I quickly found these notes and I am surprised at the content
Hyper-oxygenating water increases nutrient uptake and conversion efficiency which enhances the growth and development of
roots, vegetative and flowering characteristics. For instance, oxygen will oxidise organic phosphate into inorganic phosphate which can then be readily used by plants.
From

"Dissolved oxygen (DO) in irrigation water is often completely neglected. It’s a parameter that is completely ignored and yet it can have a significant impact on plant health,
root development, fertiliser & water uptake as well as yield. Even some of the most advanced farms who pay attention to just about every parameter which influences plant growth and yield completely ignore water DO requirements.
The typical origins of water used on crops is rainwater - high in O2"
"Insufficient water DO can lead to other problems as well.
For instance Nematodes prefer oxygen poor soils and irrigating plants with water poor in DO will allow them to come near the surface where they can easily damage plant roots."
From
manetising irrigation water
". The results indicated that irrigation with magnetised water and then adding fertiliser (MWF) had a positive significant effect on the water
and soil properties, the tuber engineering parameters improved and the potato productivity increased by 40.5% higher than the NM method.
The fertigation unit has to be installed after the magnetic device because the direct magnetisation of the water with the fertilisers contributes to the cracking and increases the solubility of the fertilisers that may lead to the possibility of leaching some of them away from the roots, which implies losing some of them and, therefore, decreasing the effectiveness or fertigation"
