Dear Users,
Hi again, I want to use automatic irrigation facilities in DSSAT. But
I cannot understand how it works. It has some variables:

1) Management Depth
2) Threshold %
3) End point %

I was thinking that the irrigation depth was calculated as :
(FC - PWP) * Zroot * MAD

I set Lower Limit in my soil profiles all to 0 and Upper limit all to
0.2 and Saturation to 0.5 (as an example). But the irrigation depths
were not equal to the ones I calculated with above formula. I think my
mistake is about he meaning of the above three variables.
Please someone help me to understand the problem. The model manual is
really weak!
