Colloidal silver as a soil ammendment

Recently watched a video on making colloidal silver and it was mentioned to use colloidal silver on the soil. As it is an antifungal, would you want to keep it away from your soil?

Sometimes when growing microgreens or sprouts a little mold might show up and I usually hit it with diluted grapefruit seed extract. Might it be good in those applications?

Does it then also make sense to keep it from your compost pile?

I wouldn't use it.

I have heard of it being used as an antibiotic, antifungal, and antiseptic spray, as well as being added to the water of people's livestock, I believe as a worming agent.

I think the method of action is metal toxicity. Colloidal silver is (please correct me if I'm wrong) a suspension of monomolecular silver in water. It is thusly made more bioavailable, and so it is easier to get silver poisoning than from other forms.

I know that some areas of botany use colloidal silver to stimulate seed production in unfertilised female plants, resulting in feminised seeds, but that is only a niche application.

I would definitely use it! It’s helped me fight root rot in my Ashwaganda plant. I use a paper filter to filter out my colloidal silver when I make it at home and conpost the paper with the remainder silver particulates and my compost is healthier than ever. It’s one of those things you just gotta try and see and never go overboard on.
