Re: [SuSanA Forum] Composting toilets do not produce compost - true or false? And is "composting toilet" a misnomer? (Composting toilets, Arborloos)

"Urine has a fertilizer value of N/P/K 18:2:5"

From here:

I don't know where Elizabeth got her figures from, but they (or your interpretation of them) are wildly different to anything I've ever read. Given that NPK amounts are usually expressed as a ratio, I'm not even sure what a percentage could mean.

If you want to discuss any of your other points, including the soil science of British allotments, I'm happy to do so on a different thread.
