What are you talking about?
Maybe you're confused on soil structure (the combination or arrangement of primary soil particles into secondary units or peds).
Why get all worked up about irrigation? Are you suggesting that all our turf problems can be solved with water applications? Irrigation isn't the end-all-be-all. Don't forget the other factors that your own link listed.

The beneifcial microbes that you keep harping on are ALWAYS
in the environment (read your own link!) They are less active when the turf is sparse and they are more active when the turf is healthy. Research has shown that you cannot add more or make the current ones more active in hopes of relying on them (in whole or in part) to help build your turf stand -- that doesn't work!
Microbes increase in number and function only when things are done to encourage turf growth.
Let's put it this way:
Healthy Turf = Active microbes
Unhealthy Turf = less-active microbes
Cannot have the same level of activity and the same populations of microbes without active turf, even if you add microbes
Microbes respond to their environment. You don't have the same levels and kinds of microbes in a sparse turf as you do in a thick turf. If you try to add microbes or substrates without first improving the turf, the microbes will ramp up until they eat the substrate (or each other), then you will be right back to where you started (I think Sumagreen et al know this and this is why they want you to buy their stuff -- so you'll always be coming back for more).
All the research and university links agree -- conventional methods work, microbial methods do not.
