c     This common block consists of variables that contain the crop
c     property values that are "eventually" going to be moved into the
c     "decomp" pools.  Thus, these are used for temporary storage
c     before that transfer occurs, ie. like a "temporary" pool.
c     
c     Management "effects" that will deposit crop material (values)
c     into the "temporary" pool variables are:
c     
c        cut - standing live crop mass to temporary crop flat mass
c       flat - standing live crop mass to temporary crop flat mass
c              (does the same thing as cut at a height of zero)
c       kill - all crop biomass pools are moved to the temporary
c              mass pools.
c     
c     The "transfer" management effect then moves the values from the
c     temporary pool variables to the "decomp" pool variables.
