Quick answers
Where should I start with Soil microbes?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Soil microbes?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Beneficial allies before English norms look universal.
Are the scores a ranking of Soil microbes?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Soil microbes to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Aggregates create anaerobic pockets beside oxygenated films. That architecture is why one gram is a city.
Winogradsky columns in classrooms show coloured layers of metabolism. They are teaching theatres, not pathogen kits.
Traits
Aggregate cities
Pores hold water films and air.
Mycorrhizal default
Most land plants quietly pay fungi for phosphorus.
Chemical library
Actinomycetes gave clinics streptomycin. History, not a DIY lab.
Protozoan grazers
Amoebae eat bacteria and release plant-available nutrients.
Not a germ poster
Pathogens are a thin slice. Cycles are the main plot.
Once you see soil as alive, bleach-the-garden advice sounds like deleting a library.

Gut microbiome
A diverse intestinal community fed by fibre — not a single ideal species list and not a wellness shop.
Familiarity 88Probiotics
Live microbes in food or capsules — strain-specific guests, not a whole microbiome and not medical advice.
Familiarity 90Fermentation
Microbes turning food into kimchi, doenjang, yoghurt and other living crafts — chemistry plus culture.
Familiarity 85Skin microbiome
A site-specific living film — oily, moist and dry neighbourhoods, not a sterile wrapper.
Familiarity 62Nitrogen cycle
How microbes move nitrogen between air, soil, water and food — plus the industrial shortcut that feeds billions.
