In the results of NDR, the average value of N or P export is smaller than that of modified_load N or P. I think it’s reasonable. But the maximum value of N or P export is larger than that of the modified_load N or P. As a result, modified_load minus export will appear negative values. Is it a wrong result because of the negative values in retention? Is there a way to solve this? Thank you!

Hi @Momo1, welcome, and thanks for your question!
First, I want to point you this caution about directly interpreting absolute values in NDR results.
That said, this does seem like an unexpected result. Are you able to share your data? If so, we could take a look and see if we can find what might be causing this behavior.
