On my research on sustainable agriculture I found this great book by Annie Francé-Harrar, called „die letzte Chance für eine Zukunft ohne Not“ („the last chance for a future without adversity (?Right word?)“)
(in one sentence) This book is about the importance of humus for mankind – 700 pages long. It is written so beautifully and understandable, even though it is quite scientific. In my opinion it is definitly worth reading – even one or two chapters…
She wrote it in 1957!!! Amazing!!!
At the end of the book Annie F-H suggests to produce humus by collecting and transforming human feaces. I know that in the former DDR they put human feaces directly on the fields with the result that many people got very unpleasent worms in their guts. (@Julian: not the tiny, cute ones you see just under your microscope…).
From the present point of view: would it make sence to produce humus by using human feaces?
