2015年12月23日 · In this review we first provide an overview of SOM modeling, focusing on SOM theory, data-model integration, and model development as evidenced by a quantitative review of SOM literature. Second, we present the landscape of SOM model applications, focusing on examples in climate change policy.

2011年5月24日 · We present the vertically explicit soil organic matter model SOMPROF. Test simulations show that the model produces realistic carbon stocks and profiles. Simulations show that the SOM profile strongly affects the respiration variability.

2013年8月10日 · Here, we present AggModel, a conceptual and simulation model that integrates soil aggregate and SOM dynamics. In AggModel, we consider unaggregated and microaggregated soil that can exist within or external to macroaggregated soil.

2023年12月16日 · The accurate measurement of soil organic matter (SOM) is vital for maintaining soil quality. We present an innovative model for SOM prediction by integrating spectral and profile features. We use PCA, Lasso, and SCARS methods to extract important spectral features and combine them with profile data.

Our new model (MEMS v1.0) is developed from the Microbial Efficiency-Matrix Stabilization framework, which emphasizes the importance of linking the chemistry of organic matter inputs with efficiency of microbial processing and ultimately with the soil mineral matrix, when studying SOM formation and stabilization.

1997年1月15日 · SOMM, a simulation model of soil organic matter mineralisation, humification and nitrogen release, has been elaborated. The model takes into account the rate of the processes depending on litter fall's nitrogen and ash content, temperature and moisture.

2016年11月22日 · The grassland/crop and forest systems have different plant production submodels which are linked to a common soil organic matter submodel. The soil organic matter submodel simulates the flow of C, N, P, and S through plant litter and the different inorganic and organic pools in the soil.

2015年12月23日 · In this review we first provide an overview of SOM modeling, focusing on SOM theory, data-model integration, and model development as evidenced by a quantitative review of SOM literature. Second, we present the landscape of SOM model applications, focusing on examples in climate change policy.

Thus, it is important to understand how soil organic matter is formed, stabilized, and lost. Here, we review conceptual frameworks that have contributed to our understanding of soil organic matter over the past 20 years. We evaluate their support in experiments and also how well represented they are in computer models.

2024年12月18日 · This review examines the achievements of the last decade in modeling the role of microorganisms in the stabilization of soil organic matter, the concept of soil saturation with organic carbon, and temperature control, as well as the development of reactive transport models describing the dynamics of organic carbon in the soil profile and the ...
