Manejo del suelo, Servicios ambientales, Agricultura alternativaResumen
En la Amazonía, el sistema de cultivo convencional de palma aceitera (Elaeis guineensis) está cambiando el paisaje a través del aumento de la deforestación, la pérdida de biodiversidad y el aumento del desgaste del suelo. En el municipio de Tomé-Açu (estado de Pará, Brasil) se propuso un sistema de cultivo alternativo basado en la inserción de la palma aceitera en Sistemas Agroforestales (SAF) con el fin de evaluar el impacto de este sistema en la calidad del suelo en comparación con el cultivo convencional. monocultivo). El objetivo de este estudio fue evaluar los impactos de dos tipos diferentes de SAF (con alta y baja diversidad de especies de plantas) sobre el porcentaje de colonización micorrícica (PCM) en palma de aceite y la densidad de esporas en el suelo en relación con convencionales. cultivo. Se evaluó PCM en raíces finas (diámetro ≤ 2 mm) y se recolectaron muestras de suelo (0-10 cm). La colonización de micorrizas en el cultivo de palma aceitera insertada en SAFs fue mayor en comparación con el monocultivo, por otro lado, la densidad de esporas fue mayor en el sistema convencional. El manejo de suelos basado en Sistemas Agroforestales con alta o baja diversidad de especies de plantas puede contribuir a la colonización de micorrizas en palma aceitera en la Amazonía.
