When I read this article I felt validated. I've been promoting the use of urine and weed tea as a replacement for fertilizer created from petroleum. Urine contains nitrogen and phosphorous as well as many other trace elements necessary to plants.
In order to sanitize urine, it can either be stored for 30 days in
a sealed tank at room temperature, or heated
for 30 minutes in a solar pasteurizer.
I work at home so I was able to save about 70% of the urine I produced, and in 2013 I easily filled a 55 gallon drum. This will drum remained sealed for at least 3 months.
Since the urine is added the system's water and the water wickes up through the soil I see no possibility of contamination, but others may not feel comfortable so I will let the humona (human urine) age for their peace of mind.
