Dinámica estacional de la biomasa microbiana y actividades enzimáticas en suelos agrícolas mediterráneos: manejo convencional vs. ecológico

Abstract

Con el fin de reducir el impacto ambiental causado por los fertilizantes de origen mineral, el sector vitivinícola se dirige hacia un modelo sostenible. El uso de fertilizantes orgánicos es una práctica común en el avance hacia este modelo de gestión, aportando materia orgánica al suelo y repercutiendo en la mejora de las características físico-químicas y biológicas de éste. Además, también han de ser capaces de aportar el nitrógeno necesario para el correcto desarrollo del cultivo. Para comparar el efecto de un fertilizante mineral frente a un fertilizante orgánico en suelo, se realizó un seguimiento estacional de la cantidad de nitratos, y diferentes parámetros biológicos relacionados con el C y el N (carbono y nitrógeno de la biomasa microbiana, hidrólisis del diacetato de fluoresceína y las actividades β-glucosidasa y β-galactosidasa) en una parcela convencional y una ecológica en un viñedo comercial en Mallorca. Los resultados tras dos años de aplicación mostraron que el efecto de las aplicaciones (mineral y orgánica) provocaron tendencia a aumentar los valores de las variables biológicas gracias al aporte de nutrientes, siendo más notable el efecto del fertilizante mineral sobre su control.
