the growth of cover crop mixtures. Matt Helmers, professor and agricultural engineering specialist at Iowa State University Extension and Outreach, will share information on water quality findings from over 30 years at the Drainage Water Quality Research Center. Carl Pederson, agricultural engineering and biosystems specialist at Iowa State University, will discuss cover crop management and the impacts on cash crops. The field day will end at a nearby nitrate removal wetland with William Crumpton, professor of environmental science and wetland ecology expert at Iowa State.

Field day will be held at the Gilmore City research and demonstration site in Iowa. From Gilmore City, travel three kilometers west on Highway 3, then one kilometer north on 320th Ave. and finally half a mile west on 510th St.

The workshop is free and open to the public, but RSVP is desired for food planning. Contact Emily Waring at 402-350-0428 or email [email protected]
