Description

  • The goal of this study was to analyze the effect that different agroforestry systems have on the recolonization of macrofauna in the soil of former pasture lands.
  • This study takes place at an experimental resarech station on abandonded pastureland. Four treatments were tested:  1. a high-input silvopastoral system (ASPh), 2. a low-input silvopastoral system (ASPl), 3. a palm based system with four tree crop species (AS1) and 4. a high-diversity tree crop system with ten tree crop species (AS2). The control was a spontaneous fallow.
  • While the density of microfauna was comparable across systems, the species richness was significantly higher in ASPh and ASPI systems suggesting that cover crop plays an important role in creating a favorable environment for soil fauna. There were also differences in faunal density between speices with faster growing species having significantly more soil fauna than slower growing species.
