Urine is chock full of nitrogen, potassium and phosphorus, which are the nutrients plants need to thrive—and the main ingredients in common mineral fertilizers. They can also lead to anxieties and shyness while using one.

Use more for plants such as cucumbers, squash, tomatoes and corn that need more nitrogen to put on fruit. The usage of urine in our agricultural products would lessen the impacts of industrial fertilizers on the environment (Grunbaum, 2010). Don’t worry, the researchers ask themselves the same question. Some say to age it atleast 6-16 months before use and some say let it sit for atleast 24 hours before use. Long-term urea use lowers soil pH, making nitrogen and other nutrients less available to plants. I didn't put it on the leaves! Thanks to it’s nitrogen content, human urine is a high-quality fertilizer. “Urine Separation — Closing the Nutrient Cycle,” the exhaustive Swedish study of using urine as a fertilizer, compares the pros and cons of using solid human waste and liquid human waste to help grow crops.
