Oh yes,
but i bottle it up until i have 2l of it, by that time its decomposing itself.
Its the urea that decomposes to ammonia, promoting the decomposition of the organic matter and adding nitrogen,
there is some debate as to wether female urine should be used. This is due to the hormone content. I doubt that natural hormone content is likely to be detrimental, but their are real environmental concerns over synthetic hormones, as would be present if the female in question used hormonal contraception (the pill). That said, ive seen no data on any effects relating to land based organisms or the hormones persistance in such an environment, most concerns are with the effects of these synthetic estrogens in the aquatic environment (some rather strange effects have been noted on the sexual characteristics of fish, and i dont mean whether other fish fancy them or not)
I remember that zoe, my springer spaniel bitch,in common with most female animals, would cause great damage if allowed to 'go' on the lawn. So, from that view point it would be an advantage, as it has a strong effect on the vegetation.
Personally, i doubt that female urine would have any detrimental effect in this context, and male urine is fine, so, let yourself go!
on a slightly more distastful note, i am curious as to how effective this actually is, and intend to test the theory out in laboratory conditions in the future (when i find somewhere to do the experiment that no one will object to)
