Since urine can have an alkaline or midrange PH, would it enhance the fertilizing effects of urine to add vinegar?  I have a lot of plants that like acidic soil that are well drained and would probably move the salts out the bottom of the pots but from what I understand, the acidity will release more of the nutrients in the soil. I'm thinking piss and vinegar might be a good combination. Also, from what I understand, urine has some minerals in it and I'm wondering if the vinegar would also make them more available to my potted veggies.

urine/vinegar not so sure. I use diluted urine and kelp meal mixed solution. My leafy greens, and tomatoes & peppers love it. Can't complain.

wow, i'm so confused. I thought vinegar as a general herbacide, or I would have tried it. I thought urine, uric acid was acidic, and tended to break down into ammonia, more acidic. I add all the pee i can to my beds but i only produce so much. My soil is frequently 8. p.h., which means almost no available phosphate. I'd love any good ideas, but have probably tried them.

conifers normally have acid mulch, but I suppose you already tried it?

Urine can be acidic or alkaline when it leaves your body, but as it becomes stale the urea converts to ammonia and the pH shoots up to about 9. However, as the ammonia converts to nitrate I understand that the process produces acidity, with the result that some alkalinity in the soil is consumed. So I think adding urine probably has a mild acidifying effect on the soil.

I've just used a few tablespoons of vinegar to 1:10 ratio of urine and water in gallon container. Tested it on a planting pot with potting soil compost mix that had a ph reading of almost 8. I added enough to moisten soil as if watering a tomato plant. I waited 15 minutes for the mix to be soaked up and measured the ph at approximately 6.5.
I will continue to monitor the test pot soil

I don't know the science behind it, but I add a little vinegar to my urine collection jugs, which keeps it from getting the bad smell as it ages. I, then, pour the full jugs around the plants in the garden, and haven't seen any negative effects yet. My soil is alkaline (pH of 8), so I welcome any acidity it may bring to the soil.
