No one has ever been willing to talk about microbe habitat at any level, even when they are trying to sell microbes..
Axe, blanket statements such as that one are not accurate or helpful. Maybe some people don't talk about how important microbial habitat is, but not those who know what the are talking about. There is an abundance of people working with soil inoculates who explain that adding good soil microbiology is part of a systems approach which includes inputs of organic matter, reducing the use of products with negative effects on beneficial microbes, and good cultural practices.
The nation that destroys its soil destroys itself.
