Backdrop: Example of beef feedlot runoff containing manure solids. Systems are designed to remove most of these solids prior to application to cropland. Inset: Example of feedlot pen surface with excreted manure solids containing unmetabolized and metabolized antibiotics. Precipitation carries these solids to holding ponds for partial treatment before being applied to cropland. Photos by Dr. Bryan Woodbury.
