I am trying a new type of fertilizer that is abundant and free. It is high in nitrogen and freaks my wife out. This is my own pee, a great natural fertilizer.
For the record, pee is sterile. It makes a great addition to compost piles, shrubs, trees and vegetable gardens. People that have an issue with pee used in a garden as fertilizer must not have an issue with eating plants dowsed with herbicides, chemical fertilizers and pesticides. As a fertilizer, my pee is not crop dusted over the fruit or leaves. The mix is 10 parts water and 1 part pee. Then it is poured around the base of the plant.
More information about pee can be found at Wikipedia. According to Wikipedia, pee is 95% water. The rest is urea 9.3 g/L, chloride 1.87 g/L, sodium 1.17 g/L, potassium 0.750 g/L, creatinine 0.670 g/L and other dissolved ions, inorganic and organic compounds. Urea contains the nitrogen boost. In fact, pee as a fertilizer is a little hot; therefore, it should not be directly applied to plants without diluting with water.
As a personal testimonial, on two separate occasions I had Kiwis that were withering with yellowing leaves. I put a mixture of my natural pee fertilizer around their base for a couple of days in a row. The leaves turned green and the plant started to aggressively vine again. I also used my natural pee fertilizer when I saw my cucumber leaves turning yellow. The leaves turned back to green again.
Finally, using pee saves water because it is not flushed down the toilet.
