Parameters (for plant carbon inputs, exogenous organic matter carbon inputs and soil organic carbon mineralization) related to the AMGv2 model. These parameters are provided by the AMG Consortium (which includes INRAE, Agro-Transfert Ressources et Territoires, Arvalis Institut du Végétal and LDAR) and by Terres Inovia. They are applicable for average French arable crop conditions. A full description of the AMGv2 model can be found in Clivot et al. (2019): https://doi.org/10.1016/j.envsoft.2019.04.004
