Plant Sci. 10:664. doi: 10.3389/fpls.2019.00664Metadata:Mass- and area-based concentrations of green leaves from each of the six plots at EucFACE across 6 years (2012-2018, including different campaigns per year). Ambient plots are represented by rings 2, 3 and 6 while elevated plots are rings 1, 4 and 5. Similar set up and description for senesced leaves and wood, although the values here are just mass-based expressed in percentage (indicated by Perc.N or Perc.P for each nutrient - need to multiply by 10 to get mg g-1). Following descriptors are being used: Campaign: time of measurement Date: data of measurement Year Ring: treatment plot (see above) CO2.treat: CO2 treatment (see above) Tree: tree number Age : leaf age class LeafAge : leaf age on a continuous basis as days since leaf flushing Variables: LMA: leaf mass per area ratio in g m-2 N and P: are nitrogen (N) and phosphorus (P) concentrations respectively with m and a indicating mass- and area bases (for example Na or Nm). The ratios of N to P are expressed at NP and similar.
