Leaf decomposition and nutrient release in montane forests of northwestern Argentina

Acenolaza Pablo G., . and Lancho Juan F. Gallardo, . Leaf decomposition and nutrient release in montane forests of northwestern Argentina. pp. 619-630. ISSN 0128-1283

This study aimed to gain further insight into the leaf decomposition dynamics in Alnus acuminata forests through their nutrient release patterns. Three forests of different ages in San Javier mountains (Tucuman NW Argentine) were selected in order to know the evolution of the nutrient release process using the litterbag method in a forest chronosequence. Decomposing leaf P and K contents decreased rapidly whereas Cu Fe and Zn tended to increase over time. The sequence of element loss during decomposition was in the following order: K P Na N Ca Mg. Only Ca Cu Fe and Mn showed statistical differences according to stand ages.

Abstract

This study aimed to gain further insight into the leaf decomposition dynamics in Alnus acuminata forests through their nutrient release patterns. Three forests of different ages in San Javier mountains (Tucuman NW Argentine) were selected in order to know the evolution of the nutrient release process using the litterbag method in a forest chronosequence. Decomposing leaf P and K contents decreased rapidly whereas Cu Fe and Zn tended to increase over time. The sequence of element loss during decomposition was in the following order: K P Na N Ca Mg. Only Ca Cu Fe and Mn showed statistical differences according to stand ages.
