Human Urine for Fertilizer!!! - Scientific Research Proves it Works!!

#324047 - 11/30/09 08:16 PM (14 years, 11 months ago)

So I found a thread on here about using Urine in a Hydro setup. there were allot of people saying all sorts of different things, like it'll kill the plants and so forth. knowing this was false, I decided to do some extra research, seeing as there are only 4 threads on "urine as fertilizer" on the growery.

This is a great idea for most anyone to use. Especially in poverty stricken countries, where the cost to fertilize ones land is enormous. this is a great way to teach people to be self sustainable. Not having to rely on chemical fertilizers that bring in big bux for giant conglomerate chemical companies!!

Anyways, i hope someone finds this interesting. here it goes:

This is a scientific study published in The Journal Of Agricultural and Food Chemistry, that was conducted using urine to fertilize the tomato plant. It's great, you all should really read this one.

Stored Human Urine Supplemented with Wood Ash as Fertilizer in Tomato (Solanum lycopersicum) Cultivation and Its Impacts on Fruit Yield and Quality

http://pubs.acs.org/stoken/presspac/presspac/full/10.1021/jf9018917?cookieSet=1

Excerpt:
"The new study found that plants fertilized with urine produced four times more tomatoes than non-fertilized 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."

Quote:
Urine typically contains 70% of the nitrogen and more than half the phosphorus and potassium found in urban waste water flows, while making up less than 1% of the overall volume. Thus source separation and on-site treatment has been studied in Sweden as a way to partially close the cycle of agricultural nutrient flows, to reduce the cost and energy intensity of sewage treatment, and the ecological consequences such as eutrophication, resulting from an influx of nutrient rich effluent into aquatic or marine ecosystems. The fertilization effect of urine has been found to be comparable to that of commercial fertilizers with an equivalent NPK rating.

Excerpt:
" Urine as a fertilizer- Urine is a locally produced resource that is free. As a fertilizer it is effective, is a high quality fertilizer, urine is sterile and requires no processing other than dilution, is readily available, can be used immediately or stored, rapid acting, and is easily applied. Urine provides a constant supply of fertilizer, instead of the annual or semi-annual composting systems that require physical labor to aerate and require management.
As a fertilizer, urine is rich in nitrogen and also contains substantial amounts of phosphorus and potassium. A family of four produces enough urine to fertilize 1/3 of an acre at a rate compared to the application of 100kg per hectare in developed countries -note that Africa currently has the lowest fertilizer use in the world at 8.5kg per hectare. The use of urine as fertilizer has been studied by Arba Minch University in Ethiopia and the Sodo Agricultural Department investigated the use of human urine as fertilizer for different crops. Their research indicates equal or higher yields of maize and wheat when fertilized with urine when compared with the applications of chemical fertilizer."

Quote:
"Urine contains large quantities of nitrogen (mostly as urea), as well as significant quantities of dissolved phosphates and potassium, the main macronutrients required by plants. Diluted at least 8:1 with water it can be applied directly to soil as a fertilizer. Undiluted, it can chemically burn the roots of some plants, but it can be safely used as a source of complementary nitrogen in carbon rich compost."

Excerpt:
"Tushabe added that human urine is a good fertilizer because it contains nutrients that support plant growth.
He noted that in countries like Ivory Coast, Eco-san toilets have increased agricultural production by three-fold."

Last but not least here are a ton more links about the use of urine as a fertilizer. You too can find out by typing in "urine fertilizer" into Google!! In case ya'll aren't familiar with this procedure I have enclosed a link here that does just that for you!! :wink:
