Talk about your high yuck factor. Researchers in Finland have just published results of a study showing that farmers can substitute human urine for conventional fertilizer and get a notable increase in cabbage yields.
Surendra K. Pradhan of the University of Kuopio and his colleagues grew cabbages using a conventional fertilizer, human urine that had been stored for 6 months, or no soil amendment at all. In an upcoming issue of the Journal of Agricultural and Food Chemistry, the researchers report that the urine treatment yielded cabbages that were bigger and carried fewer germs than those grown by either other approach.
