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 bemeasured 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.

ORNL FACE Fine Root Data

Dataset Ledford, J. ; Norby, R.J. ; Tharp, M.L.

This report documents 3 data files with names of root_production.dat,root_mortality.dat, and root_crop.dat. These data were recorded biweekly during the growing season on five FACE plots from 1998 through 2006. Beginning in 2004, data also were recorded monthly during the winter.The calculation of root-length production, mortality, and standingcrop is described in Hendrick, R.L. and K.S.Pregitzer (1993) The dynamics of fine root length, biomass, and nitrogen content in two northern hardwood ecosystems. Can. J. For. Res. 23:2507-2520. Methods for collecting these data are documented in Norby, R.J., J. Ledford, C.D. Reilly, N.E. Miller, and E.G.

ORNL FACE CO2 Concentration Data

Dataset Riggs, J.S ; Tharp, M.L. ; Norby, R.J.

CO2 concentration data are available for 1999-2006. There is an hourly file for each year which contains elevated and ambient CO2 concentrations. The 2007 file will be updated as data become available. These data files include FACE site measurements of CO2 concentrationsfor rings 1, 2, 4, and 5. Rings 1 and 2 are elevated CO2 concentrations, and rings 4 and 5 are ambient CO2 concentrations. CO2 is sampled continuously from the top of the canopy at the center of eachring and is measured with a LiCor 6252 infrared gas analyzer located in an instrument shed next to each ring.

ORNL FACE Tree Height, with data on height of a subset of trees measured every year, 1997-2009. Free-Air CO2 Enrichment (FACE) Experiment Synthesis Activities.

Dataset Norby, Richard

Height of 20 sweetgum trees in three rows of each of the plots in the Oak Ridge National Laboratory (ORNL) free-air CO2 enrichment (FACE) experiment was measured each year of the experiment (1997-2009). The trees were exposed to ambient or elevated CO2. Tree height data contribute to the overall project objectives to determine the integrated response of a deciduous forest to elevated CO2. Average tree height per plot was used in allometric equations to calculate tree dry mass each year and to test whether there were effects of elevated CO2 on canopy development. Height was derived from trigonometric calculation frommore »« less

Castanha et al. 2018: Hopland Lysimeter 13C-Labeled Root Litter Decomposition Study.

Dataset Castanha, Cristina ; Zhu, Biao ; Hicks Pries, Caitlin ; ...

The breakdown and decomposition of plant inputs are critical for nutrient cycling, soil development, and climate-ecosystem feedbacks, but uncertainties persist in how the rates and products of litter decomposition are affected by soil temperature, rhizosphere, and depth of input. To elucidate these questions we measured the effects of soil warming (+ 4 °C), rhizosphere, and depth of litter placement on the decomposition of Avena fatua (wild oat grass) root litter in a Mediterranean grassland ecosystem. Field lysimeters were subjected to three environmental treatments (heating, control, and plant removal) and three 13C-labeled root litter addition treatments (to A horizon, to Bmore »« less
