A new technology for cleansing nutrients from water leaving Iowa’s tile-drained fields began with two Iowa State University researchers brainstorming after a professional meeting. Their “back of the napkin” discussion in 2010 led to development of saturated riparian buffers, a new conservation practice that is rapidly gaining interest in Iowa and far beyond.
Fifteen years of wetlands research by Iowa State University – a study thought to be the largest and longest running project of its kind in the country – clarifies their performance as highly beneficial systems for reducing nitrogen pollution.
“Profiles in the Wonders of Iowa’s Wetlands” will feature 12 in-depth educational videos highlighting the diversity and benefits of wetland ecosystems throughout the state. The videos are being developed by Iowa State University Extension and Outreach and the Iowa Nutrient Research Center. A webinar on Tuesday, May 25, at 7-8 p.m., kicks off the series during American Wetlands Month.
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.
Cover crops are known to protect soil and water quality, but they also can offer valuable livestock feed, according to Iowa State University research.
AMES, Iowa – This spring, the Iowa Nutrient Research Center’s water quality research seminar series will “Focus on Phosphorus,” beginning Wednesday, Jan. 26, 2022. The presentations will take place the fourth Wednesday of each month, from 3:10-4:00 p.m., through April 27.
A new Researcher Directory being launched this week highlights Iowa scientists engaged in nutrient reduction research. The online search tool is hosted by the Iowa Nutrient Research Center, at https://www.cals.iastate.edu/inrc/researcher-directory.
AMES, Iowa — A research project by Iowa State University soil scientists provides new insight into the complex picture of phosphorus loss from farmland and evidence proving phosphorus runoff is often underestimated.
AMES, Iowa- The Iowa Nutrient Research Center is accepting new proposals for research projects designed to reduce nitrate and phosphorus in Iowa’s water.
