Title: ORNL FACE Nitrogen Concentrations (Leaves, Litter, Fine Roots, Wood)

Abstract

This report documents the file, Nconc.dat, which contains the nitrogen concentration data for leaves, litter, fine roots, and wood for 1998-2006. These data were collected for rings 1 and 2 which are exposed to elevated CO2 and rings 3-5 which have ambient CO2. The 2005 and 2006 nitrogen concentrations for fine roots will be included when they become available. The N concentration in leaves could not be measured in ring 5 in 2006; an estimated value based on N concentration in litter and an average resorption efficiency is 1.073%. Additional information describing this dataset can be found in Norby, R.J. and C.M. Iversen (2006). Nitrogen uptake, distribution, turnover, and efficiency of use in a CO2-enriched sweetgum forest. Ecology 87:5-14.
