Try and avoid believing the myths we were taught. Urine fertilizer is called "Liquid Gold." Human urine properly diluted is excellent for plant growth and it's safe. A diluted solution anywhere from 10:1 to 20:1 (water to urine) is a great fertilizer. I have been using urine for many years in my gardens. Human urine could easily and safely be used in the ag and farming world in large scale operations or just for the backyard grower. It's kind of a shame that we let all that "waste" go to waste. :)
from an article: "Human urine is one of the fastest-acting, most excellent sources of nitrogen, phosphorous, potassium and trace elements for plants, delivered in a form that’s perfect for assimilation. Not only that, we all have a constant, year-round supply of it - and it's free!
Fresh human urine is sterile and so free from bacteria. In fact it is so sterile that it can be drunk when fresh; it’s only when it is older than 24 hours that the urea turns into ammonia, which is what causes the 'wee' smell. At this stage it will be too strong for use on plants, but poured neat on to the compost heap it makes a fabulous compost accelerator/activator, with the extra benefit of adding more nutrients....."
"Patrick Makhosi, a soil scientist with Uganda's Kawanda Agricultural Research Organisation, confirms the efficacy of human urine as a fertiliser. He says that applying urine to growing vegetables once every week for at least two months will more than double the yield."
"In 1975, Dr A. H. Free published his book
Urinalysis in Clinical Laboratory Practice, presenting a few of the critical nutrients found in urine, including urea nitrogen, urea, creatinin nitrogen, creatinin, uric acid nitrogen, ammonia nitrogen, amino nitrogen, sodium, potassium, calcium, magnesium, chloride, inorganic sulphate and inorganic phosphate."

from the article: "The nutrients in urine are also in just the right form for plants to drink them up, says Håkan Jönsson, a researcher at the
Swedish University of Agricultural Sciences in Uppsala who was not involved in the beet study but has researched urine recycling for over 15 years. Food gives us nutrients like nitrogen as parts of complex organic molecules, but our digestive system strips them down into the basic mineral form that plants need—so "we have done half of the job," Jönsson says."
