Dr. Jenkins’ focus at the National Sedimentation Laboratory’s Water Quality and Ecology Research Unit is on charactering the effects of agricultural management practices on soil, sediment, and water archaeal, bacterial, and fungal communities with emphasis on nitrifying and denitrifying communities.
