Pretty much a surfactant, right? But the TEA is considered dangerous to aquatic species which I take as a sign it ain't healthy for the microbes
Do you worry about sm 90 harming your microlife? I've heard it discussed as killing bugs and anything smaller
No I don't worry about that. From MM I know it's not good to add it to compost tea so I do not use it in compost tea. I also know too much in soil is a bad thing, but at the rates I use I feel safe. You know strong fertilizers affect microbe numbers in compost tea as well, but I still feed my plants. I see humic acid in thïs light.
I agree that our compost most likely has humic acid or at least should have, but how can you tell? IDK. I know my plants show improvements when I use humic acid in small amounts, so that's what I do....scrappy
How many things are called SM-90?
It does get confusing, I think there is some hydro slop called the same name. The product I use is from kis compost teas, and is a black powder. I would send a link but my computer is being bitchy today....scrappy

Microbeman brought this information forward a couple of years back. One of the best explanations on the 'how & why' on humus.
Good read!

KIS sells the powdered seaweed extract from Acadian Seaplants, Ltd. (ASL) and between the Maxicrop product and ASL, this one is far superior.
Not to mention 40% less......
