Very nice and maticulate piece! Good knowledge, and a respectable projection of your message. I believe, that there is no disputing the historical usage of human urine in agriculture. For those who smell "ammonia" in their urine or any other urine, its actually high concentrations of bonded Nitrogen. This Nitrogen that is so beloved by urine fertilization users is very different in its molecular structure than the Nitrogen that is found in commercial grade fertilizers,partialy. The nitrogen molecules that are found in urine are very distinct and uniform in regards to urine. Human Urine Nitrogen in a molecular structure is a triple covalent bond. It shares three pairs on electrons within its bond. Scientifically, it is the least used by cannabis, as well as, the hardest to intake. That is scientific fact, not heresay.


The nitrogen found in commercial grade fertilizers has a very distinct and uniform molecular structure as well. This Nitrogen is( generally speaking, nitrogen does vary in the commercial fertilizers market) consists of two particles. 1. Nitrate Nitrogen 2. Ammoniacal Nitrogen. Nitrate nitrogen comes first: it is soluble in water and moves through the soil easily. It is the form that is most easily taken up by plants, is available whether the temperature is high or low, but, because it is soluble, it is the form most easily washed out of the soil and lost. This is not disputable. It is scientific fact. This is the first choice of cannabis for sources of Nitrogen just based on its ease of capillary, as well as its availability.

2.Ammoniacal nitrogen is also water soluble, and is partially taken up directly by the plant. But most needs to be converted to the nitrate form by microorganisms in the soil before it gets into the plant. These microorganisms work better in warm temperatures than cold, so the ammoniacal nitrogen may not be as available in the early spring or the late fall. As ammoniacal nitrogen is converted to nitrate it acidifies the soil. The reasons for the application of this form of Nitrogen is actually economically statued. This Nitrogen closely resembles human urine nitrogens molecular structure. The other reason for its application in commercial grade fertilizer is because of Ammonia's ability to preserve nitrogen molecules because of their scientific need to form molecular bonds through the path of least resistance. That path is through Nitrogen. Once bonded, Nitrogen will last alot longer, especially considering the elements in which the nitrogen is in. Studies have shown, especially the ones done by Dr. Greg Honsworth from Cambridge University, that even when plants are showing significant signs of Nitrogen deficit, there is usually a OVERABUNDANCE of Ammoniacal Nitrogen still available in the plants medium. Plants are very very reluctant to utilize this form of Nitrogen, even when they absolutely need to. Considering a plants basic instict of Survival...this sincerly goes to show how hard up a plant is to utilize this form of Nitrogen. Also, this form of nitrogen is a "Timed Release" Nitrogen. Due to the need to be converted into Nitrate Nitrogen.

So, scientifically speaking, yes humine urine does provide limited benefits of Nitrogen. The P-K in human urine is in super small amounts (ppm). Moreso, the forms that they are found in Human Urine are completely useless to Cannabis.

I wish to say that, to those who know me on this site, know my credentials. I am a retired Botanist( Plant Biology). I will never claim to know it all, or have all the right awnsers. I have been wrong before, and will be again. I believe everyone has a right to interprut what they wish with their own wisdoms. Moreso, everyone has a right to an opinion. In my times, I have found that Plant Biology is the polar opposite of Plant Cultivation ( agriculture). Though they share some basic sciences, they are on opposite ends of the spectrum. Not all facts of Botany, are applicable to agriculture. In the end, what works for some, may not work for others.

However, although there have been great results using human urine as a fertilizer, science says that its not all that great. Moreso, in all of these studies, genetics was never a factor for some reason. They seemed to be awashed at the results of human urine without any consideration into genetics. I believe that is where the theory of human urine fertilization begins to show its flaws. Even with proven growth with its application, NONE are comparable to commercial grade fertilizers ( even though they are petroleum based doesnt make them the devil or not superior). Until there can be regulated and clinical studies to prove one version better than the other, all that can be said from a scientific point of view is " TO EACH THEIR OWN".

I hope you enjoy reading this. This subject has been a fun one to converse about. I am happy to see the level of science applied to cannabis cultivation. Its all a learning curve that does not stop in any of our lifetimes. Way to go Roll it up! I can only wish to see more good stuff like this in the future. ROCK ON!!! This Bong is for you!

Peace, Love and Happiness

I have to admit that my botanical knowledge is extremely limited ( at least as far as book learning ), and my only claim to wisdom comes from having been raised on organically grown since before there was such a term, and the passed down knowledge from multiple generations of gardeners. So I must bow to your obvious superior knowledge. However, having lived in agricultural communties most of my life, I also am aware of the trade off farmers must make to grow crops using commercial ferts ( petroleum based ) With your knowledge I'm sure you are aware that over time petro based ferts ( regardless of potential gains ) eventually will wipe out all the existing microorganisms, build up toxic levels of salts, and eventually can completely kill the soil. Also, having lived my whole life on organically grown produce ( and I'm really not a conspiracy theorist ) I have my concerns as to the possible connections between petro chemicals, and things like the escalating number of children born with autism, escalating numbers of bizarre cancers, obesity, lack of disease resistance, etc., etc., etc.

My entire family have lived lives blessed with unusually robust good health. With the exception of physical damage due to activities or accidents, my family has very little use for doctors. Strep, flu viruses, and other infectious maladies seem to be unable to get more than a passing grip on us and we recover extremely quickly.

I too am enjoying this conversation very much, and am curious to know what you meant about concerns about genetics. Could you be more specific on that issue? I would am considering doing an actual side by side comparison, and would appreciate your collaboration on this subject.
