c     asdsbk - Soil layer settled bulk density (Mg/m^3)

c              range values       min        max
c              ------------   ---------  ---------
c              fixed          ?          ?
c              typical        ?          ?
c              ------------   ---------  ---------

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

c     aszlyd - Depth to each soil layer for each subregion (mm)

c              range values       min        max
c              ------------   ---------  ---------
c              fixed          ?          ?

c              ------------   ---------  ---------

c            - This variable maintains the depth to each soil layer
c              for each of the subregions.
