Undiluted pee has a very high nitrogen content and occasionally a high salt content. The high nitrogen content can therefore literally “the plant it comes into contact with is burned. Your dog’s poop causes your lawn to turn brown for this reason.
However, urine that has been diluted with water is more effective than any chemical fertilizer. The nutrients nitrogen, potassium, and phosphate, which are all necessary for thriving plants, are abundant in human urine. The word “chemical” is listed under the components on a bag of chemical fertilizer “urea, which, you got it, is found in urine.
Further from the ABC article mentioned earlier
“Researchers from the University of Kuopio in Finland, led by Surendra K. Pradhan, K. Holopainen, and Helvi Heinonen-Tanski, discovered that wood ash and human urine are just as effective as more expensive mineral fertilizers while causing less environmental harm. Nitrogen, phosphorus, potassium, calcium, and magnesium are all abundant in the mixture.
“In a series of precisely planned laboratory tests, the researchers successfully grew a healthy crop of tomatoes. In a greenhouse, the plants were raised in four distinct methods. Some plants got no fertilizer, some got commercial fertilizer, some got only pee, and some got both human urine and birch ash that had been taken from the furnace in one of the participants’ homes.
“The performance of the plants during the growing period was similar between those that received commercial fertilizer and those that received pee and ash, significantly better than those that received only urine, and four times better than the unfertilized plants.
According to the study, urine was gathered from a number of eco-toilets in private houses and kept in storage for around six months (at 45 degrees F) while its “microbiological qualities” were examined. No dangerous chemicals were discovered.
Okay, but you may believe that peeing on your plants is “yucky. Perhaps it is, but let’s consider the wider picture: in the developing world, where chemical fertilizers are failing terribly and destroying already damaged, eroding soil, this may help to support successful agriculture. They could occasionally be in short supply due to economic conditions or political turmoil.
Does urine affect hydrangeas’ color?
You claim that you want your hydrangeas to be pink or depressed? The pH of your soil and the variety of hydrangea you have are both important factors in success.
Some varieties of hydrangeas never change hue. The blossoms on a white “Annabelle” will always be white and fade to green. Limelight will always have green leaves that turn white and eventually pink, and Hydrangea paniculata cultivars like the traditional Pee Gee, Tardiva, and Little Lamb will always have white flowers that turn pink with age. These kinds cannot be made to turn blue in any manner.
The majority of hydrangeas with mop heads (H. macrophylla) and lace caps (H. serrata or H. macrophylla normalis) can be dyed pink or blue. The ease or difficulty of this color change will depend on how acidic or alkaline your soil is.
Hydrangeas turn blue due to aluminum in the soil, although this element is only absorbed by the plant in acidic soils. So you need acidic soil if you want blue hydrangeas. The earth in some areas of the nation is either inherently acidic or is perpetually kept that way by acid rain. This is the reason hydrangeas on Cape Cod turn blue if the gardener does nothing.
On Cape Cod, we don’t have to put much effort into maintaining blue hydrangeas unless irrigation (municipal water), lime from the lawn, or nearby concrete are raising the pH of the soil.
You must add an amendment to the soil surrounding your plants to make it acidic if the local conditions favor alkaline soil and you want your hydrangeas to be blue. Aluminum sulfate is the substance offered most frequently for this function, however sulfur can also be utilized. Whichever option you select, make sure to use the product as directed. Your plants can suffer from too much.
You must apply lime and/or wood ashes around your plants if your soil is acidic and you want your hydrangeas to be pink. To keep the soil alkaline in some regions, it would be necessary to apply a significant amount of lime twice a year.
The change in bloom color won’t happen instantly in any scenario. You might have to wait until the following summer to see pink petals if your flowers are already blue.
Numerous mop-head hydrangeas begin as white or green and then change to pink or blue. Since this is a natural occurrence, there is no need to amend the soil; simply sit back and take in the show.
Is it possible to get a hydrangea with pink and blue flowers? Absolutely. Simply divide the area around your shrubs into four equal portions, and amend the soil in two of the sections that are opposite each other to generate alkaline circumstances, and in the other two to create acidic conditions. So that you don’t alter the areas and cancel out the blue or pink effects, make sure to make a note of which region is which.
Finally, heredity plays a role in the color that hydrangeas display. A ‘Nikko Blue’ Hydrangea will never be dark purple; instead, it will always be light blue or light pink. Most of the time, you can alter a color but not its hue’s intensity.
How frequently should pee be used to irrigate a plant?

Comment: I believe you ought to write about using uric acid as fertilizer in gardens. I’ve been doing it for a while, and the results are excellent. Even an elderly rose shrub that had been dormant for years was revived with it. It is now 6 ft (2 m) tall and in bloom once more.
I began using it after watching a TV story on Africans who collect pee from public restrooms, dilute it, and then irrigate the crops with that instead of purchasing chemical fertilizers from BASF or Monsanto they can’t actually afford!
I merely urinate into my watering can, then fill it up with rainfall. By doing this, I’m preserving drinking water and avoiding fertilizing my gardens with chemicals that will contaminate the water table.
Answer: I have, indeed. However, I must admit that I have been dodging the subject.
Although I am aware of the benefits of having human waste in the garden, the gross element just… overwhelms me. What else can I say than that I’m uncomfortable? I keep lecturing myself that I’m being priggish and that my audience should be informed. I’ve even scheduled writing about it on few occasions, but I always come up with a better idea right before the deadline. Well, there it was on my schedule once more. I’m doing it this time.
In other words, urine is a superb fertilizer. Unquestionably among the greatest.
It is particularly rich in nitrogen, the nutrient that soils are most frequently lacking in, and is readily available for plants to absorb. In reality, the ratio of minerals varies depending on a variety of circumstances, including the “You could estimate an NPK ratio of 11:1:2, or 11 percent nitrogen, 1 percent phosphorus, and 2 percent potassium, for a Westerner with typical dietary habits. That is equivalent to a lot of commercial fertilizers! Additionally, urine is a complete fertilizer since it includes nearly no heavy metals and all the trace elements plants require, including iron, boron, zinc, and others.
On the other hand, because urine contains so many salts (particularly sodium), it is typically advised to dilute it in 10 to 15 parts of water. (For seedlings, use 20 parts.) Additionally, don’t apply it to any one garden area more frequently than once every two to three weeks.
You’ve all seen what excessive salt in dog poop can do to a landscape, right? You wouldn’t want the same issue in your garden, would you?
None will exist if you use it immediately. Except if you have consumed asparagus (more on that here), or if you have a urinary tract infection, fresh pee is practically odorless (in which case, see a doctor). However, if urine is left to rest, bacteria begin to convert the odorless urea into ammonia, which has a stench. Microbes in the soil will stop any stench once it is in the ground (and has been diluted, too).
The high nitrogen content of urine makes it a better choice for your compost bin, where it will hasten decomposition. Even diluting urine before applying it to compost is not required. Send the lads out so they can use it right away!
Utilizing fresh urine is not problematic because urine is regarded as sterile as it leaves the body. That’s a different story when it’s being stored. However, there are benefits and drawbacks to using pee that has been kept. I’ll let you research that on your own, but be aware that even scientific viewpoints might differ greatly.
Can you use urine on edible plants like veggies and herbs? Sure! It is advised not to spray it on the foliage, but rather to the soil at the base of the plants. Additionally, it’s recommended to halt urine fertilization 3 to 4 weeks prior to harvest.
But what if you are taking medicine or are aware that you have a UTI? Again, viewpoints differ. Some specialists advise not to worry because any bacteria or drug residues in the urine will breakdown when they come into contact with the soil, which is after all home to a variety of gregarious microbes. However, if you are taking medicine or are aware that you have a UTI, several authorities advise avoiding using urine in the garden. So, who can you trust?
If you’re on medication or have a UTI, I would personally err on the side of caution in this situation and advise against using pee.
Will I myself use urination in my gardens? No, but at least I have a valid justification now: I appear to be taking a variety of medications as a result of my sputtering old age. However, a few years ago, I could have done it logically… but I never had the courage to. Yes, I admit it: I was held back by the ick factor.
What plants benefit from urine?
The beets Surendra Pradhan and Helvi Heinonen-Tanski raised were exquisitely beautiful: round and hefty, with skin that was a dark crimson, and a flavor that was sweet and subtly earthy, like the dirt from which they were grown. You wouldn’t be aware that the beets were fertilized with human pee until someone told you.
The beets were grown as part of an investigation into environmentally friendly fertilization by Pradhan and Heinonen-Tanski, environmental scientists at the University of Kuopio in Finland. They found that a mixture of urine and wood ash performed just as well as conventional mineral fertilizer for nourishing the root crops.
Heinonen-Tanski, whose research team has previously used pee to raise cucumbers, cabbage, and tomatoes, asserts that using human urine as a fertilizer in place of commercial fertilizer is entirely feasible. According to the researchers, recycling urine as fertilizer might increase food production and sanitization in underdeveloped countries as well as make agricultural and wastewater treatment more sustainable in industrialized nations.
Nitrogen, potassium, and phosphorus, which are essential for plant growth and the major components of most mineral fertilizers, are abundant in urine. Naturally, there is a constant supply of this synthetic plant food: an adult eating a conventional Western diet excretes 500 liters of urine annually, which is enough to fill three standard bathtubs. Heinonen-Tanski also noted that, despite its potential for grossness, urine is mostly sterile when it exits the body. Pee has no health hazards, unlike feces, which can include pathogens like salmonella and E. coli. Astronauts on the International Space Station even drink urine after it has been cleansed.
According to Hkan Jnsson, a researcher at the Swedish University of Agricultural Sciences in Uppsala who was not part in the beet study but has studied urine recycling for more than 15 years, the nutrients in urine are also in just the perfect condition for plants to drink them up. Our digestive system converts nutrients like nitrogen that are present in food into the basic mineral form required by plants, so “we have done half the work,” according to Jnsson.
Pee is already used as fertilizer by a tiny but devoted group of organic gardeners in the U.S. and Europe, and researchers in Scandinavia have implemented trial programs to reuse locally collected urine on small farms. But since executing it would require significantly altering sewage systems in order to collect and convey liquid waste, large-scale farming may never become a practice in industrialized nations.
It would also include replacing standard flush toilets with separating toilets, which separate urine from other waste using a divided bowl and separate set of pipes. According to Jnsson, this element is a barrier because many people don’t want a toilet that looks odd. The system’s acceptance is a major issue, he continues.
Urine from customized toilets in private homes was used for the most recent trial with beets. Heinonen-team Tanski’s grew beets on four different plots, using four different fertilization methods: mineral fertilizer, urine + wood ash, urine alone, and no fertilizer as a control.
Approximately 280 beets were collected after 84 days. The beetroots from the plants fed with urine or urine and ash were discovered to be 10% and 27% larger by mass than those fertilized with mineral fertilizer. The researchers found that all of the beets had equivalent nutrient contents after subjecting some of them to chemical analysis, and a blind taste-testing panel found that their beety tastes were indistinguishable. The Journal of Agricultural and Food Chemistry published the findings in its edition dated February 10.
In a review article published in the January 2010 issue of Sustainability, Heinonen-Tanski argued that recycling pee had additional advantages besides effective fertilizing. She said that the simplified waste stream required less energy for sewage treatment and that the separating toilets that collect urine use less water than flush toilets.
Heinonen-Tanski noted in the report that “Agricultural and health agencies should promote individuals using human urine as a fertilizer, especially in locations where wastewater treatment is unavailable or inadequate.”
Despite his skepticism regarding the possibility of micturition farming on a wide scale, Jnsson’s family does engage in urine fertilization. He and his wife utilize the pee they collect from their separate toilet to feed their garden at their Swedish house. According to Jnsson, one person’s pee can fertilize around one square meter of soil per day, but since his three children left the house, there is less urine to go around.
“He said, “I can only apply very light fertilizer to the lawn, but it’s enough for the flowers and vegetables. I would run out of urine otherwise.”
