Is soil fertility included in AquaCrop-OSPy?

[emdigman]

I am aware that in the standalone AquaCrop model there is a soil fertility function, as described in Section 2.3.8. of the FAO Water Report No.47. In this report it is listed as one of the "Field Management" variables.

Is this function present in AquaCrop-OSPy? Looking at the variables in the "Field Management" class in the Python package, I am not sure if any of these correspond to the soil fertility function, for example if "curve_number_adj" or "curve_number_adj_pct" are related to soil fertility in some way.

Is soil fertility currently represented in AquaCrop-OSPy, either in the field management class or in another section of the python package? If it is not currently included, are there an estimate of if/when it would be added to the model in the future?

Many thanks, Edward D.
