There are quite a few nitrogens in humic acid which might account partly for the fertility it imbues but to me the structure of the molecule has always made me think of a soil hormone, of something with a messenger function.

In soil science, humus refers to any organic matter that has
reached a point of stability, where it will break down no further
and might, if conditions do not change, remain as it is for
centuries, if not millennia.

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.

Cheers,
Dieter
