Soil carbon sequestration can be estimated from field to global scale using numerical
soil/ecosystem models. In this chapter, we describe the structure and development of
models that have been widely used at international level, from simple models that include
carbon only to models that include descriptions of the dynamics of a range of nutrients. We
also present examples of the application from field to global scale of different models to
answer a range of different questions on the impact of land use and climate changes on soil …
