Dear all,

I am trying to simulate peanut crop growth using DSSAT 3.5. The treatments
comprized of moisture depletion levels and fertilizer doses including
organic residue.

I would like to know:

1. How dssat calculates evaporation on the day of rainfall or irrigation
since the upper boundary condition(soil surface) changes.

2. What equations are used to calculate each parameter in
CROPGROW980-PEANUT including water balance.

I would appreciate if someone helps me.

Thanking in advance.
