just to begin...
1) You ingest nitrogen as amino acids in protein
2) you excrete acid in urine
so...
You have a +ve nitrogen balance when you're accumulating it in your body, when you're eating more proteins than you're peeing out nitrogen.
You have a -ve nitrogen balance when you're peeing out more when you're ingesting.
Also, your muscles are a major store of nitrogen in protein form. So when you're starving and burning up your muscle for fuel you're going to be losing nitrogen from your body.
Also, when you're growing or producing new tissue or something and increasing the amount of protein in your body you'll have a positive nitrogen balance since the protein that you're ingesting will be going to build new tissue.
This is just the basics... maybe someone can add...

Ill start with --negative N balance:
90% is excreted in the urine
negative N balance means the persons intake of protein is less then the daily breakdown of protein (the body store of protein are decreasing daily
