Summary
This field study applied a novel triple 15N tracing methodology to elucidate discrete nitrogen transformation pathways in UK grassland soil. By simultaneously tracking multiple nitrogen cycling processes using stable isotope labelling, the work contributes mechanistic understanding of soil nitrogen dynamics in temperate pasture systems. The findings are relevant to understanding nutrient availability and potential losses in grassland-based farming systems, as suggested by the methodological approach and grassland focus.
UK applicability
The findings are directly applicable to UK grassland and pasture management, as the study was conducted in UK soil conditions. Results may inform nutrient management practices and nitrogen loss mitigation strategies in temperate UK farming systems.
