identifier: identifier of the study plot
core_id: identifier of the core within the study plot
month_name: Month and year when root sample was taken 
sampling_depth: Root core depth [cm]	
layer: "USL" for 0-10 cm sampling depth, "DSL" for sampling depths 10-40 cm

dw_l: Dry weight of living fine roots [g]	
dw_n: Dry weight of dead fine roots [g]	
dw_fa: Dry weight of fine approach [g]
dw_n_total: Dry weight of dead fine roots (dw_n) plus dry weight of dead fine roots measured or determined by linear regression for finest dead root fractions (fine approach)	
fine_approach: was the sample analysed by the fine approach [Y = yes; N = no]; if no, dw_fa was determined by linear regression

frb: Fine root biomass; Dry weight living roots divided by area of root corer [g/m^2]	
frn: Fine root necromass; Dry weight dead roots divided by area of root corer [g/m^2]			
frn_total: Dry weight of dead fine roots (dw_n) plus dry weight of dead fine roots determined by linear regression for finest dead root fractions divided by area of root corer [g/m^2]
fbn: Fine root biomass to necromass ratio; frb divided by frn_total
