USDA-ARS seeks a postdoctoral researcher to investigate soil nitrogen (N) dynamics of northeastern United States peatlands under different management regimes.  The postdoc will conduct research on nitrification and mineralization rates of peatlands in four management categories: (1) actively cultivated for cranberry, (2) previously cultivated for cranberry and fallow, (3) previously cultivated for cranberry and ecologically restored, and (4) natural peatlands without a history of cultivation. The postdoc will be expected to: develop manuscript on N transformation rates in active cranberry bogs, measure N transformation rates in cranberry bogs across management regime, and contribute to research on N budgets of peatlands. Ph.D. required. Knowledge of soil biogeochemistry and nitrogen cycling in peatlands desirable. To apply, send cover letter, CV, and references to Dr. Casey Kennedy, casey.kennedy@usda.gov.
