Zusammenfassung
We present a theoretical calculation of the fractionation factor during the uptake of molecular hydrogen by soil. It is based on an analytical expression for the deposition velocity that considers molecular diffusion through a dry top soil layer without H2 removal into a deeper moist layer with enzymatic H2 removal and H2 production. The so derived fractionation factor depends on soil moisture and will be compared to existing field measurements on forest soil by Rice et al. 2011.
