Aerobic nitrification is a key process in the global nitrogen cycle mediated by microorganisms. While has primarily been studied near-neutral environments, this occurs at wide range of pH values, spanning ecosystems from acidic soils to soda lakes. through activities ammonia-oxidising bacteria and archaea, nitrite-oxidising bacteria, complete (comammox) adapted these environments. Here, we review literature identify knowledge gaps on metabolic diversity, ecological distribution, physiological adaptations nitrifying microorganisms alkaline We emphasise that depend suite maintain homeostasis, acquire energy carbon sources, detoxify reactive species, generate membrane potential extremes. also recognize broader implications their with focus agricultural productivity nitrous oxide emissions, as well promising applications treating municipal wastewater.

Large-scale information regarding nitrous oxide (N2O) emissions is needed as an evidence base to underpin land use policy and mitigation approaches. However, the highly variable rates of denitrification make prediction N2O emission demanding. Here, we evaluated role abiotic biotic factors on potential Irish soils, in order identify key regulating at a large scale. To do so, collected 136 soil samples from 32 sites across Ireland, characterised physico-chemical properties, prokaryotic fungal community composition, abundance N-cycling genes nitrification, end product N2O/(N2O + N2). We found differences between (up 41.5 mg N2O–N kg−1 day−1) with most released form rather than N2. Soils highest nitrification also exhibited rates, similar parameters were linked both processes.

Soil phosphorus content was important for predicting pH total nitrogen. microbial structure, denitrifier abundance, predictor end-product composition more strongly associated resulting end-products communities.

Altogether, these results lay foundation better understanding soils that enhance larger scales.

Knowledge about global patterns of the decomposition kinetics distinct soil organic matter (SOM) pools is crucial to robust estimates land-atmosphere carbon fluxes under climate change. However, current Earth system models often adopt globally-consistent reference SOM rates (kref), ignoring effects from edaphic-climate heterogeneity. Here, we compile a comprehensive set edaphic-climatic and data published incubation experiments employ machine-learning techniques develop capable predicting expected sizes kref multiple (fast, slow, passive). We show that texture dominates turnover fast pools, whereas pH predominantly regulates passive decomposition. This suggests pH-sensitive bacterial decomposers might have larger on stable than previously believed. Using these predictive models, provide 1-km resolution global-scale dataset which may improve biogeochemical model parameterization predictions.

Abstract Grazing exclusion alters grassland soil aggregation, microbiome composition, and biogeochemical processes. However, the long‐term effects of grazing on microbial communities nutrient dynamics within aggregates remain unclear. We conducted a 36‐year experiment to investigate how affects community associated functions in semiarid grassland. Long‐term (36 years) induced shift communities, especially <2 mm aggregates, from high low diversity compared control. The reduced was accompanied by instability fungal extended distribution pathogens >2 carbon (C) sequestration potential thus revealing negative impact GE. In contrast, 11–26 years greatly increased C promoted cycling functional genes. Moreover, environmental characteristics microhabitats (e.g., pH) altered strongly contributed sequestration. Our findings reveal new evidence microbiology for optimizing duration maintain multiple belowground ecosystem functions, providing promising suggestions climate‐smart resource‐efficient grasslands.

Denitrification – a key process in the global nitrogen cycle and main source of greenhouse gas N2O is intricately controlled by O2.

Here, agricultural soil exposed repeated cycles long or short anoxic spells (LA; SA) constant oxic conditions (Ox). Surprisingly, reduction rates are three times greater Ox than LA SA during final incubation, despite comparable bacterial biomass gene abundances.
