I was watching Daily Planet and saw them talking about this,thought it was pretty interesting...





Results of the first study evaluating the use of human urine mixed with wood ash as a fertilizer for food crops has found that the combination can be substituted for costly synthetic fertilizers to produce bumper crops of tomatoes without introducing any risk of disease for consumers. The study appears in the current issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.
In the study, Surendra Pradhan and colleagues point out that urine, a good source of nitrogen, has been successfully used to fertilize cucumber, corn, cabbage, and other crops. Only a few studies, however, have investigated the use of wood ash, which is rich in minerals and also reduces the acidity of certain soils. Scientists have not reported on the combinaton of urine and wood ash, they say.
The new study found that plants fertilized with urine produced four times more tomatoes than nonfertilized plants and as much as plants given synthetic fertilizer. Urine plus wood ash produced almost as great a yield, with the added benefit of reducing the acidity of acid soils. "The results suggest that urine with or without wood ash can be used as a substitute for mineral fertilizer to increase the yields of tomato without posing any microbial or chemical risks," the report says.

urine is nitrogen, and i believe wood ash is phosphorus
i think you cut urine at 1/10 ratio

Nice research. Rept. Anyone else know anything more about the actual application of cheap/free nonsynthetic fertilizers? I'm runnin low on Foxfarm and don't wanna keep buying it, even though it works like gangbusters
