A new trailer named “Marsh Madness” combines sight, sound and science to engage Iowa audiences about the values of the state’s wetland ecosystems. The artfully designed trailer features scenes of wetlands and their plant and animal communities and recorded sounds of wetland fauna. Adding to the immersive educational experience are three-dimensional interactive models demonstraing the unique landscape placement and hydrology of three wetland types typical in the state. The trailer was developed by Iowa Learning Farms team and the Iowa Nutrient Research Center.

The Iowa Nutrient Research Center at Iowa State University announces funding for 11 new water quality and nutrient management projects for 2020-2021.

“This round of projects represents over $1.3 million for water quality research,” said Matt Helmers, Iowa Nutrient Research Center director and professor of agricultural and biosystems engineering at Iowa State. “We are pleased that the projects reflect a number of the research priorities developed last year with a broad range of stakeholders, including farmers. These include supporting research on new nutrient-reduction technologies or cropping systems, developing better understanding of in-stream processes and examining potential unintended consequences of conservation practices.”
