Hiroshi :
 
I do not think that anyone has really tested the soil temperature submodel
in the DSSAT models.
 
Most of the recent changes in the crop models are documented in
"Understanding Options for Agricultural Productions," published by Kluwer
Academic Publishers and edited by Tsuji et al.
 
 
Regards,
 
Gerrit
