Summary
This meta-analysis synthesises evidence on integrative nitrogen management approaches that combine agronomic, biological, and management knowledge to enhance ecosystem-level nitrogen retention. The authors suggest that knowledge-based practices—potentially including split applications, precision timing, organic amendments, and microbial inoculants—can reduce nitrogen losses whilst maintaining or improving crop productivity. The work contributes to understanding how holistic nitrogen stewardship can support both environmental and productive outcomes in farming systems.
UK applicability
The findings are likely applicable to UK arable and mixed farming contexts, where nitrogen management is a key regulatory and sustainability concern under the Water Environment (Water Framework Directive) Regulations and the Environmental Land Management Scheme. Knowledge-based nitrogen practices identified may align with UK Best Available Techniques guidance and emerging sustainable intensification policy.
Key measures
Nitrogen retention efficiency, nitrogen losses (leaching, gaseous emissions), soil nitrogen pools, crop nitrogen uptake
Outcomes reported
The study examined how integrative, knowledge-based nitrogen management practices affect nitrogen retention within agricultural ecosystems. The research likely evaluated multiple nitrogen cycling pathways and losses (e.g. leaching, denitrification, ammonia volatilisation) under different management scenarios.
