I confess, my husband and I both pee in our backyard garden, waiting until nightfall so as not to surprise neighbors.
We’ve always been comfortable relieving ourselves alongside lonely highways, even in daylight when waiting for the next bathroom seems unreasonable. But peeing in our own garden started as something of a lark, a combo of enjoying feeling a little naughty while also stealing a moment to take in the stillness of the night.
However, after a little research into the contents of urine and the ecological footprint of toilet flushing, I’m approaching my nightly garden visitations with a renewed sense of purpose, armed with sound reasons to continue the habit.
#1 Urine is a good fertilizer, organic and free
Contrary to popular belief, urine is usually germ-free unless contaminated with feces. It’s also about 95 percent water. The chief dissolved nutrient is urea, a nitrogen (N)-rich waste metabolite of the liver. Consequently, urine is high in N. Synthesized urea, identical to urea in urine, is also the number one ingredient of manufactured urea fertilizers which now dominate farming industry. Furthermore, urine contains lower amounts of the other two main macronutrients needed for healthy plant growth, phosphorous (P) and potassium (K).
