DGS participates in study of subsurface phosphorus risk assessment

DGS staff member Scott Andres is a co-author on a paper “ASSESSING COASTAL PLAIN RISK INDICES FOR SUBSURFACE PHOSPHORUS LOSS" that was recently published in a special issue of the Journal of Environmental Quality. The lead author of the paper is Amy Shober of the UD College of Agriculture and Natural Resources. Co-authors include Anthony Buda (U.S. Dept. of Agriculture), Kathryn Turner and Thomas Sims (UD), Nicole Fiorellino (U. Maryland), and Joshua McGrath (U. Kentucky). Phosphorus (P) loss through the subsurface is a concern in Delaware and other states in the mid-Atlantic region where many agricultural fields drained by ditches or tiles are overloaded with P and downstream creeks, rivers, and bays are eutrophied from overloading with P and nitrogen.
