Summary

This 2017 study investigated the chemical evolution of preindustrial charcoal particles over long timescales in temperate European soils, comparing weathering trajectories between forest and agricultural land uses. By analysing aged charcoal samples using geochemical methods, the authors characterised how soil environment influences charcoal reactivity and persistence—properties relevant to understanding soil carbon stability and the legacy of historical land management. The findings contribute to knowledge of how charcoal (biochar and natural pyrogenic carbon) behaves in contrasting soil systems.

UK applicability

Results are directly applicable to UK temperate soils, where similar preindustrial charcoal deposits exist and where biochar application is increasingly used in regenerative farming. Understanding charcoal persistence and chemical alteration informs predictions of carbon sequestration durability and long-term soil amendment efficacy in UK agricultural and forest contexts.

Key measures

Chemical properties of charcoal particles (composition, functional groups, oxidation state) in aged samples from forest and agricultural soil profiles

Outcomes reported

The study examined long-term chemical transformations of preindustrial charcoal particles as they aged in contrasting soil environments (forest versus agricultural temperate soils). Measurements tracked changes in charcoal chemical properties over time to understand persistence and reactivity.
