Iowa State University Advances Saturated Riparian Buffers as a Promising Water-quality Practice for Crop Fields

By College of Agriculture and Life Sciences

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 back in 2010. Their conversation led to development of saturated riparian buffers, a new conservation practice that is rapidly gaining interest in Iowa and far beyond.

Engineers develop ‘bury-and-forget’ sensors, data networks for better soil, water quality

By Mike Krapfl, Iowa State University News Service

Iowa State’s Jonathan Claussen, an assistant professor of mechanical engineering, is leading a team of engineers developing a system of low-cost, “bury-and-forget” soil sensors connected to a remote, wireless, data-collection network. Data collected by the system will help the engineers build better models of the interactions of fertilizer, soil and crops. Those models could help…

Rare-earth magnet recycling tech wins innovation award

By Laura Millsaps, Ames Laboratory Communications

An acid-free dissolution rare-earth magnet recycling process has earned a 2018 Notable Technology Development Award from the Federal Laboratories Consortium (FLC). Researchers at the Critical Materials Institute (CMI) and Ames Laboratory invented a magnet recycling process in which magnets are dissolved in water-based solutions, recovering more than 99 percent purity rare earth elements. Cobalt is…

Iowa State researchers find ozone pollution in U.S. national parks is nearly the same as in large cities

By The Conversation

Research by Iowa State University assistant professors in economics, David Keiser and Gabriel Lade, and Ivan Rudik, assistant professor of applied economics at Cornell University, Ithaca, New York, reveals that while cities once had more “bad air days” with unhealthy ozone levels than national parks, today parks and metro areas have virtually the same number…

Floating islands project studies water quality, pollinator plants

By Chelsea Davis, Iowa State University News Service

The sustainable environments interdisciplinary graduate program’s floating islands research project is back on Iowa State University’s Lake LaVerne for the first summer since 2015. While the project still measures nutrient uptake from the water, this year’s research adds a new twist. Pollinator plants are being used to determine if floating islands could have a twofold…
