277 | | The use of the hydraulic architecture model of Hickler et al (2006) designed for tree for grass seems problematic. |
278 | | Technically, the parameter "k_sap" is used in function "calculate_c0_allo"c but not defined for non-Tree PFTs resulting in "NaN" for calc_c0_alloc. |
279 | | I did a dirty fix by setting "c0_alloc= 2.0" to avoid NaN for non-Tree PFTs. |

| 275 | == 8. Parameter value not set == |
| 276 | The value of k_sap for crops and grasses was set to "undef". New value of 3.e-4 (personal communication Sebastiaan Luyssaert). |
