Review the use of all the parameters in the SPE file

[lpmorenoc]

Review if all the parameters in the SPE file are used and if they have proper values

[lpmorenoc]

• Removed LLIFX

• LLOSA currently no used but it is supposed to represent the accelerated senescence due to water or N stress.

• SLATS and SLATR are currently no used but it is supposed to represent the standard temperature for the specific leaf area and the rate of change when the temperature is lower than the threshold.

• RS%O defines the reserves concentration (after supplying the aboveground demand) above which overflow to the roots. Currently it is 2% although this parameter should probably be removed to allow total overflow.

• RWUPM is used as PORMIN to estimate root water uptake. RWUMX is also used for the root water uptake.

• WFEU and RWULF are used by a root water uptake subroutine that is not called by DSSAT (CSCRPROOTWU). Remove?

• WFPU and WFPL are used to estimate WFP but this coefficient is not really used to affect photosynthesis. WFP is used in the subroutine EVAPO but the results are not actually used by the model. Should I remove this section and also assign -99 for WFP?

• WFSU is used to define the threshold of leaf senescence due to water stress. However, this factor is currently defined as 0 in the model (no senescence due to water stress).

• NFSU is used to define the threshold of leaf senescence due to nitrogen stress. However, this factor is currently defined as 0 in the model (no senescence due to nitrogen stress).

• PARFC, CO2CC and CO2EX are not used. Represent a different method for CO2 response (from CROPGRO). They were removed.

• RATM and RCROP are used by the subroutine EVAPO whose results are not actually used by the model. Should I remove them?

Remove parameters no used:

• [x] Remove subroutine CSCRPROOTWU and the variables RWUPM and RWUMX from the cassava "growth" code (no longer used). d9c86544f11f8f9196bf27437714d1fdab174014 https://github.com/lpmorenoc/dssat-csm-os/commit/2a1010ab59d3bf6c407ebff76bb7c5b9b57749c1

• [x] WFEU and RWULF d48f1c08f71cb738ee575d5b951b9606d2f05bff

• [x] WFPU and WFPL. Assign WFP as -99. Remove subroutine EVAPO from cassava model. b72aec5768ff5fa6133dce24e804949201c3939b

• [x] RATM and RCROP 4dec4ff250f622bd604a21ca851ea9932aa6629c

Remove parameters used but that should not exist:

• [x] RS%O bb67069df1756169a213b90fcda4780bd8aa102a

Parameters that are still in the SPE file for potential use although currently do not have any effect: LLOSA, SLATS, SLATR, WFSU, NFSU

[lpmorenoc]

SLATS and SLATR are now implemented to represent the standard temperature for the specific leaf area (SLATS) and the rate of change when the temperature is less than this standard temperature (SLATR). Parameters in the SPE file deleted because they are not used currently 23844a2b:

• LLOSA
• WFSU
• NFSU
