Description

  • This article discusses how to manage an agroforestry coffee system to maintain crop productivity while also promoting biodiversity in Costa Rica.
  • Coffee (Coffea arabica var caturra) was planted underneath three native shade species (Terminalia amazonia, Erythrina poeppigiana, and Chloroleucon eurycyclum), both separately and in combination, and also as a non-shaded coffee monoculture.
  • Furthermore, the various plots were treated with either organic or chemical inputs at two intensity levels. 
  • Both vegetative and crop productivity were measured across all combinations of shade species and management practices.
  • High-intensity inputs, both organic and chemical, caused a sharp decrease in herbaceous species richness compared to medium-intensity inputs suggesting that the latter may be optimal for balancing optimal coffee yields with biodiversity conservation.
  • Undesirable grass species were less common in the shaded plots compared to the full sun monoculture.
  • The authors suggest that the shaded coffee grown in the plot including all three native shade species would probably provide the most benefits to farmers, including shade, mulch, and timber.
