Efectos del fuego prescrito sobre matorral en las propiedades del suelo

Abstract

Se evaluaron las propiedades edáficas en un segmento de pendiente de 2,68 ha del «monte Tuña», municipio de Tineo, afectado por quema controlada a hecho descendente de Erica y Ulex con un rendimiento de 1,5 ha/ h. Las alteraciones en el suelo, inmediatamente después de la quema y a los 7, 30 y 90 días, se produjeron a 0-2, 2-5 y 5-10 cm de profundidad, demostrando la existencia de un incremento temporal de la fertilidad de los suelos quemados (aumento de C, N, K, Ca, Mg y sobre todo de P asimilable). Justo después del fuego hubo una disminución de la fracción arcilla y un aumento de la fracción arena y viceversa a los 7, 30 y 90 días de la quema. El aumento de fertilidad tras la quema podría ser aprovechado para el rápido establecimiento de una cubierta vegetal debido a la brotación de la vegetación quemada.
