Subject: Available Water Limits


Dear Members,
Can anyone tell me how to access the look-up tables, provided in DSSAT 3.5,
to determine plant available water limits?  Also, does anyone know of any
algorithms to estimate plant available water limits from textural
data?  Thank you for your help.

Derek McNamara
