The meaning of the term humus has changed over time. To jumble together
several interpretations of the term in the Wikipedia definition doesn’t do
justice to any of them. Nor does it bring us any closer to what humus
actually is.
In my book, humus is a living organism that is in constant transformation -
that never stops to break down, to transform and to rebuild itself. It is
the dynamic interface between the organic and the non-organic, the place
where life on this planet constantly renews itself.
