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
