What is a potential disadvantage of agroforestry systems?
EXPLANATION
Agronomy, Tillage & Field Crop Production
- Enhanced susceptibility to pests: In some agroforestry combinations, woody perennials can act as alternative, collateral, or over-wintering host plants for insect pests and fungal pathogens, potentially increasing pest pressure on adjacent companion crops. (Correct answer)
- Soil erosion: Agroforestry systems significantly reduce water and wind erosion through protective tree canopy cover and root anchoring.
- Carbon sequestration: Integrating woody trees with crops markedly enhances both aboveground biomass and soil organic carbon sequestration.
- Biodiversity: Multi-strata agroforestry increases floral and faunal biodiversity by creating diverse micro-habitats.
