02-01-31 New options

Introduced options for the water uptake response to soil temperatures. These are preliminary suggestions and may be changed later. The documentation is not updated, so the present formulations are explained here:

Temperature response

"None"

 

"Double-exponential" (default)

 

"Single-exponential"

 

"Polynomial"

 

where the trigging temperature Ttrig can be a static parameter or a function of the accumulated daily average air temperatures above a threshold temperature (5°C default):

 

The switch "PlantDevelopment" must be set to "start=f(TempSum)" in order to use this function.

 

Temperature response parameters:

Name  Symbol         Function

TempCoefA    tA       Double-exp.

TempCoefB    tB       Double-exp.

TempCoefC    tC       static Ttrig

TempCoefD    T98% and T100%     Single, Polynom.

TempCoefE    tE       Polynomial

TempCoefF    tF       dynamic Ttrig
