Human Urine

Soiled Crops
Every day I let my dog out to the backyard. He does an entire lap around the yard while marking his territory. One time I noticed that while doing his little routine, he would always piss on this particular plant like if it were a fire hydrant or something. At that time I thought he would eventually kill the plant, I mean its piss he is pouring on it right? However, to my amazement the plant survived after two full weeks of this special treatment. Not only did it survive, it actually flourished more than some of the other plants surrounding it. Since my dogs urine had such effects on the plant, I wondered if my own would provide the same results. But instead of acting like a dog and soiling my own yard, I will explore the pros and cons of using human urine as a fertilizer.
The first step in finding whether human urine can be used, as a fertilizer is understanding how we produce urine itself. In humans, soluble wastes are excreted primarily by the urinary system as urine. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other organic compounds. This mixture of substances then flows from the kidney through the ureter, bladder, and finally the urethra before passing from the body (Karak and Bhattacharyya 401). Now that we have a concept of how urine is made, our next step in determining whether urine can be used is as a fertilizer is learning what urine is made of. To start, urine is principally water. It also contains an assortment of inorganic salts and organic compounds, including proteins and hormones. Though urine varies in appearance, normal urine is a transparent solution ranging from colorless to amber but is usually a pale yellow. Normal human urine is odorless, but if left in the open for some time it changes to a distinct ammonia smell. Some of the main components of urine are ions like sodium,

    The act of voiding the urinary bladder is micturition. Normal urine color is pale to a dark yellow. The odor of urine is usually described as a “nutty” smell although different foods can have an impact on what urine can smell like. If urine smells sweet that is a possible sign of diabetes. The urine contains 95% water and 5% solutes like electrolytes (sodium, potassium, chloride, and other ions), urea, creatinine, uric acid and metabolic end products…

    The use of soluble nitrogenous fertilizers in conventional farming, impacts the nutritional value of the food grown (Bacchus 2012, p.25). It leads to an increase in plant growth and development however a decreased allocation of resources towards the production of secondary metabolites (Mitchell & Chassy 2011). These include DNA, RNA, chlorophyll, amino acids and starch and phytochemicals of caffeine, isoflavonoids and phenolic antioxidants (Mitchell & Chassy 2011).…

    The short video shares a lot of information and views about the public relations industry. The opinion that is expressed is that the public relations industry manipulates the public opinion and the well-being of the general population. I agree with this entirely. Advertising and marketing is a form of propaganda, it has become a part of our culture and we don’t even notice it. Many Americans still believe that we are not influenced by it, but we are every day. Public relations firms go out of their way to keep their campaigns hidden from the public they seek to influence. I was shocked to hear that the news sometimes may not even be real news. I watch the news and love hearing all the new stories that are going on, and to hear that the PR may be behind as much as 50% of it with pre-made pre-packaged stories is pretty disappointing.…

This disorder is chronic and could possibly causes lots of pain, inflammation and because of these things it could cause your bladder to have a limit on how urine it could hold at a time. Which in result you have the urge to empty your bladder often, your physician will be able to diagnose this by doing a urinary culture, cystoscope or even a biopsy. When the doctor preforms a cystoscope he or she will use the instrument that is about the size of a straw to look inside your bladder. At that time the doctor will be able to fill the bladder with liquid or gas to distend the bladder. To prepare for this type of test the patient must get a form of medicine from the anesthesiologist so that area can numb and so the patient won’t feel any pain.…

    Climate change, environmental degradation and unsustainable consumption of resources are increasingly putting a strain on the Earth’s natural wealth. More sustainable sanitation behaviour such as using wholly UDDT (urine diverting dry toilets) can help alleviate the strain on water resources. Urine could be used as a fertilizer as it contains nitrogen and phosphorus. Furthermore, with urine as a fertilizer, it would now be free, accessible to all and decrease our need to mine phosphate. This paper explores the perceptions and knowledge of farmers in the eThekwini municipality about urine and its use in agriculture. It seeks to understand if this practice would socially acceptable in order to contribute to the debate of food security. To investigate the attitudes towards urine, interviews were conducted with farmers who consult with the UmBumbulu Agri-Hub and at the Newlands Mashu Permaculture Learning Centre (NMPLC). These interviews were done in order to find out their views of urine and its possibility on integrating ecological sanitation, more specifically urine reuse in their programmes. Preliminary results illustrate that individuals’ self-perception, that of others and non-motivational factors such as smell and lack of training remain as barriers to usage as well as lack of knowledge about its potential for fertilizing capabilities. In Zulu culture urine seems to be utilised in various ways and is deemed acceptable for medicinal or spiritual purposes. Nonetheless, there seems to be a negative perception of urine amongst most respondents. Even so, many farmers expressed curiosity towards the use of urine in agriculture.

    Chlorination is the process of making drinking water suitable for consumption. Chlorinated drinking water is important in obtaining sanitary drinking water. Because water is a beneficial part of life, it is important to evaluate both the benefits and risk of having chlorine in drinking water. The EPA regulates the amount of chlorine in water with an acceptable daily intake of 4 parts per million or 4 mg/L. Epidemiologists have linked an association of cancer to chlorinated drinking water. These hypotheses were tested in both rats, mice, and other rodents and in humans. Many scientist notes in rats, high concentration of chlorinated drinking water corresponded with DNA and chromosomal alterations resulting in tumor formation. In humans, acute…

    5. The urinary bladder is a hollow, expandable, muscular organ located in the pelvic girdle. Although the shape of the bladder is spherical, its shape is altered by the pressures of surrounding organs. When it is empty, the inner walls of the bladder form folds. But as the bladder fills with urine, the walls become smoother. The internal floor of the bladder includes a triangular area called the trigone. The wall of the bladder consists of four bundles of smooth muscle fibers. These muscle fibers, interlaced, form the detrusor muscle and comprise what is called the internal urethral sphincter.…
