Go with the flow.....

Scientists at the University of Kuopio in Finland grew cabbages using a 
conventional fertilizer, human urine that had been stored for 6 months, 
or no soil amendment at all.  The researchers report that the urine 
treatment yielded cabbages that were bigger and carried fewer germs than 
those grown by either other approach.  Analyses of the urine used in 
these experiments showed that its nitrogen, phosphorus, and potassium 
contents were comparable to those of commercial fertilizer. Urine 
collected from one individual over the course of a year could fertilize 
a 90-square-meter plot, yielding more than 160 cabbages, the team 
calculates. The data indicate that a urine-treated plot would yield 64 
kilograms more cabbage than one fertilized conventionally. (SCIENCE 
NEWS, 2007)
