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

Summary

This laboratory-based study examined denitrification as a source of nitric oxide emissions from grassland soil samples collected in the United Kingdom. Using incubated soil cores, the authors quantified NO production rates and the relative contribution of denitrification to total gaseous nitrogen losses. The work contributes to understanding soil nitrogen transformations and associated atmospheric emissions from pastoral systems.

UK applicability

Findings are directly applicable to UK grassland and pasture management, where reducing nitrous oxide and nitrogen oxide emissions remains a priority for both climate and air quality policy. Results may inform mitigation strategies for grassland intensification and fertiliser application practices.

Key measures

Nitric oxide (NO) flux rates; denitrification rates; soil nitrogen cycling processes

Outcomes reported

The study quantified nitric oxide (NO) emissions from denitrification processes in grassland soil cores under controlled laboratory conditions. It investigated the contribution of denitrification to total NO emissions from UK grassland soils.
