DOI: 10.1002/jeq2.20495
Abstract: Denitrification, the anaerobic microbial conversion of nitrate (NO3 - ), a common water pollutant, to nitrogen (N) gases, is often high in the soil of natural wetlands. In areas where natural wetlands have been degraded… read more here.

Regulation of denitrification/ammonia volatilization by periphyton in paddy fields and its promise in rice yield promotion.
Sign Up to like & getrecommendations! Published in 2022 at "Journal of the science of food and agriculture"
DOI: 10.1002/jsfa.12403
Abstract: BACKGROUND Nitrogen (N) is the most limiting nutrient in rice production. N loss via denitrification and ammonia (NH3 ) volatilization decreases N utilization efficiency. The effect of periphyton, which are widespread soil surface microbial aggregates… read more here.

DOI: 10.1002/lno.12627
Abstract: Past changes in the input/output, and internal cycling, of bioavailable nitrogen (N) in marine and lacustrine environments can be reconstructed by analyzing the N isotopic composition (δ15N) of organic matter in the sedimentary record. To… read more here.

DOI: 10.1007/s00248-017-0991-1
Abstract: More than 50% of all anthropogenic N2O emissions come from the soil. Drained Histosols that are used for agricultural purposes are particularly potent sources of denitrification due to higher stocks of organic matter and fertiliser… read more here.

DOI: 10.1007/s00374-023-01783-9
Abstract: Acid-sulphate sugarcane soils in the subtropics are known hot-spots for nitrous oxide (N_2O) emissions, yet the reduction of reactive N_2O to non-reactive dinitrogen (N_2) via specific pathways remains a major uncertainty for nitrogen (N) cycling… read more here.
