Soil samples were collected at 0–1, 1–2, and 2–3 cm depths in triplicate just before the burn, immediately after the burn (T0), and 1 and 5 years later (T1 and T5). We analysed the contents of total soil organic C and N, soil respiration, microbial biomass C, and ß-D-glucosidase and acid phosphatase activities. Fire provoked an immediate high decrease in the contents of soil organic C (-40.2%) and N (-26.3%) in the first 3 cm, which were even lower at T5 (-50.3% and -46.5%, respectively). This can be explained as follows: (a) low incorporation of burned organic matter due to removal by wind and run-off; (b) changes in microclimate increasing soil temperature and enhancing mineralization; and (c) a stimulating effect on decomposition due to the release of nutrients. Soil biological activity was affected at T0 in the first 3 cm (-49.3% glucosidase, -48.2% phosphatase, and -54.5% respiration rate). Microbial biomass C content was also affected by fire at T0 (-32.3%) but was close to its initial value at T5. The results suggest that these soils are particularly sensitive to fire. Adjusting the frequency and intensity of the burns is necessary to minimize their impact on the soil and to ensure the suitability of this management practice 000078727 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/CGL2013-43440-R 000078727 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000078727 590__ $$a4.275$$b2018 000078727 591__ $$aENVIRONMENTAL SCIENCES$$b54 / 250 = 0.216$$c2018$$dQ1$$eT1 000078727 591__ $$aSOIL SCIENCE$$b5 / 35 = 0.143$$c2018$$dQ1$$eT1 000078727 592__ $$a1.437$$b2018 000078727 593__ $$aDevelopment$$c2018$$dQ1 000078727 593__ $$aSoil Science$$c2018$$dQ1 000078727 593__ $$aEnvironmental Science (miscellaneous)$$c2018$$dQ1 000078727 593__ $$aEnvironmental Chemistry$$c2018$$dQ1 000078727 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000078727 700__ $$0(orcid)0000-0003-0630-1181$$aMartí, Clara$$uUniversidad de Zaragoza 000078727 700__ $$0(orcid)0000-0002-1006-5030$$aBadía, David$$uUniversidad de Zaragoza 000078727 700__ $$0(orcid)0000-0003-3516-5756$$aOrtiz Perpiñá, Oriol$$uUniversidad de Zaragoza 000078727 700__ $$0(orcid)0000-0001-7003-8950$$aGirona García, Antonio$$uUniversidad de Zaragoza 000078727 700__ $$0(orcid)0000-0001-8146-0364$$aMora, Juan Luis$$uUniversidad de Zaragoza 000078727 7102_ $$15011$$2705$$aUniversidad de Zaragoza$$bDpto.
