Effects of Erythrina poeppigiana pruning residues on soil organic matter in organic coffee plantations
(CATIE, Turrialba (Costa Rica) University of Wales, Bangor (RU). School of Agricultural and Forest Sciences, 2005)
The effects of Erythrina poeppigiana pruning residue effects on soil organic matter were investigated with three different objectives. Firstly, to study the effects of proximity of this shade tree on soil characteristics ...
Distribution of absorbing roots of coffee (Coffea arabica L.) and rubber (Hevea brasilensis Muell. Arg.) in mixed plantings in two ecological zones of Costa Rica
(IICA, Turrialba (Costa rica), 1962-08)
Se estudió la distribución de raíces absorbentes de árboles adultos de café y hule en cultivos intercalados en dos zonas ecológicas de Costa Rica. El método utilizado consistió en una modificación del método de trinchera ...
Distribution and foraging by the leaf-cutting ant, Atta cephalotes L., in coffee plantations with different types of management and landscape contexts, and alternatives to insecticides for its control
(CATIE, Turrialba (Costa Rica). Universidad de Idaho, ID (EUA), 2006)
Atta cephalotes L., the predominant leaf-cutting ant species found in coffee farMON in the Turrialba region of Costa Rica, is considered a pest of the crop because it removes coffee foliage. I applied agroecosystem and ...
The effects of local and landscape context on leafhopper (Hemiptera: cicadellinae) communities in coffeee agroforestry system of Costa Rica
(CATIE, Turrialba (Costa Rica)
University of Idaho, Moscow, ID (EUA), 2008-05)
This study examined the effects of local (shade composition, organic or conventional management, and weed management) and landscape (surrounding land uses) context on sharpshooter communities in coffee agroforestry systeMON ...
Characterization of the spatial variability of soil properties and coffee fine roots in shade tree-coffee associations under organic and conventional managment practices
(CATIE, Turrialba (Costa Rica), 2011)
Investigaciones en sistemas agroforestales han enfatizado que estudios sobre interacciones bajo el suelo son importantes para el entender el desarrollo y la distribución de raíces finas de cultivos y árboles asociados. ...
Carbon and economic performance of coffee agroforestry systems in Costa Rica and Nicaragua
(CATIE, Turrialba (Costa Rica). Bangor University (United Kingdom), 2012)
Coffee agroforestry systeMON (CAFS) sustain the livelihoods of many people globally at the same time as providing important ecosystem services such as carbon sequestration that help mitigate climate change. The carbon ...
