+The nutrient demand  must be calculated AFTER the final Cl_init and Cr_init are known.
+This can be fixed by:
+
+{{{
+                ! The biomass available to use is set to be the minimum of the biomass of 
+                ! the labile pool (if carbon not taken from the atmosphere), and 
+                ! the wanted biomass.
+                bm_use(i) = MIN( biomass(i,j,ilabile,icarbon) + biomass(i,j,icarbres,icarbon), &
+                     bm_wanted(i) )
+
+     !DSGdebug_02           ! the nutrients need to support the biomass: 
+     !DSGdebug_02           bm_wanted_n(i) = (Cl_init +  Cr_init*fcn_root(j))/cn_leaf_prescribed(j)
+}}}
+[...]
+{{{   
+                ! In case nitrogen or phosphorus is not sufficiently available
+                ! downregulate new leaf biomass to respect leaf stoichiometry;
+                ! DSG: this violates the ratio used to calculate the
+                ! leave-root-sapwood relationships: is this OK?
+
+     !DSGdebug_02: moved after Cl_init and Cr_init are updated 
+                ! the nutrients need to support the biomass: 
+                bm_wanted_n(i) = (Cl_init +  Cr_init*fcn_root(j))/cn_leaf_prescribed(j)
