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 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.
