Put up a sign detailing how you use humanure and compost your own, how you haven't flushed poop since 2016, and how you are using urine to spray as an organic pesticide. Leave a couple two litre bottles of "urine" looking liquid out and label it as organic spray. Just use water, a drop of dish soap and some food colouring though, you don't want to risk being fined for leaving hazardous waste around. It just needs to look like pee. Have a plastic container with your compost in it.

Humanure is a real thing. Even the people who use it, and who actually compost it properly are divided on using it on food crops. I mean, if you don't have hep c, you're not going to infect yourself with hep c by coming into contact with your own blood but someone else, won't know what diseases you have. Same for your poop. You can compost it all you want, if you don't have parasites then your poop, and your humanure won't have them either. But other microbes etc can grow in it if you don't compost it hot enough to kill them and turn that poop into something more like milorganite where people are less grossed out about using it... But still likely won't want it on their food plots.

So probably don't actually compost your own poop for this, just make people think you do.

Oh, pee does actually have value too in the composting world, so feel free to add your piss discs to your compost piles too. Just make sure the compost gets hot enough to finish before you use it and also water it too so it doesn't reek.

But yeah, be the weirdo with the garden that grows from poop and no one is picking your tomatoes after that, unless they can't read.
