Summary
This field study examined the effectiveness of nitrification inhibitors in reducing nitrogen oxide emissions from permanent grassland soil across a range of soil moisture regimes. As suggested by the title and journal focus, the research addresses the trade-off between mitigating climate-forcing N2O emissions and managing reactive nitrogen losses, which is relevant to grassland management and fertiliser use efficiency in temperate systems. The findings may inform best-practice guidance on fertiliser additives in grazing systems, particularly regarding soil moisture-dependent performance.
UK applicability
The study's focus on permanent grassland soil under variable moisture conditions is directly applicable to UK grassland management, where soil moisture fluctuations are common. Findings may support the development of evidence-based recommendations for nitrification inhibitor use in UK temperate grazing systems.
Key measures
N2O, NO and N2 gas emissions; soil moisture levels; nitrification inhibitor treatment response
Outcomes reported
The study measured emissions of N2O, NO and N2 from permanent grassland soil treated with a nitrification inhibitor across varying soil moisture conditions. The research quantified how soil moisture regimes influence the efficacy of nitrification inhibitors in modulating gaseous nitrogen losses.
