The vertical distribution of soil organic matter predicted by a simple continuous model of soil organic matter transformations

Quantitative description of vertical organic matter distribution in real soil profiles by means a simple continuous model

“…Then, we proposed a modified model, which established a one-to-one correspondence between the stationary SOM distributions along the transformation rate and along the depth in soil profile. For that model, we demonstrated qualitative correspondence of the patterns of SOM vertical distribution curves to those for various types of real soils (Bartsev and Pochekutov, 2016). Although derivation of model equations in the previous papers Pochekutov, 2015, 2016) was described in terms of the classical theory of humification (Essington, 2004), the model can be used within the framework of both this theory and any other SOM transformation concepts that suggest a gradual increase in SOM stability toward transformation and decomposition.…”
