AMES, Iowa — Iowa Learning Farms will host a webinar on Wednesday, June 24 at noon about the potential that targeted wetland restorations have to reduce agricultural nutrient loads.
Over the past 15 years, over 90 wetlands have been restored through the Iowa Conservation Reserve Enhancement Program with the explicit goal of intercepting and reducing nonpoint source nitrate loads. William Crumpton, university professor in ecology, evolution and organismal biology at Iowa State University, will summarize results from 15 years of work on Iowa CREP wetlands, including nutrient removal, GHG emissions, and hydrology. The research presented in this webinar is one of the largest and longest running projects of its kind and helps to clarify the potential benefits and limitations of targeted wetland restorations.
“The Iowa Nutrient Reduction Strategy includes a wide range of in-field and off-field practices, but will likely require restoring thousands of wetlands targeted to intercept and reduce nitrate loads from cultivated cropland,” said Crumpton, who studies wetland processes and functions, including the dynamics of energy flow and nutrient transformation in wetlands, the fate and effects of agricultural contaminants in wetlands, and the role of restored and constructed wetlands in watershed hydrology and water quality.
“I hope participants will better understand the effects of targeted wetland restorations on water quality and hydrology and thus appreciate the potential benefits and limitations of this practice in Iowa’s agricultural landscapes,” Crumpton said.
