Agricultural Research Service (ARS)
Grazinglands Research Laboratory
U.S. Department of Agriculture
El Reno, OK


Project Description:

A postdoctoral research opportunity is available with the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) Grazinglands Research Laboratory in El Reno, OK.   The selected applicant will quantify metabolic, enteric and methane emissions from beef cattle grazing extensive systems composed of native prairie, improved grasslands, or winter wheat.  Technologies must be developed or adapted and corroborated to scale from point to field scales.  Collaborative research on forage and animal efficiency, monitor C, N, and water cycling, utilization, and balance using eddy correlation towers and other technologies will be included as part of this appointment.


To be eligible, applicants must have received a doctorate degree with an interdisciplinary emphasis in micrometeorology, grazing ecology, and nutrient cycling within five years of the desired starting date.  Knowledge or experience in greenhouse gas emissions and nutrient cycling is desirable.   

The ideal candidate will have:

  • Skills in the use of eddy correlation methodology
  • Ability to apply GPS/GIS technologies to analyze grazing patterns
  • Knowledge of micrometeorology, cattle grazing behavior, and forage diets
  • Knowledge of GraceNet or similar agroecological protocols
  • Demonstrated ability to publish in peer-reviewed journals

Additional desired skills and knowledge include laboratory analytical skills, including NIRS and gas chromatography and knowledge of agroecological and greenhouse gas models.

Participation in Grazing CAP team planning activities is essential and will offer opportunities to network and collaborate with an outstanding group of researchers, students, and Extension specialists.  The Grazinglands Research Laboratory is also the host to the Southern Plains Long Term Agro-ecosystem Research (LTAR) and the Southern Plains Regional Climate Hub.

While participants will not enter into an employment relationship with ARS, this position requires a pre-employment check and a full background investigation.

This opportunity is available to U.S. citizens, Lawful Permanent Residents (LPR) and foreign nationals.

This is an equal opportunity program open to all qualified individuals without regard to race, color, age, sex, religion, national origin, mental or physical disability, genetic information, sexual orientation, or covered veteran’s status.
