Abstract

Disturbance of terrestrial ecosystems may drive soil changes that extend far deeper into regolith and persist far longer than is currently appreciated. Typically, the influences of disturbances are studied aboveground and in surface soils, but many of the likely-affected processes govern regolith production deep in soil profiles.
If so, large-scale disturbances may serve an unappreciated role as drivers of change in the type and rate of processes responsible for generating soil, the very material upon which terrestrial ecosystems grow. However, few investigators have integrated the probable responses of deep-soil biogeochemistry to aboveground disturbances into a testable hypothesis.
