Chesapeake Bay watershed 5 year  short-term nitrogen yields 2007 - 2011

Author: USGS

Date created: Jan 02, 2013

Average yields for total nitrogen (TN) were estimated for the last five years at 65 sites and classified into thirds as high, medium, and low. While the distribution was spatially variable, there were some general patterns in location. Generally, higher yields for TN are dominant in the middle of the watershed, areas that also coincide with large urban and agricultural land uses. The lowest yields are generally in the Virginia watersheds.
