SUBROUTINE splitsoilini (fileheader,nx,ny,nzsoil,nstyps) 1,5
!------------------------------------------------------------------------
! HISTORY:
!
! Yunheng Wang (09/06/2001)
! Update with the new version ext2arps changed by Gene Bassett.
! In general, a variable soiltyp was added in soil initial
! file (xxxxxx.soilvar.000000) by Gene.
!
! Deallocate all the allocated variables
!
! Yunheng Wang (07/15/2002)
! Updated for new ARPS version (IHOP_3)
