Tillage does not impact soil greenhouse gas emissions in a Central Texas rainfed maize–cotton system
Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Agricultural soils are a significant source of greenhouse gas (GHG) emissions, primarily as N2O. Monitoring how management practices impact soil gas fluxes (CO2, CH4, and N2O) is useful for making sure conservation practices (e.g., no‐till) are sustainable with regards to all potential environmental impacts.

Lost in translation: the quest for Nitrosomonas cluster 7‐specific amoA primers and TaqMan probes
Microbial Biotechnology, 2020 Summary The choice of primer and TaqMan probes to quantify ammonia‐oxidizing bacteria (AOB) in environmental samples is of crucial importance. The re‐evaluation of primer pairs based on current genomic sequences used for quantification of the amoA gene ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress
Ecological Research, Volume 41, Issue 5, September 2026.This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Three Decades of Soil N2O Research—Insights and Gaps
Global Change Biology, Volume 32, Issue 8, August 2026.Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Estimation of Numbers of Nitrosomonas in Soil and Culture
Nature, 1956 ATTEMPTS to estimate the numbers of nitrifying organisms in soil have usually been made by some form of dilution technique involving culture of the dilutions in liquid media in tubes (see ref. 1). The number of dilutions, and of replicate tubes at each dilution, that are necessary to give reliable estimates, makes this method extravagant of material ...

STUDIES ON THE OXIDATION OF AMMONIA BY NITROSOMONAS [PDF]
Biochemical Journal, 1965 1. Free-energy calculations for pH7 showed that the oxidation of ammonia to hydroxylamine is endergonic and that the oxidations of hydroxylamine to nitrite and hydrazine to nitrogen are exergonic. It is suggested that the oxidation of ammonia requires the expenditure of energy. 2.
