Compost English
Browns and greens is gardener slang for carbon and nitrogen. Microbes do the chewing.
Darker cells mean a higher score for this topic on that metric.

Quick facts
A gram of soil can hold 10^8–10^10 cells and thousands of taxaDensity
Most diversity is known as DNA, not as a named isolateUnculturable majority

Bacteria and fungi unlock cellulose and ligninDecomposers
Soil is a factory of cycles, not a synonym for filthNot dirt equals germ
Soil microbes are the hidden workforce of land: decomposers, nitrogen transformers, mycorrhizal fungi and a majority we only meet as DNA.
A teaspoon can hold more taxa than a field guide can name. Most never infect a person.
This atlas treats soil as an ally habitat, not a synonym for filth, and gives no culture or extraction recipes.

Living dirt
English gardening copy discovered soil microbes after it discovered organic. The local truth is older: compost heaps were guilds before they were brands.
Bagged inoculant
A seed-packet of rhizobia is agriculture, not a forest in a sachet.
Public-health desks
Garden soil can carry tetanus spores. Public vaccine advice belongs to clinicians, not this atlas.

Frequently asked questions
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.
Can I cite these scores externally?
Treat them as atlas orientation, not certificates or forecasts.
What should I check before acting?
Primary desks for Beneficial allies: public-health desks and lab teaching frames.
