Mejora en la retención y distribución de agua en muros verdes usando materiales alternativos como medio de crecimiento

Y. A. Rivas-Sanchez, M. F. Moreno-Pérez, José Roldán-Cañas

Resumen

Este trabajo muestra como la fibra de coco mezclada con cascarilla de arroz es útil como medio de cultivo en muros verdes, reduciendo el impacto ambiental de la explotación de musgo Sphagnum a largo plazo. Por esto, se diseñó un prototipo de muros verdes para analizar la diferencia entre ambos sustratos. La escorrentía y la retención hídrica de los sustratos se analizaron mediante sensores de flujo y humedad. El sustrato compuesto de cascarilla de arroz y fibra de coco mostró mayor homogeneidad en la distribución del agua de riego que el musgo Sphagnum. Los análisis de clorofila mostraron diferencias estadísticamente significativas entre el material vegetal plantado en el sustrato de fibra de coco y cascarilla de arroz y en el de Sphagnum, pero no se encontraron diferencias en biomasa y en el contenido hídrico.
