| | 50 | GRM_F_AUTOGESTION 0 1 : automaticly cut/mown for cut-and-carry forage (for managed but not cut not grazed grass PFT only) |
| | 51 | 2: automatically grazing by livestock to optimize (potential) livestock density (for managed but not cut not grazed grass PFT only) |
| | 52 | 3: searching for the curve of extra-feed requirement with increasing stocking rate (cut and grazed grass PFT) |
| | 53 | 4: searching for the curve of extra-feed requirement with constant stocking rate (cut and grazed grass PFT) |
| | 54 | 5: automatically grazing by wild animal (grazed grass PFT only; used for LGM simulation; need update with Dan's improvement) |
| | 55 | GRM_F_POSTAUTO 0 1: start from GRM_F_AUTOGESTION=2, running with variable optimized potential livestock density (cut and grazed grass PFT) |
| | 56 | 2: start from GRM_F_POSTAUTO=1, running with variable optimized potential livestock density (cut and grazed grass PFT) |
| | 57 | 3: running with constant livestock density (cut and grazed grass PFT) |
| | 58 | 4: running with constant livestock density but varied grazed fraction and stocking rate (cut and grazed grass PFT) |
| | 59 | 5: global simulation with prescribed management in GRM_input.nc (all grass PFT) |

| | 68 | GRM_AVOID_WETGRAZING 0 active soil moisture impact on grazing (i.e., avoil grazing over too wet soil, considering lag-effect) |
| | 69 | GRM_AVOID_SNOWGRAZING 1 active snow cover impact on grazing (i.e., avoild grazing when there is snow mass, considering lag-effect) |
| | 70 | GRM_F_AUTOGESTION=2 GRM_NB_CUT_YEAR 10 how many years were running under GRM_F_AUTOGESTION=1, used to calculate annual harvested grass cut-and-carry forage |
