 In OCN, drainage is used for removing part of the organic and inorganic N in soils. what is used, is a mean drainage for all the mesh. There is no distinction between the different soil water columns on which water balance is calculated (13 for choisnel or 3 for Cwrr). We correct this.

+=== stomate_litter ===
+I don't understand the original formulation in OCN that defines the flows of newly formed litter. See below
+{{{
+       ! new litter nitrogen is partitioned to metabolic and structural so as to preserve
+       ! a fixed ratio of C/N between the matter flows into the litter pools
+       !
+       ! aboveground nitrogen litter

+            bm_to_litter(:,j,icarbres,initrogen) + bm_to_litter(:,j,ilabile,initrogen) + & 
+            turnover(:,j,ileaf,initrogen)  + turnover(:,j,ifruit,initrogen) + & 
+            turnover(:,j,icarbres,initrogen) + turnover(:,j,ilabile,initrogen)
+       WHERE(litter_inc(:,imetabolic,j,iabove,icarbon).GT.min_stomate)

+               litter_n(:) / ( 1. + litter_inc(:,istructural,j,iabove,icarbon)/(5.*litter_inc(:,imetabolic,j,iabove,icarbon)))
