- Inelastic neutron scattering (INS) was applied to determine soil carbon content. Due to non-uniform soil carbon depth distribution, the correlation between INS signals with some soil carbon content parameter is not obvious; however, a proportionality between INS signals and average carbon weight percent in ~10 cm layer for any carbon depth proﬁle is demonstrated using Monte-Carlo simulation (Geant4). Comparison of INS and dry combustion measurements conﬁrms this conclusion. Thus, INS measurements give the value of this soil carbon parameter.
