Other claims from this paper (12)
- Observation Measured cocoa agroforestry variables in savannah and forest systems tended toward comparable levels after several decades.
- Observation Savannah cocoa agroforestry increased most ecosystem services, including soil fertility and plant diversity.
- Observation Cocoa yield did not vary between monoculture and agroforestry systems.
- Observation Soil phosphorus availability improved in cocoa agroforestry relative to monoculture.
- Observation Unshaded cocoa had the lowest soil functions within agroforestry systems.
- Intervention effect Canarium schweinfurthii association did not improve cocoa soil fertility compared with unshaded cocoa.
- Intervention effect Dacryodes edulis association did not improve cocoa soil fertility compared with unshaded cocoa.
- Intervention effect Albizia adianthifolia association significantly improved soil nitrogen and phosphorus availability.
- Intervention effect Milicia excelsa association significantly improved soil nitrogen and phosphorus availability.
- Intervention effect Ceiba pentandra association significantly improved soil nitrogen and phosphorus availability.
- Association Soil pH and carbon content increased with litter calcium restitution from C. pentandra.
- Recommendation The authors conclude that specific trees selected for soil quality and goods can support cocoa agroforestry multifunctionality and sustainability.
