Iowa State Research Aims to Improve Next Generation of Bioreactors

January 24, 2019

On a cold day last fall, Iowa State University scientist Michelle Soupir and her team of graduate students shoveled out the woodchip-and-mud entrails of nine concrete-lined water-quality cells at the Agricultural Engineering and Agronomy Research Farm near Ames. They packed samples from the cells — mini-bioreactors — into plastic bags and labeled them to take back to the lab, where they would measure bacterial activity and the rate of woodchip decomposition.

Multi-purpose Oxbows Make the Grade for Nutrient Reduction

November 14, 2019

New research shows that “multi-purpose oxbows” can effectively reduce nitrate-nitrogen, earning them a spot in the Iowa Nutrient Research Strategy’s menu of conservation options. Keith Schilling, State Geologist and Director of the Iowa Geological Survey, is lead investigator for Iowa Nutrient Research Center- sponsored research to better understand the benefits of oxbow restoration for water quality. Partners in the research include the Iowa Soybean Association, The Nature Conservancy and the U.S. Geological Survey's Iowa Cooperative Fish and Wildlife Research Unit at Iowa State.
