  abstract = {{O}rganic matter ({OM}) is a key component of soils but information on its chemistry and behavior in soils is still incomplete. {N}umerous methods are commonly used to characterize and monitor {OM} dynamics, but only a few include the qualities required to become routine techniques i.e. simple, rapid, accurate and at low cost. {R}ock-{E}val pyrolysis ({RE} pyrolysis) is a good candidate, as it provides an overview of {OM} properties by monitoring four components related to the main major classes of organic constituents (from {A}1 for the labile biological constituents to {A}4 for the mature refractory fraction). {H}owever, a question is still pending: do these four major classes used in the literature reflect a pertinent compositional chemical counterpart? {C}-13 {N}uclear {M}agnetic {R}esonance {S}pectroscopy in the solid state ({C}-13 {CPMAS} {NMR}) has been used to answer this question by collecting information on structural and conformational characteristics of {OM}. {M}oreover, in order to avoid the blurring effect of pedogenesis on {OM} dynamics, a "less complex {OM}" source, i.e. compost samples, has been used. {R}esults showed significant and high determination coefficients between classes, indices (of transformation of plant biopolymers, humificationa{E}uro broken vertical bar) from {RE} pyrolysis, and the main classes of {OM} characterized by {C}-13 {NMR}, e.g. {A}1 & {A}2 with labile/easily degradable components (alkyl {C} et {O}-alkyl {C}), {A}3 & {A}4 with humified {OM} (with aromatic {C} and phenolic {C}). {T}he {R} index (contribution of bio-macromolecules) is correlated with phenolic and aromatic {C}, whereas the {I} index (related to immature {OM}) refers to labile--easily degradable components (alkyl {C} et {O}-alkyl {C}). {T}he results confirm the pertinence of {RE} pyrolysis to monitor {OM} dynamics.},
