Job Overview


Find Solutions to Agricultural Problems that Affect Americans Every Day, From Field to Table

The Agricultural Research Service (ARS) is the United States Department of Agriculture's chief scientific research agency and one of the world's premiere scientific organizations.  ARS Postdoctoral Research Associates are hired to supplement a lead scientist's research on agricultural problems of high national priority affecting American agriculture.

The incumbent will be assigned to the Soil Biogeochemistry Program, which conducts research of regional, national, and international interest, located within the USDA-ARS Columbia Plateau Conservation Research Center (CPCRC), Pendleton, OR. The research is part of the GRACEnet  (Greenhouse Gas Reduction through Agricultural Carbon Enhancement network) and REAP (Renewable Energy Assessment Project) projects under National Program (NP) 212, Climate Change, Soils and Emissions Research. The incumbent will work collaboratively with other federal and international agencies, universities, and private companies.



You will (1) use existing database and soil C data collected at GRACEnet (Greenhouse Gas Reduction through Agricultural Carbon Enhancement network), REAP (Renewable Energy Assessment Project) and selected GRA (Global Research Alliance) sites to develop soil C database; (2) setup required climate, cropping system, management, and soil files for diverse soils and climates to predict impact of various agricultural management practices on soil C changes; (3) provide predictive runs for soil organic C changes and CO2 emissions under potential climate change scenarios using the CQESTR model; (4) quantify effects of crop rotation, tillage intensity, fertilization, and potential temperature and precipitation changes due to climate change for each site and compare results with other process-based  models and IPCC estimates; and (5) identify best management practices that maximize C sequestration and greenhouse gas mitigation; and (6) summarize results in reports and publish simulation results.  You will access off-site experiments and will be required to possess a valid state-issued driver's license.
