Hold your horses?

So I have a few observations that may be useful, as a male human i have been watering trees and plants my whole life with straight urine and not have seen any detrimental affects even after trying to test it out on the same spot repeatedly.

Now on to the horses part, I have a horse and have noticed that where he urinates in the spring after snow melt but before vigorous growing is the only time plants die from to much urine.

My conclusion is that over a gallon can be poured directly around plants that are actively growing but beware around small tender plants.

Hope that helps.

Really! That would be a big help to a lot of people, I think half the turn off is the capture and mixing of the piss.. Yeah looking like small/young plants are more at risk.. My apartment has the same winter piss prob only with a dog piss..

I've never heard that a single application of urine would kill plants (except small new ones, which I learned for myself). You may have to keep trying.

After application of diluted urine I do often see a change in the color of the soil, as if it's a bit too much soluble fertiliser. By the way, the salts from applying soluble fertiliser, including urine, are not necessarily sodium chloride; they are various mineral salts formed by reactions.

I think there are many variables at play and this I believe is certainly something to note. Drinking lots of liquids "dilutes" urine, even though it's still 100% urine. This could be one reason why no symptoms of nitrogen burn have been seen.

Story time: Twenty some odd years ago in another life I lost a job due to a drug test or two of them really. I took the first test and a few days later I got a phone call saying I had to retake the test as the sample was too dilute. I assured the person on the phone that the sample was 100% urine, and they said people who drink a lot of fluids can have dilute urine. whatever. I was required to retake the test, which I failed with honors.

I quite commonly slosh undiluted piss around mature plants that I know are heavy nitrogen feeders like corn, nightshades, cucurbits, and brassicas.  But I don't do it more than once or twice in a growing season, and only when the soil is well wet from rain or irrigation.  Usually I'm walking down the row with a gallon jug, so each plant might get half a cup or so, max.  I guess the main point is I'm not bothering to dilute it ahead of time, which would mean toting five-gallon buckets around even more than I already do!

If the soil is dry, plants are already stressed. Adding urine direct to soil can definitely burn plants - we have had various patches of dead lawn to attest to that. But the critical factor seems to be how dry and stressed the soil and plants are to begin with.

I do dilute it but my formula is two urinations per 2-gallon bucket and fill with rain water or sometimes murky pond water.  It's really helped the plants in my new beds and I add any extra to the compost pile.  I constantly find myself not drinking enough this time of the year as I get busy and don't think about it so my urine isn't as diluted as it should be.  My husband has offered his urine as well but he's on at least eleven different medicines and I'm on none, so I told him to water the mature trees instead.  I also add slugs, grubs and any other pests to the piss bucket to drown.  I figure it helps to eliminate the problem and adds a bit more nutrients to the soil as well.

I have lots of spreading comfrey(not a seeding kind!!!) growing which uses a lot of it. I use the comfrey to mulch and feed the bees and the soil etc. I feed on drip lines more or less, or just throw it diluted on the grass.
In summer when the compost pile is drying, i shade it by plant waste material, dumping urine on top of that woody debris makes it is eaten quicker by fungi i noticed. Spreading it all over makes it that i can say i think i never give toooo much, and it keeps the cats of neighborhood on their toes in my garden.
