Piss has been used as a fertilizer since the beginning of human history...
Since you ingest (hopefully) fruits and vegetables that have the major and minor nutrients, those will get passed in your urine and feces...
Just keep in mind that if you take acid, aspirin, or take xtc..
that will get passed in your urine too....
One positive about urine... is that it tends to be acidic so it lowers the pH of the native soils of Hawaii that typically tend to be alkaline rich clays..
In your belly, once your liquid hits your kidney, the reaction that takes place there actually acidifies the urine and lowers it a full point or two...
Keeping this theme in mind...
People get freaked out when they realize that about 80% of our seed derived crops (tomatoes, grapes, etc) history is full of shit!!!
Many seeds have to be digested to become activated... It's our acidity that activates them before we poop them out!!!
Professional seed companies have to process the seeds we buy in stores with chemicals to simulate that process..
