Iowa Learning Farms December Webinar to Focus on Wetlands

AMES, Iowa — The Iowa Learning Farms Dec. 18 webinar will feature Bill Crumpton, Iowa State University professor in the department of Ecology, Evolution and Organismal Biology. Crumpton's research focuses on wetlands.

The webinar begins at 11:30 a.m. and is part of a free series, hosted by ILF, through Adobe Connect. The series is on the third Wednesday of each month. A computer with Internet access is all that is needed to participate. To connect to the webinar, go to at 11:30 a.m. on the morning of the webinar and log ini using the guest option.

Crumpton’s research focuses on wetlands and their function in agricultural landscapes. He is studying nutrient transformation and the effects of agricultural contaminants within wetlands. He developed a model for nitrate loss in wetlands that receive nonpoint source water on a watershed scale. This model is used to site and design alternative wetlands, serving as the foundation for the Iowa Conservation Reserve Enhancement Program. The program provides financial incentives for farmers to install wetlands in targeted locations to reduce nitrate loads from tile-drained fields.

Research has shown that CREP wetlands can remove 40-70 percent of nitrates and more than 90 percent of herbicides from cropland drainage waters. The CREP program is available in 37 Iowa counties in north central Iowa.

The ILF website contains links for archived webinars from all previous sessions at  The webinar archive also is available in a podcast through iTunes.

Iowa Learning Farms is a partnership of the Iowa Department of Agriculture and Land Stewardship, Iowa State University Extension and Outreach, Leopold Center for Sustainable Agriculture, Iowa Natural Resources Conservation Service and Iowa Department of Natural Resources (USEPA section 319); in cooperation with Conservation Districts of Iowa, the Iowa Farm Bureau and the Iowa Water Center.
