Abstract
Los suelos, esenciales para el bienestar humano y ecosistémico, enfrentan amenazas como la compactación y pérdida de diversidad. Las lombrices de tierra desempeñan un papel clave en el equilibrio del suelo, influyendo en la biodiversidad y procesos biogeoquímicos. Este estudio analiza cómo la presencia de lombrices y biocarbón afecta la actividad enzimática del suelo. Utilizando un mesocosmo con cuatro tratamientos (suelo control, suelo con biocarbón, suelo con lombrices, y suelo con lombrices y biocarbón), se evaluaron diez enzimas importantes para la calidad ambiental y agronómica. Los resultados indicaron que la combinación de biocarbón y lombrices aumentó significativamente la actividad de las enzimas proteasa y glucosidasa, mejorando la descomposición de la materia orgánica y la disponibilidad de nutrientes. Se destaca que el biocarbón con sus propiedades beneficiosas como alta recalcitrancia y pH alcalino, puede complementar los efectos positivos de las lombrices, aunque las interacciones biológicas aún son poco comprendidas. En conclusión, este estudio demuestra que el uso combinado de lombrices y biocarbón podría ser una estrategia efectiva para mejorar la calidad del suelo.
Soils, essential for human and ecosystem well-being, face threats such as compaction and loss of diversity. Earthworms play a key role in soil balance, influencing biodiversity and biogeochemical processes. This study analyzes how the presence of earthworms and biochar affects soil enzymatic activity. Using a mesocosm with four treatments (control soil, soil with biochar, soil with earthworms, and soil with both), ten enzymes important for environmental and agronomic quality were evaluated. The results indicated that the combination of biochar and earthworms significantly increased the activity of protease and glucosidase enzymes, enhancing organic matter decomposition and nutrient availability. The discussion highlights that biochar, with its beneficial properties such as high recalcitrance and alkaline pH, can complement the positive effects of earthworms, although the biological interactions are still poorly understood. This study shows that the combined use of earthworms and biochar could be an effective strategy to improve soil quality.
