Short summary

Soil organic matter (SOM) is essential for the health of soils, and the accumulation of SOM helps removal of CO₂ from the atmosphere. Here we present the result of the continued development of a mathematical model that simulates SOM and its measurable fractions. In this study, we simulated several grassland sites in the US, and the model generally captured the carbon and nitrogen amounts in SOM and their distribution between the measurable fractions throughout the entire soil profile.
