!=======================================================================
! CROPSIM-CERES CEREAL GROWTH AND DEVELOPMENT MODULE Version 010115
!
! Last edit 050415 Changes to the way Gencalc runs handled
!
! Developed from Ceres3.5 and Cropsim.
! Ceres was modified to fit within the frameworks of Cropsim and CSM,
! and to conform to a number of the concepts that were used in the
! construction of Cropsim and CSM ... completion of all rate
! calculations before state variable updating, no embedding of
! variables in the code, modules to read their own inputs and to
! generate their own outputs,etc.. In so doing, a number of formulae
! in the original Ceres with embedded coefficients were simplified and
! the coefficients placed in external 'coefficient' files (cultivar,
! ecotype, or species), and some concepts (eg.how vernalization and
! senescence are dealt with) and tools from Cropsim were used. This
! modified model should thus not be considered as Ceres, but as a
! derivative of Ceres best referred to as Cropsim-Ceres rather Ceres
! per se..
!
! The module is used within both the Cropsim and CSM models.

! Substantive changes as worked on comparison
! 1. Reserves overflow. Introduced

! Fibonacci factors to match CSCRP
! AMIN1 function for stresses (instead of multiplicative)
! Assimilates factor talen out
! 3. Leaf appearance. Fof barley, rate of change of daylength
! algorithm taken out.
! 4. Introduced RSUSE to help maintain leaf growth
! Need to change.
! 1. Seed reserves (ch2o and N use and early root growth.
! For incorporation in CSM should:
! Change argument above.
! Eliminate '!' from SUMVALS call.
! Comment out call to Disease module.
! Changes for 4.50
!
! A. Changes that should not affect results.
!
! 1. Added subroutine code to the main program for those
! subroutines used when running in CSM. Deleted the
! subroutines.
! 2. Cleaned the list of variable declarations.
! 2. Added a few additional outputs, especially to WORK.OUT
! 4. Added outputs (-99's mostly) when run stops because
! of missing weather or equivalent problem.
!
! A. Changes that MAY affect results.
!
! 1. Took out the 0.6 adjustment for RLWR (SPE file) that stemmed
! from the original Ceres 'exudation' loss of dry matter sent
! to the roots. With the 0.6 factor the 'real' RLWR parameter
! would have been 1.633. It was left at 0.98 rather than being
! changed to 1.633 because there was very little water stress
! being predicted for experiments in which there should have
! been stress.
!
! 2. Set upper water threshold for photosynthesis (WFPU in ECO
! file) to 1.0 following discussion with KJB.
!
! 3. Set upper water threshold for growth (WFGU in ECO
! file) to 1.3 following discussion with KJB.
!
! 4. Brought the soil fertility factor SLPF into the
! module and now use it to modify photosynthesis in conformity
! with other CSM crop modules.
!
! 5. Brought the planting date when running a sequence in CSM
! (ie.under DSSAT) across from the planting section
! of CSM.
!
! 6. Brought the harvest fractions (both product and by-product)
! when running in CSM (IE.under DSSAT) across for
! all modes of operation.
!
! 7. Changed the planting coding to ensure that neither
! growth nor development occur on the day of planting. This
! contrasts with the previous version, in which growth and
! development ocurred on the day of planting. Phenology will
! be affected by this change.
!
! 8. Changed the meaning of the so called water factor for root
! growth (WFRG) in the species file. It previously was
! interpreted as a multiplier to be applied to the soil water
! 'potential' to determine the degree to which root
! growth would be reduced below potential. It is now
! interpreted as an upper threshold value that is applied
! to the soil water 'potential' to determine the factor
! (now called the water factor for root growth) used to
! reduce root growth below potential. The change
! alters the degree to which root growth is reduced in
! layers in which the water content is below the upper
! limit. The parameter can be VERY IMPORTANT. It is now
! used 'as is' (not the square root) in the algoorithm for
! root depth growth.
!
! 9. Eliminated the second root growth water factor (WFRDG),which
! was used as a multiplier to determine the impact of the
! photosynthesis water factor on root depth growth.
!
! 10. Took out the N factor from the algorithm determining root
! dry matter distribution with depth.
!
! 11. Corrected the algorithm used to calculate water 'potential'
! at the seed depth. Previously, if seding was in layer 1, the
! algorithm was always giving the potential of layer 2. It
! should produce an interpolated value, which hopefully it
! now does.
!
! 12. Introduced code to re-initialize the leaf loss through cold
! parameter so that leaf area did not continue to be lost
! after a cold spell ended.
! Needed!
! 1. Leaf # and time to terminal spikelet too great
! when leaf # > 15. Need limit. See LAMS
! 2. Yield and kernel # from early and late plantings
! high. Need stress factor that affects kernel set
! See MCCR
! 3. Reserves can go to zero during grain fill, then
! recover. Need accelerated senescence! See KSAS.
! 4. The saturation factor for water uptake (SATFACL)
! gave far too great stress for one Australian data
! set (CSGR9802). It is now controlled (for standalone
! Cropsim, not CSM) by a switch in the ecotype file
! that is currently set to 0 .. hence no saturation
! effect. Need to use switch in CSM somehow.
