Non CO2 Gases

Working Group


To support common observations of soil N2O emissions from Common Experiment treatments at all LTAR sites.


  • To define a standardized minimum sampling design to address greenhouse gas questions across the LTAR network.
  • To identify LTAR sites that are able to analyze gas samples for other sites.
  • To coordinate use of LTAR Non-CO2 gas data to address network-wide questions.


List activities that are currently happening or that are planned for this working group.

Next steps (from Archbold meeting):

  • Work closely with Soil WG to coordinate ancillary soils data needs (e.g. soil moisture, temperature, mineral N etc.)
  • Send out survey to assess:
    • Current N2O measurement activities including
      • Treatments sampled
      • Frequency of measurement
      • Years of existing data
      • List of publications
      • Future plans
      • Existing equipment and labor commitment
      • Able to serve as consultant to other sites?
      • Share photos
    • Assess interest in contributing data for a paper on testing N2O models

The USDA Agricultural Research Service (ARS) Long-Term Agroecosystem Research network consists of 18 Federal and university agricultural research sites with an average of over 50 years of history. The goal of this research network is to ensure sustained crop and livestock production and ecosystem services from agroecosystems, and to forecast and verify the effects of environmental trends, public policies, and emerging technologies.
