Summary
This 10-year field experiment in temperate grassland quantified the integrated greenhouse gas budget of two contrasting management systems through continuous and periodic flux measurements. The study documents how management decisions and inter-annual climate variation jointly shape the net climate impact of grassland agriculture, providing empirical evidence for carbon accounting in European pastoral systems. As suggested by the experimental design, the findings contribute to understanding trade-offs between productivity and climate mitigation in managed grasslands.
UK applicability
The study's temperate grassland conditions and European management contexts are broadly applicable to UK pastoral systems. Findings on how management intensity and weather affect net greenhouse gas balance are directly relevant to UK climate reporting and farm-level carbon footprinting, though UK-specific validation studies would strengthen applicability to variable British rainfall and soil conditions.
Key measures
Greenhouse gas flux measurements (carbon dioxide, methane, nitrous oxide); net ecosystem carbon balance; soil carbon stock changes; management variables (fertilisation, cutting, grazing); weather and climatic variables
Outcomes reported
The study quantified net greenhouse gas budgets (CO₂, CH₄, N₂O) for two grassland management systems over 10 years, accounting for both soil and atmospheric flux measurements. It examined how management practices and inter-annual weather variation influence the overall climate footprint of temperate European grassland agriculture.
