Abstract

The proposed elementary mathematical model of formation and decomposition of soil organic matter (SOM) is based on using equations of chemical kinetics to describe the multistage process of SOM transformation. The model both describes each step of transformation in accordance with the law of mass action and postulates the trend of increasing stability of the matter towards further transformation, which is common for all steps. Analysis of the model demonstrates that it is extremely difficult to construct a realistic model of SOM dynamics by assembling elementary models of the type presented in this study into the full description of SOM transformation processes.
