INTRODUCTION
The primary objective of this effort was to compile measured annual nitrogen
(N) and phosphorus (P)load and concentration data representing field-scale
transport from agricultural and forest (new September 2009)land uses.
The resulting publicly available data base provides:
1) measured nutrient load and concentration data and corresponding watershed
characteristics from numerous field-scale studies,
2) readily accessible, easily queried information to support water quality
management, modeling, and future research design,and
3) a platform allowing user input of additional project-specific data.
