can fertilizers used growing terrestrial plants cause nitrites?

[mellowvision]

I'm curious. some plants I've been interested in come potted in organic soil... and I'm wondering if this will contribute to nitrite levels in a paludarium environment.

If the soil contains a lot of organic material (which it should if it's organic) it can add to the bioload of the tank yes.

I think it would be wise to carefully remove the plant from its pot roots and all, rinse off the potting soil, and replant in your aquarium substrate.
