Human urine can work wonders on garden veggies, but it needs to be diluted. And there’s very little smell. Outhouses reek because urine and fecal matter are mixed, resulting in a deafening stench. Similarly, feces have little or no smell when collected properly, separate from urine. I’ve experimented with collecting “humanure” indoors and it had no smell. It composts beautifully (along with the TP) and creates fabulous soil.
We lived off grid for 5 years and did the humanure thing. I wouldn’t put it on my food plants though unless times were desperate. The Humanure Handbook author has used it on his veggie garden for 30 years though.
