Also had another paper come from our collaboration with scientists at the Iowa Geological Survey Bureau - "Soil sedimentation and quality within the roadside ditches of an agricultural watershed" with authors Matthew T. Streeter, Keith E. Schilling, Martin St. Clair, and Zachary Demanett was published in Science of the Total Environment (https://doi.org/10.1016/j.scitotenv.2018.12.113).
Nice update - the Iowa Nutrient Center has been featuring the "roadside ditches" paper in releases to the press. The news release is here; it was also picked up in the High Plains Journal.
