I'm not finding much information on root oxygenation. I'm only finding

keep hunting.

Try looking for root aeration.

A quick update: I have had absolutely no luck at all using "root
aeration" as a search criteria to find any information that sheds light
on the OP's question about oxygen in water.

"Root aeration" search results only show information about getting
oxygen to the roots of plants not "oxygen in water" getting to the roots.

It seems that "root aeration" does not equate to "oxygen saturation in
water". I've decided to become unfixated on the issue as I suspect it's
not important unless I want to go into hydroponics.
