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.
