(Table 5) Soil fractions calculated based on POC : PN ratios and δ¹³C values and associated estimated 14C concentrations of the soil-derived POM fraction

Soil fractions are given with standard deviation (1 Sigma). D14C values are given with lower quantile (q16) and upper quantile (q84), representing the 68% confidence interval (1 Sigma for normal distributions). D14C values lower than -1000 per mil were marked as "fossil".
