Abstract
Cytisus scoparius es una planta arbustiva ampliamente distribuida por todo el mundo y considerada como una amenaza para otras especies en algunos países. Las plantas del género Cytisus crecen sobre todo en áreas perturbadas y su presencia favorece, a menudo, la propagación rápida del fuego. El objetivo de este estudio fue evaluar el proceso de vermicompostaje de estos arbustos para producir un fertilizante orgánico de alta calidad y libre de polifenoles. El vermicompostaje redujo sustancialmente la biomasa de C. scoparius (en un 84%), fundamentalmente como resultado de la pérdida de sólidos volátiles, en tan sólo 6 semanas. Se obtuvo un vermicompost de calidad, que es un material similar a la turba, rico en nutrientes y microbiológicamente activo y estable, y sin la fitotoxicidad asociada a los polifenoles. Simultáneamente, la población inicial de lombrices se incrementó muy considerablemente, en un 350%. El procedimiento descrito es eficaz, simple y económico, y puede escalarse fácilmente para su aplicación industrial
Wild shrubs belonging to Cytisus scoparius are widely distributed throughout the world, and they are considered a threat to other species in some countries. Cytisus spp. mainly grow in disturbed areas and their presence often favours the rapid spread of fire. Theaim of this study was to evaluate whether such shrubs could be processed by vermicomposting on an industrial scale to yield high-quality organic and polyphenol-free fertiliser. Vermicomposting reduced thebiomass of C. scoparius substantially (by 84%), mainly as a result of the loss of volatile solids. After 6 weeks, the process yielded anutrientrich, microbiologically active and stabilised peat-like material without the polyphenol-associated phytotoxicity. Simultaneously, the initial population of earthworms increases remarkably, up to 350%. The procedure described is effective, simple and economical, and could easily be scaled up for industrial application
