From burned slopes to streams: how wildfire affects nitrogen cycling and retention in forests and fire-prone watersheds

RN Gustine, EJ Hanan, PR Robichaud, WJ Elliot - Biogeochemistry, 2022 - Springer
Wildfire is a major driver of nitrogen (N) cycling and export from terrestrial to aquatic
systems. While fire is a natural process in many watersheds, it can still degrade water quality …
