Plants can emit nitrous oxide (N2O), a major greenhouse gas, directly from foliage. This study provides evidence that plants, not just soil microbes, are significant sources of atmospheric N2O in forest ecosystems.

Area of Science:

  • Atmospheric Chemistry
  • Ecology
  • Plant Physiology

Context:

  • Nitrous oxide (N2O) is a potent greenhouse gas with uncertain emission sources.
  • Previous research attributed N2O production primarily to soil microbial processes.
  • Understanding all N2O sources is crucial for climate change mitigation.

Purpose:

  • To investigate and provide evidence for plant-mediated N2O emissions under natural conditions.
  • To measure N2O concentrations in forest canopies and compare them to background levels.
  • To determine if plants contribute to atmospheric N2O beyond soil emissions.

Summary:

  • Vertical profiles of N2O concentrations were measured in a mixed forest in China.
  • Significantly elevated N2O levels were detected at canopy height, exceeding background concentrations by up to 64.9%.

  • These findings indicate N2O efflux from foliage, suggesting plants are a direct source.

    • Impact:

    • This research identifies plants as a previously underestimated source of atmospheric N2O.
    • It highlights the importance of considering plant emissions in forest N2O budgets.
    • The findings contribute to a more comprehensive understanding of greenhouse gas cycling in ecosystems.
