Prescribed biomass burning effects on soil NO emissions in South Carolina.

ABSTRACT: Nitrogen oxides (NO_x = NO + NO₂) are key atmospheric trace gases that affect air quality, oxidation chemistry, and nitrogen deposition. Although anthropogenic NO_x emissions have declined due to regulations, natural sources like soil emissions are becoming relatively more important. Biomass burning can alter soil nitrogen cycling and potentially influence soil NO fluxes, yet few controlled studies exist. Here, we examined how prescribed burning affects soil NO emissions in a South Carolina forest using incubation experiments. The study site is a sandhill ecosystem dominated by upland oak and longleaf pine, with fire-adapted understory vegetation including wiregrass. Soil cores were collected before and after burns of varying intensities. Measured soil pH, ni
