Resumen
Descripción
The analyze of the effect of different agroforestry systems wich were planted on degraded pasture land on the recolonization of the soil by the macrofauna. There was also try to identify indicator organisms for the regeneration state of the soil. Conclusions: the investigation of the soil fauna communities of four agroforestry systems in central Amazonia allowed to identify some factors wich may contribute to a rapid establishment of the fauna after land clearing for agricultural use; of particular importance seem to be a permanent soil cover, e.g., ground cover of fodder crops, and the development of a litter layer. Their presence resulted in a higher diversity of the soil fauna in the silvopastoral than in the agrosilvopastoral systems.
