Abstract
Laboratory determination of carbon content in 30-50 kg soil samples is described. The method is based on the tagged neutron technique. Procedure for carbon determination in such samples was developed based on a physical model and Monte-Carlo simulations (Geant4) of neutron stimulated gamma spectra. Measurement results of samples with different density and moisture demonstrate good agreement with standard dry combustion analysis. Thus, this method can be recommended as an alternative for laboratory determination of carbon in 30-50 kg soil samples.
