Daily Dosage: An extreme way to use your pee
A little secret that gardeners everywhere already know: you can skip the fertilizer if you’re willing to tote a bottle into the bathroom. And now new research shows that pee is even better than we thought at watering crops.
Most experts used to recommend diluting urine in a 10:1 water solution. And they often suggested avoiding fertilization-by-urine with more delicate plants, which were sensitive to the liquid gold’s caustic nitrogen levels. But that’s no longer the case, at least when it comes to tomatoes. A study out of Finland found that using pure, unadulterated urine produced tomatoes with higher b-carotene content and less sugar.
But don’t go peeing all over your garden just yet. Be sure to drink plenty of fluids so that your output is relatively dilute, and if you’ve got a mega-dose of concentrated pee, use it as a weedkiller instead.
