RETORNO POTENCIAL DE NUTRIMENTOS POR COMPONENTES SECUNDARIOS DE LA HOJARASCA EN COMUNIDADES VEGETALES DE NUEVO LEÓN

Abstract

La caída de hojarasca es un mecanismo muy importante en el ciclo de nutrientes de un ecosistema, por lo cual el objetivo del presente estudio fue determinar el retorno potencial de Ca, K, Mg y P y de micronutrimentos (Cu, Fe, Mn y Zn) a través de las estructuras reproductivas, ramas, corteza e insectos en cuatro comunidades vegetales del noreste de México. La hojarasca se recolectó en tres sitios del Matorral Espinoso Tamaulipeco (Crucitas, Campus y Cascajoso), y uno de bosque de pino-encino (Bosque Escuela), con intervalos de 15 días entre 2006 y 2007. En cada lugar se estableció una parcela (50 m x 50 m) con 10 trampas (1 m2). El calcio (138 kg ha-1 año-1) y fierro (372 g ha-1 año-1) son los elementos que más reciclan los componentes secundarios. El orden en la deposición de macronutrimentos se presentó de la siguiente manera Ca > Mg > K > P, mientras que para micronutrientes fue Fe > Mn > Zn > Cu. El aporte total de estos últimos a los componentes secundarios (Cu+Fe+Mn+Zn) para el Bosque Escuela, Crucitas, Campus y Cascajoso fue de 362.9, 588.5, 234.9 y 218.3 g ha-1 año-1, respectivamente. El correspondiente a micronutrimentos para todos los componentes secundarios representó de 93 a 99% del total de la deposición anual, en los que estos fueron la fuente principal de retorno potencial en los cuatro sitios investigados, mientras que las hojas no constituyen un elemento de aporte importante en el retorno de Cu, Fe, Mn y Zn.
