I have been saving my urine for the past few weeks. There are lots of applications for it. Urine makes a excellent pesticide, insecticide, and fertilizer. Today I was using it to kill weeds by giving them pure undiluted piss. If you want to use urine as a fertilizer be sure to dilute with 8 parts water per one part urine and do not pour it directly on plants. Urine can be used very efficiently with grey water for plant irrigation.
