Earth worm castings and humic acid

[growsince79]

Someone on another thread said :
"Worm castings DO NOT provide fulvic or humic acids."

Here's the place place to post info on vemicomost and humic acid. I'll start with this.

The influence of humic acids derived from
earthworm-processed organic wastes on plant growth

Here is a study about extracting humic acid from vermicompost. Vermicompost yielded more (5.20%) and higher quality extracted humic acid than farm yard manure. The extracted humic acid was used for soil and foliar application. This clearly shows the presence of humic acid in usable amounts in vermicompost. Unless these guys are full of worm shit.

Uh, no surprise there. Keep trying. Do you know what a scientific analysis is? How it’s presented? That’s what will shut me up You can’t post it because it doesn’t exist. Do you even know what the source is for the two acids? I’ll bet you don’t.

Please educate us all. Every thing I read says ewc contains humic acid. If you want to explain how everyone is wrong, I'm all ears. Learning is what this thread is all about.

Humic Acids Isolated from Earthworm Compost Enhance Root Elongation, Lateral Root Emergence, and Plasma Membrane H+-ATPase Activity in Maize Roots

Earthworms (Eisenia foetida) produce humic substances that can influence plant growth by mechanisms that are not yet clear. In this work, we investigated the effects of humic acids (HAs) isolated from cattle manure earthworm compost on the earliest stages ...
