So who all does it? I know @Seamaiden does ;) strange gurl that one eh ;) *Jokes*

Ok seriously tho who else is mining this golden fountain of fertilizer?

What all nutrients does it provide the soil? Are they slow release? What benefits do you feel pissing or adding the piss to your garden has had?

Is piss a good source for nitrogen?

How much piss is too much piss?

Does it HAVE to be diluted to add to a growing bed, Or can you just piss on the plants and call it a day?

More questions as i think of them ;)

"About 91-96% of urine consists of water.[3]Urine also contains an assortment of inorganic salts and organic compounds, including proteins, hormones, and a wide range of metabolites, varying by what is introduced into the body.

The total solids in urine are on average 59 g per person per day. Organic matter makes up between 65% and 85% of urine dry solids, with volatile solids comprising 75–85% of total solids. Urea is the largest constituent of the solids, constituting more than 50% of the total. On an elemental level, human urine contains 6.87 g/L carbon, 8.12 g/L nitrogen, 8.25 g/L oxygen, and 1.51 g/L hydrogen. The exact proportions vary with individuals and with factors such as diet and healts

What Is the Chemical Composition of Urine?
By Anne Marie Helmenstine, Ph.D., Chemistry Expert
Updated March 11, 2016.
Question: What Is the Chemical Composition of Urine?

Urine is a liquid produced by the kidneys to remove waste products from the bloodstream. Human urine is yellowish in color and variable in chemical composition, but here is a list of its primary components.

Answer: Human urine consists primarily of water (91% to 96%), with organic solutes including urea, creatinine, uric acid, and trace amounts of enzymes, carbohydrates, hormones, fatty acids, pigments, and mucins, and inorganic ions such as sodium (Na+), potassium (K+), chloride (Cl-), magnesium (Mg2+), calcium (Ca2+), ammonium (NH4+), sulfates (SO42-), and phosphates (e.g., PO43-).


A representative chemical composition would be:

water (H2O): 95%

urea (H2NCONH2): 9.3 g/l to 23.3 g/l

chloride (Cl-): 1.87 g/l to 8.4 g/l

sodium (Na+): 1.17 g/l to 4.39 g/l

potassium (K+): 0.750 g/l to 2.61 g/l

creatinine (C4H7N3O): 0.670 g/l to 2.15 g/l

inorganic sulfur (S): 0.163 to 1.80 g/l

Lesser amounts of other ions and compounds are present, including hippuric acid, phosphorus, citric acid, glucuronic acid, ammonia, uric acid, and many others. Total solids in urine add up to around 59 grams per person.

The money in this on a large scale waste water is behind the scenes but in the works. The major setback is pharmaceuticals in waste and there really is no way around this factor that I know of. The waste water treatment plants pay around $200-$300 to remove 1 pound of nitrogen from water. Find a way to convert that to safe and pathogen free urea and phosphorus for farm fields and offset that cost at the same time, and it may be viable. One more reason to grow your own food with your own piss if you prefer.
Personally I'd rather piss on a tree but I don't think I'm cool with the whole neighborhood pissing on it.

i don't want to grow anything that closely resembles 'Uruguay piss'. the legal government grown weed they sell super cheap is said to smell and taste like piss, people there think it's because they use piss as a nutrient.

i doubt that has any validity, i think it's because they're using a crappy cultivar that most of us would discard of after one grow, or not bother with in the first place. but it would be interesting if it's true, the smell and taste is because of urine being used on the plants.

i don't suppose you've grown clones of any girl that came out pissy? would be interesting to see if done in proper balanced soil if it would change much.
a gentleman i was working with several years ago grew a strain that smelled and tasted like cat piss. it was really horrible. he said it didn't matter how it was grown, that's how it smelled. just it's terpine profile. the effects of it made up for the taste in a big way tho. three plus hours of heart racing happy time. perma grins for everyone.

i don't know, but it seems like it would take a huge amount of piss in the soil for it to make a plant smell and taste like it.

i wonder if the salts and sulfur and other non organic elements in urine would do much harm to living soils microbiology? that might make a plant take in the nutrients from the urine more directly, with out the 'cushion' of being feed thru mycorrhizae.

No, they don't. Keep in mind that our urine is still very much a part of the natural cycle. There's some really good stuff in it.

There's a fellow... I think he's at Berkeley, doing research specifically on pharmaceutical remediation using compost. Let me see if I can find the article.

Folks in Iceland and other Nordic nations are already doing it, too. I'm assuming you're familiar with the tomato+urine+wood ashes study out of Iceland, yes? Ok, let me see if I can find that remediation study article. Gah. No luck! It was a few weeks ago but I know I read it this year.

if it's zero ppm doesn't matter what was removed or what it's source was, it's purified water. pretty sure that's what astronauts are supposed to get.
i know i've read about an incident when their was a problem with the water filtration system and some aboard got sick.
i don't recall if that was non-fiction or fiction though.

Can I use My Urine as a Fertilizer?

Sure you can. In fact Sweden has tested a full scale urine ‘recycling’ program. Among their findings they have discovered that urine is a complete fertilizer for farm use, lowers the environmental impact of wastewater, improves recirculation of the 3 main nutrients, and that the hygienic risks are negligible if handled properly. Nature has been making use of urine for centuries before humans had even mastered the art of agriculture. Animal wastes contain nutrients that plants needs, and in return they provide us with nutrients we need. It is a circle that has been broken only in recent years, but before you go using your pots as a urinal you will need to be aware of how to use your urine. DO NOT PEE DIRECTLY ON OR AROUND YOUR PLANTS. You will burn them. The following will detail everything that you need to know to be successful.

Use in Soil
Pure concentrated urine will burn your plants; it must first be diluted with water. Typically a ratio of 1 part urine to 10 parts water is effective. Some have gotten away with a slightly higher ratio on unusually hungry girls. It is recommended that you do not exceed 1:10, even though a nutrient burn with urine is rare, the smell can be unpleasant, and salts will build quickly, at higher concentrations. For younger plants start with a ratio of 1:20-1:30 and work your way up. As always do not fertilize germinating seedlings. Wait until the cotyledons (little round leaves) have fallen off before beginning any fertilizer regiment. Also it is not needed every water, every other or every third is sufficient. Let your plant do the talking, if she is a nice dark green then lay off a little, use a weaker solution and lower frequency, if she is getting on the yellow side then step up the strength a bit. Note: Urine can have a high salt content, depending upon your diet. I recommend that when you water with plain water, you allow some run off (approximately 1/8-1/4 volume of your pot) and toss it, this should rid your soil of excess salts.

Use in Hydro
About 8 ounces (1cup) for every 3 gall or reservoir water has been effective (thanks foto) but you should adjust according to your conditions, plant needs, and smell issues. The nitrogen in urine (ammonia and urea) must first be consumed by bacteria as food. The bacteria then store the nitrogen in the bacterial protoplasm. As the Bacteria die, they liberate the stored nitrogen as nitrate, sort of like a time release capsule, to be taken up by the plants. In soil this is no problem but in hydro setups there may not be enough bacteria culture to breakdown the urea and ammonia. Therefore it will be a good idea to drip your Res water through a porous material that can support a bacteria culture such as lava rocks, ceramic bio filter material, foam, sponge. It is up to you; it does not need to be fancy just able to support beneficial bacteria. This step may not be required if your root mass is large enough or if you have a trickle system through a porous medium like rockwool or coco. To get a good start on your bacteria culture you can get some bio-filter booster liquid from any aquarium shop. This liquid contains "good" bacteria that will help you develop a thriving population use as directed (usually a few drops per gal.)

Human urine is a great source of auxin, in fact one of the most potent auxins can be found in human urine; indol-3-acetic acid or IAA. Among many things auxin is known to stimulate flower growth, promote ethylene production, and stimulate root growth.

I have gone though an entire grow using urine without any deficiencies, but many feel that during flowering your phosphorus levels are too low. If you desire, a bloom fertilizer may be used in tandem during the flowering phase.
A tea made with the Russian comphry plant (3.6-1-10.6) is an excellent organic bloom fertilizer for those of us who do not wish to use chemicals at any step. Also a tea of bone meal, or bone meal in your soil mix is probably the best way to add Phosphorus.

In addition I would, and have, cut back on the amout of urine used in the flower period (both frequency and consentration). There is some evidence that Nitrogen in excess will inhibit flower growth, and increase your 12/12 time.

Your body can only absorb about 10-15% of a multivitamin/mineral pill the rest is flushed out with your urine. Taking a multivitamin/mineral about 3 hours before your urine collection can give you many vital micro nutrients.

A balanced and healthy diet means balanced and healthy urine. Keep fit and eat well and you should have nutrient rich urine and happy plants.

PH
The PH value for human urine can range anywhere from 5 and 8.5 but most often is found between 5.5 and 7.5 in healthy individuals with a balanced diet. A value of 6 is average. High protein diets can lower PH (more acidic) and Vegetarian diets raise PH values (more alkaline). Urinary infection will increase PH value. Test your PH and lower it (coffee, lemon juice, or vinegar are great organic PH downs) if any higher that 6, especially if in a hydro system, or increase your protein consumption. If the soil you are using is fairly acidic, like peat moss you will want to make sure you are not dropping it too low with acidic urine; dolomite lime can help you buffer this up, or increase your vegetable intake and lower your protein.

Pro's

It Works
Tried and true. In my (and a few others) opinion it works as good as commercial fertilizers when used properly. A side by side clone to clone test has not yet been done (to my knowledge), but there is no question that urine produces healthy, frosty, dank nugs, as good as anything out there.

Cheap
You can't beat free can you? Not likely. Weather you are growing for pleasure or profit saving money is something that I think we all desire. If you have no problem with spending the money, then go right ahead. Call it ghetto if you want, I call it natures gift, and I intend to make the best of it.

Available
It’s like fertilizer on tap. No hasty visits to the hydro/garden shop. No “I’ll have to do without for a while”. It’s always there when you need it.

Environmentally friendly
Many of us would like to preserve the earth. Well organic fertilizers are the way to go if this is part of your ethos. Chemical fertilizers are produced from petroleum products, natural gas, and coal. Minerals are made more soluble with acids. After the compounds are used by the plant the contaminants left over in the soil can become poisonous and over time can leave the land depleted and ‘dead’. Using organic fertilizers closes a cycle of life that has existed for millennia. We feed the plants and they feed us, much like the oxygen and carbon dioxide cycle.

Compost
Urine in your compost pile is probably the best way to get extra Nitrogen into your mix.

Con's

Salt content
Human urine will contain various salts. Depending on diet your urine can contain up a max of 2.2% salt, this is because the human kidney cannot concentrate salts to greater than 2.2%. On average salt content will be about 30g/L Total dissolved solids constitute about 5% of urine volume. As previously stated it will be to your benefit to allow some run off when watering and toss it, this will rid your soil of excess salts.

Infections and parasites
Hygienic risks are negligible, unless the urine comes in contact with pathogens after leaving the body. The urine of a healthy person is sterile in the bladder. If you have a urinary tract, or kidney infection your urine will contain bacteria that can infect others. It is quite impossible for the infection to be passed through the plant, bud or smoke. If you are sick the majority of pathogens that can transmit disease will die within 24 hours of leaving the body. Infections will increase both your salt content and PH values, and can contain bacteria that consume nitrates.

Imprecise
Urine fertilizing is not an exact science. Exact nutrient levels and concentrations cannot be accurately established without the proper equipment. Notwithstanding some trial and error is necessary in every fertilizer regiment. Certain strains can have differing tolerances, different growing conditions and methods vary in their ability to deliver nutrients reliably.
