Effects of Inga densiflora on the microclimate of coffee (Coffea arabica L.) and overall biomass under optimal growing conditions in Costa Rica
TL;DR: Investigating the impact of Inga densiflora, a very common shade tree in Central America, on the microclimate, yield and vegetative development of shaded coffee in comparison to coffee monoculture found Inga-shaded plantations appeared more advantageous than MC in optimal conditions.
Journal ArticleDOI
Changes in carbon stock and greenhouse gas balance in a coffee (Coffea arabica) monoculture versus an agroforestry system with Inga densiflora, in Costa Rica
Kristell Hergoualc'h,Kristell Hergoualc'h,Eric Blanchart,Ute Skiba,Catherine Hénault,Jean-Michel Harmand +5 more
TL;DR: In this article, the authors evaluated the net GHG balance in two adjacent coffee plantations, both highly fertilized (250 kg N ha-1 year-1): a monoculture (CM) and a culture shaded by the N2-fixing legume tree species Inga densiflora (CIn).
Journal ArticleDOI
Agroforestry associating coffee and Inga densiflora results in complementarity for water uptake and decreases deep drainage in Costa Rica
Patrice Cannavo,Julie Sansoulet,Jean-Michel Harmand,Pablo Siles,Erwin Dreyer,Erwin Dreyer,Philippe Vaast +6 more
TL;DR: In this paper, the authors compared the impact of Inga densiflora on water use and drainage in a coffee agroforestry system (AFS) compared to coffee monoculture (MC) in Costa Rica.
Journal ArticleDOI
Leaf area index as an indicator of ecosystem services and management practices: An application for coffee agroforestry
Simon Taugourdeau,Guerric Le Maire,Jacques Avelino,Jeffrey R. Jones,Luis G. Ramirez,Manuel Jara Quesada,Fabien Charbonnier,Federico Gómez-Delgado,Jean-Michel Harmand,Bruno Rapidel,Philippe Vaast,Olivier Roupsard +11 more
TL;DR: In this paper, the relationship between the HR-LAI farm map and NDVI from the Moderate Resolution Imaging Spectroradiometer (MODIS) was calibrated with LAI 2000 and a new technique based on the cumulative distribution of LAI along transects.
Journal ArticleDOI
Coffee agroforestry systems in Central America: II. Development of a simple process-based model and preliminary results
TL;DR: In this article, the authors developed a simple dynamic model of coffee agroforestry systems, which includes the physiology of vegetative and reproductive growth of coffee plants, and its response to different growing conditions.
