Can we cut N2O without cutting food?
Timing, form and wetlands matter. Agronomy, not a slogan.
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.
