c     asdblk  - Soil layer bulk density for each subregion (Mg/m^3)

c              range values       min        max
c              ------------   ---------  ---------
c              fixed          fmin       fmax
c              typical        tmin       tmax
c              ------------   ---------  ---------

c            - This variable maintains the soil layer density values
c              for each of the subregions.

c     asdwdb  - Soil layer bulk density at 1/3 bar for each
c               subregion (Mg/m^3)

c              range values       min        max
c              ------------   ---------  ---------
