Short summary
To evaluate different mechanisms underlying nitrogen (N) pulses that occur following fires in pyrogenic US savannas, we coupled field measures of soil N cycling with soil N isotopic signatures. We found that neither ash deposition nor changes to microbial activity could account for observed N pulse. We hypothesize that changes to plant uptake may contribute to the post-fire N pulses. We encourage future work to explore the role of plant activity on temporal nutrient availability dynamics.
