Here's what the wikipedia article cited above says about the pH of urine: Quote:
pHThe pH of urine is close to neutral (7) but can normally vary between 4.6 and 8. In persons with hyperuricosuria, acidic urine can contribute to the formation of stones of uric acid in the kidneys, ureters, or bladder.[13] Urine pH can be monitored by a physician[14] or at home.
A diet high in citrus, vegetables, or dairy can increase urine pH (more basic)[dubious – discuss]. Some drugs also can increase urine pH, including acetazolamide, potassium citrate, and sodium bicarbonate.[citation needed]
A diet high in meat can decrease urine pH (more acidic).[citation needed] Cranberries, popularly thought to decrease the pH of urine, have actually been shown not to acidify urine.[15] Drugs that can decrease urine pH include ammonium chloride, chlorothiazide diuretics, and methenamine mandelate.[16][17] Unquote.
Apparently meat eaters, and/or carnivores would be more likely to have acidic urine.
Our soil back home in Northern Michigan are glacial soils and also quite alkaline. I think however in a natural forest there will be a variety of soils, depending on the plant cover. I remember wintergreen berries only grew in the pine straw under pine trees. They require a fairly acid soil.
So if you have a source of pine straw you might use it to acidify some soil for your acid loving plants. Peat moss can also be used, but it is quite expensive now-a-days.
