Hi everyone

I am trying to model the nitrogen cycle in my watershed using the SWAT+ Editor. For this, I created custom operations under management schedules. However, when I run these, the SWAT+ output check for the Nitrogen Cycle shows that no inorganic nitrogen fertilizer is being added as mineral nitrogen.


Does anyone know why this might be happening?

Thank you in advance

I am not sure about this issue exactly, but I have seen similar issues for crop nutrient uptake and biomass yield. the swat check shows 0, but when I go to the actual output txt files, there clearly is uptake and yield. So I would reccomend checking the actual output files to confirm for sure.

Hello,

Indeed, this image migrated from the old swat, and now the data is being gathered from a number of different sources. The reason why there are "0" at some points is that:
- either the necessary output wasn't printed (the user did not select to print the necessary files).
- the model does not report this output.
- the editor does not parse this information yet.


Best,
Natalja
