As an avid gardener and aquarist I felt like a colossal fool after reading on the subject of a near permanent fertilizer, biochar. Used by South Americans for millennia. A lot of people balk at using it because soaking charcoal in urine for a month seems a bit outre to them.

And while reading this I began to kick myself hard for all of the used activated carbon I threw away during the course of my three decades of fish keeping. Used aquarium activated carbon is *perfect* biochar material!

So here is my attempt to leave the world a better place than when I found it. By connecting a former waste stream to something incredibly useful.

Thank you, that is all. https://en.wikipedia.org/wiki/Biochar

Your post on urie uses reminded me of the Sean Connery movie Medicine Man where the shaman applied urine to some bark to make some sort of analgesic for a patient. (I think that was the scene but I couldn't find a reference)

I did find this funny video reference that may bring tears to your eyes:
