Air pump for soil?

Anyone heard of putting an air pump in the bottom of a soil medium system for extra oxygen to the roots. do you think i would help or think it would be a waist of electricity? i know you need a air pump for hydro but i couldnt find any info about air pump usedin soil. stupid question but curious

Good reason why you couldn't find any info, it's just not happening.

There are threads on it, if you want to search.
