Summary
This 2016 laboratory study used soil core incubations to investigate nitric oxide emissions from denitrification in grassland soils sampled from the United Kingdom. The work quantified the contribution of the denitrification pathway to NO losses—a greenhouse gas and air pollutant precursor—under controlled conditions. The findings contribute to understanding soil-derived nitrogen oxide dynamics relevant to grassland management and atmospheric chemistry.
UK applicability
The study directly characterises NO emissions from UK grassland soils, providing empirical data on denitrification-derived losses under British soil and climatic conditions. These data are directly applicable to UK grassland management, nitrogen fertiliser guidance, and air quality inventories.
Key measures
Nitric oxide (NO) gas emissions; denitrification rates; soil nitrogen pools; incubation conditions (moisture, temperature)
Outcomes reported
The study quantified nitric oxide gas losses arising from denitrification in UK grassland soil cores under controlled laboratory conditions. The research characterised the magnitude and pathways of NO emissions as a function of soil moisture, temperature, and nitrogen availability.
