Abstract

We know little about how shifts in tree species distribution and increases in forest fire intensity could affect the formation of pyrogenic organic matter (PyOM) or charcoal, one of the most important and persistent soil organic matter pools. This limitation arises partly because the role of the precursor wood in controlling PyOM formation is unclear. The current study shows how tree species and pyrolysis temperature (200, 300, 450 and 600 °C) interact to control the physicochemical structure of the PyOM experimentally derived from 13
