Difference in design between soil P pool dynamics model used in this study (model = GPASOIL-v1, panel (b)) and used in Ringeval et al.11 (model = GPASOIL-v0, panel (a)). Inorganic pools are in blue, organic ones are in orange and grey pools correspond to pools which encompass both inorganic and organic P forms. Double arrows means that an equilibrium is considered. Nomenclature used to name the pools changed between (model = GPASOIL-v0) and (model = GPASOIL-v1).
