C CSP_DEMAND, Subroutine, from DEMAND subroutine
C by J.W. Jones and G. Hoogenboom.
C-----------------------------------------------------------------------
C Calculates potential demand for C and N based upon new growth and
C existing N deficiency in old tissue.

C 08/22/1995 GH Added seed composition routine from KJB & ELPiper
C 04/02/1996 JWJ Modified partitioning during early growth
C 01/10/1997 GH Added TURFAC effect on seed growth and pod addition
C 09/15/1998 CHP Modified for modular format
C 05/10/1999 GH Incorporated in CROPGRO
! 11/08/2001 O.H. Daza modified for the sugarcane model
