Urine


I read somewhere that human urine is so high in nitrogen that you could easily fertilize a 40 x 40 foot garden with it.

Urine is very high in nitrogen. For use mix 1 cup per gallon of water. It's absorbed quickly so keep in mind of other slower release forms of nitrogen that you may have already in the medium. The plants should kept on a high nitrogen regime until they are put in to the flowering regime. Signs of low nitrogen are excessive yellowing of leaves from bottom up. Too much nitrogen will show burning spots on the leaves.

Any kind of urine can be used as fertilizer as long as you pre-mix it with 3 times the amount of water prior to applying on nitrogen loving plants. So say the people at Biolet composting toilets.
