  abstract = {{C}hanges in the carbon ({C}) and nitrogen ({N}) compartments that result from the addition of organic material ({OM}) to the soil are predicted by the transformation of added {OM} ({TAO}) model with three parameters: very labile ({P}-{L}) and stable ({P}-{S}) fractions of the {OM} and the rate of remineralization (k(remin)) of nitrogen immobilized by microorganisms. {W}e propose relations between {P}-{L}, {P}-{S}, k(remin) and various chemical groups in the {OM} identified by their {C}-13 nuclear magnetic resonance ({NMR}) spectra. {T}he aromatic content increased the predicted {P}-{S} in accordance with published results. {T}he {O}-aromatic content also increased {P}-{S}, but much less so than the aromatic content. {T}he carboxyl content decreased {P}-{S} and increased {P}-{L} as in the {TAO} model based on infrared spectrometry. {T}he carbonyl content decreased {P}-{L}, whereas di-{O}-alkyl increased {P}-{L}. {T}he chemical composition of the population of decomposer organisms did not appear to be homeostatic, but was related rather to the composition of the substrate: k(remin) was positively correlated with the carboxyl and di-{O}-alkyl content and negatively correlated with the alkyl content. {S}olid state {C}-13 {NMR} spectroscopy gave better predictions of the transformations that resulted from adding {OM} than biochemical fractionation and near infrared reflectance spectrometry ({NIRS}). {I}t is fast and non-destructive and provides new insights into the processes that control decomposition for research into waste recycling, agro-ecology and climate change. {H}ighlights{L}inking decomposition of organic materials in soil to {NMR} measurements. {F}irst mathematical model of decomposition based on {NMR} spectra. {S}tability of the {OM} depends on the chemical groups and the inorganic {N} supply. {NMR} is a promising tool for monitoring ecosystem changes and soil-air exchanges.},
