Pools name used in (model = GPASOIL-v0) | Pools definition used in (model = GPASOIL-v0) | Hedley fractions considered on sites used in Ringeval et al.11 | Pools name used in (model = GPASOIL-v1) | Pools definition used in (model = GPASOIL-v1) (following He et al.14) | Corresponding with Hedley fraction used in He et al.14 |
---|---|---|---|---|---|
PILAB | Labile inorganic P | [H2O Pi/Resin Pi+] Bicarbonate Pi | Pi-solu | Inorganic P in soil solution | H2O Pi/Resin Pi + Bicarbonate Pi |
Pi-lab | Labile inorganic P | ||||
PSEC | Inorganic P bound on secondary minerals | Hydroxide Pi [+Sonic Pi] | Pi-sec | Moderately inorganic P | Hydroxide Pi |
POLAB | Labile organic P | [H2O Po + Resin Po+] Bicarbonate Po | Po-lab | Labile organic P | Bicarbonate Po |
POSTA | Stable organic P | Hydroxide Po [+Sonic Po + HCl Po] | Po-sta | Moderately organic P | Hydroxide Po |
PAPA | Apatite | HCl Pi (HCl diluated or not) | Pi-prim | Primary inorganic P | HCl Pi (HCl diluated only) |
POCC | Occluded inorganic P | Residual P [+Hot HCl] | Px-occ | Occluded P (inorganic + organic) | Residual P [+Hot HCl P + Sonic P] |
Squared brackets in columns 3 and 6 are used for Hedley fractions which are not systematically quantified. Columns 2 and 3 were adapted from the Table 2 of Yang and Post79. Please, note that all occluded P was considered as inorganic P in Ringeval et al.11 while this was not stated in Yang and Post79.
