Dear All
I am using DSSAT for simulation of soybeans and maize across different
soil types.
I have been looking at the outputs and would like to know if anyone
could provide me with further information to explain the following
outputs from the growth aspects output file;
Water stress - photosynthesis WSPD
Water stress - growth WSGD
Nitrogen stress factor NSTD
Excess water stress EWSD
One of the reasons why I am asking is that in some cases I have outputs
where both water stress and excess water stress are high, and others
where water stress is high and excess water stress is low. I am
assuming excess water stress is when there is high soil water close to
saturation, which seems to match my outputs. However, I am unsure if
the water stress growth and photosynthesis in these outputs occur during
both wet conditions and drought conditions.
Any advice will be much appreciated.
Thanks
Wendy
