I like the handle. 
Aerobic bacteria and microorganisms are typically better for plants and it smells better. Anaerobic bacteria are responsible for locking up nutrients and a number of plant diseases. She may want to aerate that before applying it to restore the aerobic bacteria with something like this:
You can substitute stuff in and out, and after he says something like that is the end of the Elaine Ingham of “soil food web” recipe, you can stop there. I think the rest is he was just throwing in stuff that was sent to him for free ie product placement. And he is incorrect, when he says it replicates the mycorrhizal fungi. It does not. But it does spread it out so it is applied evenly. Mycorrhizal fungi is great stuff because it attaches to the roots of most plants and gives them up to 20x more surface area, and trades nutrients and water for carbon with the plant. There are 1000s of species of it that have adopted to your area, which is why they encourage grabbing some from a forest or a compost pile with the white threads in it (the white threads are the fungi)
If you are growing grasses, there is a bacteria called azosprillium that fixes nitrogen similar to rhizobia bacteria for legumes.
Anyway, it gives her a rabbit hole to go down, and it isn’t that hard. And that will save her about 30 hours of trying to track down information. There are newer folks that explain the whole thing better but she has the right idea. Feed the microorganisms, because they feed the plant. You just want to encourage the right ones for a healthy soil.
