Talk:Urine to Urea Chemical Proccesing Pathway

The recovery of phosphate is the most important use of urine in my opinion: https://www.earthmagazine.org/article/p-phosphate-could-urine-solve-fertilizer-shortage

Enhancing purity is a wasteful endeavor in this context, just spread it over the field.

I recall reading claims that aging the urine for 6 months is beneficial. Claims that it changes the pH, slow beneficial chemical reactions occur (I don't recall what), and bacteria die out. A suggestion of adding calcium chloride flakes to help the nutrition persist in the soil, to not wash away. I can't find the source of these claims at a glance in my bookmarks, but it was on a forum and I'd hoped to find literature.
