Urine is indeed a nitrogen fertilizer. Urea is the product of protein degradation / recycling. It is also, in its synthetic form, a nitrogen fertilizer used in agriculture. Slurry is nothing more than a mixture of solid and liquid droppings from our farm animals. They end up in the fields ... Excess raises questions, not the principle (because it is the nitrogen of Brazilian soybeans that our animals piss off; the spreading surfaces, which are by far not sufficient to feed these animals, which also eat our cereals, these surfaces "collect" therefore excess; and collect very badly !!!)
From this point of view, the invention of the whole to the sewer was an "opening" of the natural cycles, with a nitrogen leak ... An agronomic disaster. Fortunately, we had to recycle the explosives industries (TNT = Tri-Nitro-Toluene; and who says "nitro" says nitrogen) and another solution was found: synthetic nitrogen fertilizer!
Urine has one drawback, however: its high salt content, which is not present in such large quantities in our vegetables. Salt is added [it is a need in animals, especially mammals, which need it to balance their "internal juice"; oddly enough, they reconstruct the "salt sea" in which life was born 3,4 or 3,7 billion years ago; it is not for nothing that the Tuaregs travel thousands of km in the Sahara for the salt cures of their camels). So the return of all this salt to the fields / gardens is not natural. Fortunately, sodium is a very soluble element, leached by precipitation, in our climates.
A tree will not do anything to him. But beware of your vegetables if you always piss in the same place! I advise against.
A solution, tiring for a Sloth, is to dilute and distribute regularly over a large area.
Cultivating laziness, I observed the cows, found that they diluted nothing at all, but rarely pissed at the same place. I never observed a negative effect on meadows during my lifetime. Just greener rings where they had pissed. I'm inspired by cows! And is aimed at the most voracious vegetables: cucurbits, cabbage, potato ... I also avoid those that I will eat in the following days (salads). A psychological block because urine, except sickness, is sterile!
[Do not apply this reasoning to "feces" - solid droppings, which can peddle disease. Young, our all had ascaris or even tapeworm. I remember the deworming].
