Predicting Sorption, Mobility, Accumulation, and Degradation Potential of Antibiotics in Iowa’s Soil/Water Environment

September 28, 2020 / ibassis / / No Comments
In this project we propose to evaluate three common farm-animal antibiotics, chlortetracycline (Aureomycin), oxytetracycline (Terramycin) and erythromycin (a macrolide) with respect to their fate in Iowa’s soil/water environment. The expected

Effects of Grazing Management on Sediment and Phosphorus Losses from Pastures

September 28, 2020 / ibassis / / No Comments
Sediment and phosphorus loading of streams are major impairments of surface water sources in Iowa. While production of perennial forages may limit sediment and phosphorus losses in precipitation run-off, sediment
