In conclusion, this study has provided a comprehensive understanding of the properties, strengths, and weaknesses inherent in the coarse-grained SOM model. Serving as a robust foundation for further research, this model offers opportunities to explore the diverse compositions of SOM. Moreover, it sets the stage for investigating interactions with soil substances and pollutants within the Martini 3 force field framework. This comprehensive analysis marks a significant step forward in our understanding of SOM dynamics and its broader environmental implications.
