The Iowa Learning Farms webinar will feature Bill Crumpton, Iowa State University professor in the department of Ecology, Evolution and Organismal Biology, whose research focuses on wetlands.
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 (CREP). 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 over 90 percent of herbicides from cropland drainage waters. The CREP program is available in 37 Iowa counties in north central Iowa.
The webinar is part of a series, hosted by ILF, held on the third Wednesday of each month. The webinars are held over the noon hour through Adobe Connect. All that is needed to participate is a computer with Internet access. The topics discussed will be beneficial for technical service providers, watershed project coordinators, Extension specialists and anyone else interested in the topic of the month.
