Hi everyone,
I have one question about the nutrient competition with FUN open in the CLM.
I noticed that in the "SoilBiogeochemCompetitionMod.F90" module where CLM calculates the N competition between plant uptake, immobilization, nitrification and denitrification has two different variables that describe the nutrient to the plant. one is <sminn_to_plant_vr>, and the other one is < sminn_to_plant_fun_vr >, obvious, the latter one is the flux we use if we open the FUN model.
But in the code itself, it looks like < sminn_to_plant_fun_vr > is not the product flux after the nutrient competition but just from the FUN model patch level. I do see in the code, CLM only pass this module when < sminn_to_plant_fun_vr > is smaller than <sminn_to_plant_vr>, but does this mean the FUN model always predicts smaller plant uptake flux than the standard uptake scheme after nutrient competition?
