Natural #soils are a major source of #N2O—a potent #greenhousegas and #ozone-depleting gas. Modeling shows global natural-soil #N2O #emissions rose from 1990–2023, with the #tropics dominating and #landcover strongly affecting estimates.
Treating #manure with a #nitrification inhibitor reduced #soil #N2O and #NO #emissions, while #manure #acidification improved short-term ammonium retention but increased N2O emissions in sandy soil—showing soil type matters for #nitrogen management.
A new sorbent-based method for measuring #soil #NitrousOxide (#N2O) #emissions produced results similar to standard methods with fewer samples. Longer sample stability could enable remote lab analysis and expand #SoilScience monitoring.
