Human urine is an excellent fertiliser with almost identical balance of nutrients to the commercial NPK-type fertilisers.
It is free abundant fast-acting. An excellent source of essential nitrogen phosphorus potassium and trace elements.
It’s strength is equivalent to commercial fertilisers. Dilute 1:10 for small plants weaker for pot plants but undiluted is ok for established plants and trees.
Fresh urine is sterile.
This is such an outstandingly valuable source of nutrients such as nitrogen that are a limited resource that entrepreneurs in Europe are already harvesting it from whole towns. They are paying to instal special toilets that separate out urine and channel it for collection. This bulk urine is then sold for nitrogen. A profitable business apparently.
