  abstract = {{I}n mine soil, quantification of soil organic carbon ({OC}) derived recently from biomass decomposition is complicated by the presence of fossil (geogenic) {C} derived from coal, oil shale, or similar material in the overburden. {T}he only reliable method for such measurement is 14{C} analysis (i.e. radiocarbon dating) using instrumentation such as accelerator mass spectrometry, which is too expensive for routine laboratory analysis. {W}e tested two previously used and two new methods for recent {C} quantification and compared them with 14{C} {AMS} radiocarbon dating as a reference using a set of soil samples (n = 14) from {S}okolov, {C}zech {R}epublic: (i) 13{C} isotope ratio composition, (ii) cross polarization magic angle spinning 13{C} nuclear magnetic resonance ({CPMAS} 13{C} {NMR}) spectroscopy, (iii) near infrared spectroscopy ({NIRS}) coupled with partial least squares regression and (iv) {R}ock-{E}val pyrolysis. {C}onventional methods for {OC} determination (dry combustion, wet dichromate oxidation, loss-on-ignition) were also compared to quantify any bias connected with their use. {A}ll the methods provided acceptable recent carbon estimates in the presence of mostly aliphatic fossil {C} from kerogen. {H}owever, the most accurate predictions were obtained with two approaches using {R}ock-{E}val pyrolysis parameters as predictors, namely (i) {S}2 curve components and (ii) oxygen index ({OI}). {T}he {S}2 curve approach is based on the lower thermal stability of recent vs. fossil organic matter. {T}he {OI} approach corresponded well with 13{C} {NMR} spectra, which showed that samples rich in recent {C} were richer in carboxyl {C} and {O}-alkyl {C}. {T}hese two methods showed the greatest potential as routine methods for recent {C} quantification.},
