[Terrapreta] Caution on Urine

[Gerald Van Koeverden]

David,

Sounds more like plant food to me...?

"The urine, or yellow water, contains the highest proportion of  
natural nutrients (nitrogen,
phosphorus and potassium), which are directly available to plants and  
equally effective as
mineral fertilisers. Urine contains approximately 90% of the total  
nitrogen, 55% of the total
phosphorus and a substantial portion of the potassium contained in  
human excrement."
