Numerous studies have examined effects of wildfires and prescribed burns on soils, yet knowledge of the soil temperatures and durations reached is limited. This can lead to erroneous assumptions regarding fire impacts, especially when laboratory heating results are extrapolated to field conditions. Aims and Methods We compiled new and published data on maximum temperatures and heating durations for mineral soils during wildfires and prescribed burns in forests, shrublands and grasslands around the globe, and compared these to data from laboratory heating experiments. Key results Most fires heated only the uppermost centimetres of the soil, rarely exceeding 300°C below 0.5 cm depth. Where 300°C was exceeded at the soil surface, heat pulses were shorter (<500 s) than those often applied in laboratory studies (30 min to 1 h). The highest near-surface temperatures occurred in shrubland wildfires (~964ºC), and longest heating durations in forests with deep duff layers (>3 h above 60°C). Conclusions and Implications Most fires, except in deep smouldering fuels, generate short and shallow soil heating. Laboratory studies with long heating durations rarely represent field conditions. When investigating fire effects on soil, inclusion of shallow near-surface layer samples is recommended. 000167879 536__ $$9info:eu-repo/grantAgreement/EC/H2020/101003890/EU/FIREURISK - DEVELOPING A HOLISTIC, RISK-WISE STRATEGY FOR EUROPEAN WILDFIRE MANAGEMENT/FirEUrisk$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101003890-FirEUrisk$$9info:eu-repo/grantAgreement/ES/MICINN/RYC2021-031262-I$$9info:eu-repo/grantAgreement/ES/MICINN/PID2023-146991NA-I00 000167879 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000167879 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000167879 700__ $$aGirona-García, Antonio 000167879 700__ $$aSanchez-Garcia, Carmen 000167879 700__ $$0(orcid)0000-0002-1006-5030$$aBadía-Villas, David$$uUniversidad de Zaragoza 000167879 700__ $$aBryant, Rob 000167879 700__ $$aDickinson, Matthew 000167879 700__ $$aHsieh, Rex 000167879 700__ $$aMataix-Solera, Jorge 000167879 700__ $$aMiesel, Jessica 000167879 700__ $$aRobichaud, Peter 000167879 700__ $$aStoof, Cathelijne 000167879 700__ $$aSantín, Cristina 000167879 7102_ $$15011$$2240$$aUniversidad de Zaragoza$$bDpto.
