Summary
This 2023 synthesis examines the relationship between soil organic nitrogen priming effects and nitrous oxide production, integrating multi-study evidence to clarify mechanistic pathways. The authors appear to identify how organic nitrogen mineralisation processes stimulate N₂O-producing microbial activity under field and laboratory conditions. The work likely informs soil management strategies to mitigate greenhouse gas emissions whilst maintaining nitrogen availability for crop production.
UK applicability
Findings are applicable to UK temperate arable and grassland soils where organic amendments and manure management are common. The synthesis may inform UK agricultural guidance on fertiliser and amendment timing to reduce N₂O losses whilst supporting soil fertility.
Key measures
Nitrous oxide (N₂O) emission rates; soil organic nitrogen mineralisation; microbial community response; priming intensity under different soil and management conditions
Outcomes reported
This synthesis integrates evidence on how organic nitrogen mineralisation primes soil microbial processes that produce nitrous oxide (N₂O), a potent greenhouse gas. The review synthesises findings across varied soil types and environmental conditions to identify key mechanistic and management controls.
