Originally in: https://github.com/danipilze/dssat-csm/issues/57 Some aspects of nitrogen and CO2 effect need revision. Discuss the following parameters and how they are used in the model:

[x] NTUPF N top-up fraction (/d)
[x] LN%S Leaf N concentration,standard,early and late in life cycle (fr)
[x] LN%MN Leaf N concentration,minimum,early and late in life cycle (fr)
[x] SN%S Stem N concentration,maximum,stage (fr)
[x] SN%MN Stem N concentration,minimum (fr)
[ ] RN%S Root N concentration,maximum,sstage (fr)
[ ] RN%MN Root N concentration,minimum (fr)
[ ] NLAB% N labile fraction,standard %
[ ] NFGU N stress factor,growth,upper (fr)
[ ] NFGL N stress factor,growth,lower (fr)
[x] NFSU N stress factor,senescence,upper (fr)
[ ] NLLG N limit,leaf growth (fr.max.N%)
[ ] NCRG N factor,root growth (ppm)
[x] PARFC Maximum photosynthesis relative to phs at 330 vpm CO2 (#)
[x] CO2CC CO2 compensation concentration (vpm)
[x] CO2EX Exponent for relationship between CO2 and photosynthesis (#)
[x] RWULF Root length factor,water uptake (cm/cm3)
[ ] CO2F CO2 factor,photosynthesis,relative (0-2) and CO2RF CO2 reference (vpm)

NTUPF was removed a6c1bc5f1dd6fa73fd2918fd1ce27f6a625ccda9 NFSU, PARFC, CO2CC and CO2EX were also removed.
