13-this may not be entirely true. although the urine would go into the plants system, the plant can use processes like respiration (using glucose) that would change the way the urine would taste/ even exist inside the plant. if you water a plant with soda, the plant will not taste like soda once you wash it off. My bet is OP didn't wash the basil.
Actually it is broken down to its constituents, such as nitrogen, and used by the plant. Uric acid decomposes quickly. Human waste is used as fertilizer, but usually in poorer areas where choice isnt really an option; it's the risk of human pathogens in human feces. Op forgot to thoroughly wash the basil.
@70, it's very simple. Fertilizer comes from farms, typically pig/cow farms. The dung gets collected into a pool and can then be sprayed onto the field. Human faeces go into the sewers and mix with whatever we flush down there. People flush down diapers, make-up, toilet paper, soap, various chemicals from showers, makeup removal, washing machines etc. Most sewers also connect with the road network's drains, making various heavy metals go down into the same system as the potential fertilizer every time it rains. This means we'd have to purify the sewage before we could even consider using it for fertilizing plants. Human faeces and animal faeces are both used as fertilizer in fields. It's also fairly common for our compost to be turned into fertilizer as well. All farms handle their disposal of animal bi-products their own way, some cheap out and don't store it in tanks but rather dump it directly in nature or something else. But typically they should keep it in pools and basins until they can do something with it.
