91 | | 6. nitrogen demand for new biomass problem, I think in the code, the N demand for the new biomass is not equal to bm_alloc. Two problems: 1) the growth_resp is already subtracted before, and do not need to add (1-frac_growthresp(j)) to calculate N demand; 2) bm_alloc_tot should be equal to sum of bm_alloc = bm_alloc_tot(ipts,j) - residual(ipts,j). Here I think it is better to use the demand as the total new biomass allocated in one timestep. |

| 92 | DSG: I can confirm, (1-frac_growthresp(j)) must not be subtracted. |
