There is not a lot of detailed information about the use of urine in corp fertilization as to how much to use. The ratios go from straight, to 1:1, to 1:5. to 1:20. Most of the information that I have read from technical studies were concerns about safety and suggesting that you stop before fruiting, etc. I don't feel that this is an issue for the home grower, if you are not ill. However, the concern that I would have is that nitrogen produces lots of leaves and all leafy vegetables love it like cabbage, kale, spinach, but the over use of nitrogen can cause a plant to produce leaves and few or no fruit, so it is possible to over do it. One unexpected side effect that I have noticed is that we were fertilizing a nopales cactus and it was doing terrifically well, producing new growth and flowers, but it out grew its ability to support itself and a large section broke off because of the weight of the cactus pads to the strength of the supporting stalk. We may have overdone the nitrogen with the urine?
Check the fertilization requirements of the plants that you are concerned about and treat the urine as a nitrogen fertilizer and not as water and follow the recommendations.
