If dog urine kills plants, why would so many dogs raise their legs and pee at the plants around them? Will the plants be miserable? I
have many theories about the toxicity of dog urine to plants. One popular theory is that high urea levels in the urine cause it. Some people say that aciduria can burn plants, but is this true? Older generations were right to believe that peeing on a tree would burn the roots because the urine was so concentrated. Is it true?
I think it’s actually like my mother pickling cucumbers at home. If the salt is too strong, all the water in the pickled cucumbers will be sucked out. The principle of "burning seedlings" is the same. The soil solution is too concentrated and sucks all the water out of the roots.
Normal dog urine contains 2%-5% solid matter (excluding dogs that drink a lot of water). In other words, there are about 20-50 grams in 1 liter of urine. The concentration of the soil solution in saline-alkali land is about 30g/L, and the results are very clear. Dog urine is equivalent to the harsh environment of a salt-alkali land.
In addition, dog urine will change according to changes in food. Sometimes it is weakly alkaline, which will change the acidity and alkalinity of the soil. This will also affect the survival of plants, especially plants that like acidic soil (such as tea trees).
Of course, dogs will not pee too much. Once or twice won't cause big changes. But if you keep watering in one place for many years, you may be close to death.
This reminds me of when I was a child, there was a small sapling that I watered to death with my urine. I was young and ignorant at that time, so I thought that watering the sapling more would be good for its growth!
