Denitrification as a source of nitric oxide emissions from incubated soil cores from a UK grassland soil

Summary

This laboratory study examined denitrification as a source of nitric oxide emissions using soil cores from a UK grassland, employing controlled incubation methods to isolate and quantify NO production. The research contributes to understanding of greenhouse gas and reactive nitrogen losses from pastoral soils, which is relevant to quantifying the full radiative and eutrophication impact of grassland farming systems. The findings are as suggested by the experimental design intended to partition NO emissions from other nitrogen oxide pathways.

UK applicability

Direct applicability to UK grassland management: the soil cores were sourced from a UK site, making the findings directly relevant to understanding nitrogen oxide losses from British pastoral systems. Results may inform UK agricultural emissions inventories and mitigation strategies for reducing reactive nitrogen pollution from grasslands.

Key measures

Nitric oxide (NO) gas emissions; denitrification rates; soil core incubation conditions

Outcomes reported

The study quantified nitric oxide (NO) emissions from denitrification processes in incubated soil cores collected from a UK grassland. As suggested by the title, the research measured NO as a direct product of soil denitrification under controlled laboratory conditions.
