Timing, form and wetlands matter. Agronomy, not a slogan.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Nitrogen cycle?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Nitrogen cycle?
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 Nitrogen cycle?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Nitrogen cycle 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.
Comammox and anammox keep rewriting textbooks. Field rates still disagree with models.
The frontier is less waste, not a more aggressive fixer recipe for a garage.
Open questions
Who are the complete oxidisers?
Comammox Nitrospira collapsed a two-step dogma in 2015 papers.
Can legumes replace more Haber-Bosch?
Partly, on some soils. Yield and land are the constraints.
How do we treat wastewater cheaper?
Anammox plants exist. Scale and climate decide the rest.
What is a safe nitrate limit?
Codes differ. Infants and wells need local public-health numbers, not a blog.
Keep the circle honest: feed people, leak less, leave the garage kits alone.
