We are investigating the biotic and abiotic controls of volatile organic compound (VOC) and reactive N emissions from forest soils. VOCs and reactive N (e.g., HONO, NO) emitted from forests contribute significantly to the production of ozone in urban and regional environments, and represent a major source of reactive at the global scale. Aboveground plant tissues have long been considered the primary emitters of reactive gasses within forests but recent studies suggest that roots and soil microbes emit reactive compounds through their metabolic activities.
