Abstract
Esta investigación se enfoca en la evaluación de la rehabilitación de un material de cubierta sobre un relleno de cenizas derivado de la actividad termoeléctrica en la ciudad de Coronel, Chile. El objetivo del proyecto fue comparar la efectividad de recuperación de funciones edáficas de diferentes tratamientos de cobertura de suelos complementarias a las acciones la plantación de especies leñosas nativas. Lo anterior se realizó mediante el análisis de indicadores biológicos como la respiración del suelo, carbono (%) y presencia de lombrices. Los resultados revelan que la adición de coberturas y semillas de pastos permite una sucesión superior al proceso espontáneo en el ecosistema, acelerando la recuperación de la funcionalidad edáfica y la calidad del suelo. Se identificaron diversos procesos asociados al suelo que generan beneficios tanto para el ecosistema como para la comunidad humana. En conclusión, este estudio demuestra que la combinación del sellado, relleno, plantación de especies leñosas nativas y tratamientos de cobertura de suelo es una estrategia efectiva para la rehabilitación de suelos degradados por la actividad termoeléctrica. Estos hallazgos proporcionan una base sólida para futuros esfuerzos de procesos de investigación y actividades de restauración ecológica en áreas similares, promoviendo la recuperación de los ecosistemas boscosos y el bienestar de la comunidad que los rodea.
This research focuses on the evaluation of the rehabilitation of a cover material on an ash fill derived from thermoelectric activity in the city of Coronel, Chile. The objective of the project was to compare the effectiveness of recovery of edaphic functions of different soil cover treatments complementary to the actions of planting native woody species. This was done by analyzing biological indicators such as soil respiration, carbon (%) and earthworm presence. The results reveal that the addition of grass cover and seeds allows a succession superior to the spontaneous process in the ecosystem, accelerating the recovery of edaphic functionality and soil quality. Several soil-associated processes were identified that generate benefits for both the ecosystem and the human community. In conclusion, this study demonstrates that the combination of sealing, backfilling, planting of native woody species and ground cover treatments is an effective strategy for the rehabilitation of soils degraded by thermoelectric activity. These findings provide a solid basis for future research process efforts and ecological restoration activities in similar areas, promoting the recovery of forest ecosystems and the surrounding community's well-being.
