    <dc:description>Open Access[SPA] El fitomanejo permite reducir el riesgo ambiental de balsas mineras abandonadas. El objetivo del trabajo fue evaluar la movilidad de metales en balsas mineras enmendadas con biochar y/o compost urbano y la efectividad de las enmiendas reduciendo la toxicidad de la soluci&#243;n ed&#225;fica para una planta pionera (Zygophyllum fabago). Se llev&#243; a cabo un experimento en mesocosmos (20 meses) con residuo minero con y sin enmienda. Los mesocosmos se mantuvieron a capacidad de campo con agua de la red y se drenaron en diferentes momentos. Se monitoriz&#243; la soluci&#243;n ed&#225;fica regularmente (pH, conductividad el&#233;ctrica, carbono org&#225;nico soluble &#8211;COS--, nitr&#243;geno total soluble &#8211;NTS- y metales -Mn, Zn-), al igual que el drenaje. Se realiz&#243; un bioensayo con semillas de Z. fabago con la soluci&#243;n ed&#225;fica de mitad del experimento (germinaci&#243;n de semillas, crecimiento de pl&#225;ntulas). Los tratamientos con compost urbano mostraron mayor concentraci&#243;n inicial de COS y metales en soluci&#243;n. Se observ&#243; un descenso temporal de la concentraci&#243;n de DOC y metales en la soluci&#243;n ed&#225;fica debido a su lixiviaci&#243;n en el drenaje. A pesar del mayor contenido de metales, el compost urbano favoreci&#243; la elongaci&#243;n de la ra&#237;z debido al mayor contenido de COS y NTS en soluci&#243;n. [ENG] Phytomanagement allows to reduce the environmental risks of abandoned mine tailings. The aim of this work was to assess metal mobility in mine tailings amended with biochar and/or urban compost and the effectiveness of these amendments for reducing the toxicity of soil solution to a pioneer plant species (Zygophyllum fabago). A mesocosm experiment was performed (20 months) with mine wastes with and without amendment. Mesocosms were maintained at field capacity with tap water and drained at different times. Soil solution was regularly monitored (pH, electrical conductivity, dissolved organic carbon &#8211;DOC-, dissolved total nitrogen &#8211;TDN- and metals -Mn, Zn-), as well as drainage. A bioassay with seeds of Z. fabago was performed with midterm soil solution (seed germination, seedling performance). Treatments containing urban compost showed higher initial DOC and metal concentrations in solution. A decrease of DOC and metal concentrations in soil solution with time occurred due to their lixiviation in the drainage water. In spite of the higher metal pool, urban compost favoured root length due to its greater content of DOC and TDN in soil solution. </dc:description>
