v17 v18 20 20 It would be better if the routine could recognize missing values and remove them from the interpolation. 21 21 22 23 22 === Reading in N inputs === 24 23 The variables storing the N inputs in the restart file are all undef. Not quite sure why. I set them all to zero. … … 32 31 Meyerholdt & Zaehle (2015) showed that model predictions best matched available data when the C:N ratios in all ecosystem pools except the wood pool were treated as flexible. However, there is substantial variation in wood nutrient content found along a gradient of soil fertility (Heineman et al., 2016) and the wood N and P concentration correlates with leaf N and P concentration. 33 32 34 35 33 Due to this contrasting findngs, I am not sure if we should change the approach of OCN in which cahnges in wood stoichiometry follows leaf stoichiometry. 34 One could argue that the stoichiometry in model is too fast in adapting (to satisfy Meyerholdt's finding) but it is flexible and follows leaf stoichiometry (Heineman observations). 36 35 37 36 === Effect of nutrient stress on root/leaf ratio ===
