Salt Influence

Only used when a SaltTracer is considered.

Value

Meaning

Not considered

Salt will not influence the water uptake or transpiration

Add minimum response

Salt will influence uptake by using an independent response function that will influence the water uptake rate directly. However this is only made if the value of the response is less than the valued as suggested by the water stress.

Add multiplicative response

Salt will influence water uptake by using an independent response function that will influence the water uptake rate directly. This is made by multiplication on top of other possible limitation functions.

Added to pressure head

Salt will influence water uptake as an integrated effect of the soil water potential. The osmotic pressure is added to the pressure head to obtain a total potential for the response of salt and moisture.
