Liquid oxygen

Even better... https://pubmed.ncbi.nlm.nih.gov/29356911/

I kinda lol at the price of that stuff, btw. I can buy 500kg each of dolomitic lime and gypsum for that price.

But here's a little "overview"... https://www.cuteness.com/article/increase-dissolved-oxygen-water

That's entirely speculative, btw.

So essentially... You kinda pump oxygen into disturbed water (like say, with ultrasonics, any way of moving it, basically). I'd run a current through that too. Tada, dissolved oxygen. Nice mention, thanks. Coz I just figured that out. Dissolved oxygen isn't hydrogen peroxide, though, adding hydrogen peroxide and using something similar to what I describe (though perhaps also with some electrolyes) might make production simpler. You know, if you're ghetto.

If your soil is dense and packed tight don't worry about liquid supplements, focus on creating a better root environment. Roots are going to grow better in loose soil with good drainage than clay like mud. When you repot your plant work in a healthy amount of perlite and maybe some sand and see if it's more crumbly. If not source better dirt.

Oh Buddhi, Your really wearing these questions out aint you haha. Yes if your groing in soil adding oxygen to the root zone will benefit your plants. Though the best way to give your plant oxygen to the roots is to just start with air pots :) They are really really good at keeping roots airated and growing healthy also they look pretty cool too :) 👊 I and if that Sir guy pops up he has beef with me for no reason so just ignore him :)
