Grassland ecosystems play a crucial role in carbon storage and greenhouse-gas management, but the effects of grassland management practices and environmental drivers remain unclear. Our study found that methane (CH₄) emissions are primarily controlled by soil moisture, whereas nitrous oxide (N₂O) emissions are more strongly affected by temperature. The grassland functioned as a small carbon sink during the observation period, highlighting the need for longer-term research to better understand how different management practices influence greenhouse gas emissions over time.
