Key Points

This research investigates how wildfire severity affects dissolved organic matter (DOM) in eucalypt forest soils.
Characterization of DOM using H NMR signals
Comparison of samples from two eucalypt forests
Analysis of soil properties related to wildfire effects.
Wildfire significantly alters the composition of DOM, particularly in loamy soils
Long-term changes in DOM impact carbon cycling
Ecosystem recovery is influenced by these alterations in DOM.

Implication

Examines wildfire effects on dissolved organic matter dynamics in eucalypt forests, indicating significant ecosystem impacts.

Abstract

H NMR signals. Our findings highlight that wildfire can impart long-term changes to DOM, particularly in loamy soils, with implications for carbon cycling and ecosystem recovery.
