Project Number: 8070-13000-012-29
Start Date: Aug 01, 2013
End Date: Feb 27, 2015
Watersheds in the Chesapeake, Heartland and Southeastern regions of the US will serve as the test bed for the P Index using monitoring data and model output. Each watershed will be subject to assessments at field and watershed scales by Soil and Water Assessment Tool (SWAT) and/or Agricultural Policy/Environmental eXtender (APEX) model and at field scale by the local P Index. ARS will coordinate modeling between Southern Extension Research Activity (SERA)-17 teams working to improve the P Index.
