Pee on your Compost

Judging from comments and our web statistics you people out there love discussing poo. So it’s about time that we move on to pee. Why waste your perfectly good urine? Indeed, both Ghandi and Jim Morrison drank their own urine for it’s reputed health benefits. But we ain’t gonna go there.

Our suggestion for the day is to save that piss for your plants. Urine is a fantastic source of nitrogen and it’s estimated that we all produce enough urine to fertilize all the wheat and corn that we as individuals consume. And urine is sterile and safe unless you’ve got a bladder infection.

Urine should be diluted before applying directly to plants since salts in your pee can build up in the soil. Dilution should be at least 10 parts water to one part urine. Peeing directly on plants can burn them as anyone who owns a dog already knows about. Urine is easiest to apply to non-food crops, though it’s perfectly safe to use on fruit trees and bushes. Applying it to root crops is more controversial, and frankly seems like a practice best left to hippies, so if you try this at least cease application at a respectable interval before harvesting.

There is even a book called Liquid Gold on the subject of pee as fertilizer and the ever more resourceful Europeans have developed a number of urine diverting flush toilets similar to the one we profiled earlier to take the labor out of urine saving.

Perhaps the most convenient way to use urine is to simply pee on your compost pile. That way you don’t need to worry about saving it in a container and diluting it. As, no joke here, British conservative member of parliament Francis Maude puts it,

“If I share a tip with the audience it is that if you pee on your compost, it has a double environmental whammy – it speeds up its decomposition so you can get it on the garden more quickly, and it also saves water.”

  1. I bought some vegetables from a roadside farmer. They smelled of strong urine after I got into my car. I was hoping that my mind was playing tricks on me, so I asked others to smell them. I did not tell them my thoughts until after they told me quickly, “Pee!” With that settled, I dumped the vegetables. I do not want my vegetables grown with urine. Because I do not know what is added to the soil of others, I do not trust. I am raising my own vegetables. I planted a winter garden a month ago, and I am already enjoying some of my produce. I have compost “cooking” in my bin and can barely wait for spring planting.
