Ciclos biogeoquímicos en un ecosistema forestal de los Andes Occidentales de Venezuela, 4: Modelos y conclusiones [suelos].

Following a basic model for biogeochemical cycling, the stores and transfers of N, P, K, Na, Ca, Mg, Mn, Fe and Al in the montane forest ecosystem of San Eusebio, Merida, Venezuela, are presented. The input layer of the ecosystem is the forest canopy; the output layer was placed at 120 cm below soil...
