Nutrient Loss Database for Agricultural Fields and Forests in the US
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 land uses.
The resulting publicly available data base provides:
1) measured nutrient load and concentration data in runoff and drainage 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,and3) a platform allowing user input of additional project-specific data.
