The present study was supported by the project RESCLICONT (CGL2016-80981-R) funded by MCIN/AEI/10.13039/501100011033/ and FEDER A way to make Europe. A. Peñalver-Alcalá was hired by the project RESCLICONT. M.N. González-Alcaraz holds a Ramón y Cajal research contract from the Spanish Ministry of Science and Innovation (RYC2020-029322-I). We much appreciate the help of M. Carmen Tercero, Héctor M. Conesa and Irene Sánchez during field and laboratory work. Francisco J. Jiménez-Cárceles, from Biocyma environmental consulting, helped us in vegetation field work. We thank to the technicians of the SAIT-UPCT for their laboratory and analytical assessments.Realizado en/con

Resumen
This study aimed to evaluate whether the improvement in soil conditions induced by the vegetation spontaneously colonizing abandoned metal(loid) mine tailings from semiarid areas is consistent throughout seasons and to identify if the temporal variability of that conditions is of similar magnitude of that of the surrounding forests. Soil climatic (temperature and moisture), chemical (pH, electrical conductivity and water-soluble salts and metal(loid)s) and biological (water-soluble organic carbon and ammonium, microbial biomass carbon, dehydrogenase and β-glucosidase activity, organic matter decomposition and feeding activity of soil dwelling organisms) parameters were seasonally evaluated for one year in bare soils and different vegetated patches within metalliferous mine tailings and surrounding forests in southeast Spain. The results indicated that the improvement in soil conditions (as shown by softening of climatic conditions and lower scores for salinity and water-soluble metals ...
