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.
