Uric Acid-Urea is a powerful fertilizer. The reason it turns yellow where a dog pees is the concentration is too strong. Urine needs to be diluted 10 to 1 with water. Urine is 17% nitrogen on average. NPK is fairly stable in Urine.
We have done the research and in the Gardening Forums. Pour the urine in a 25 gallon trailer sprayer, add water accordingly and apply using a drip boom. I fertilized a sloped area of grass that has always been poor and now it is dark green and growing better than ever. In previous yrs I have applied 10-10-10 will little effect.
Yes I have applied to garden areas also. Wife and I are both Master Gardeners and grow extensive gardens.
OK. I’ll take your word for it.
I am a retired gardener. I attended some Master Gardener courses, but not enough to get the designation.
I did learn a lot about composting.
