Almacenamiento de carbono en sistemas agroforestales en los Llanos Orientales de Colombia por Hernández Núñez, Héctor E., Andrade, Hernán J., Suárez Salazar, Juan C., Sánchez A., José R., Gutiérrez S., David R., Gutiérrez García, Gustavo A., Trujillo Trujillo, Edwin, Casanoves, Fernando

“…Methods: Forty-four sampling plots were established, where dasometric measurements were taken from individuals with a trunk diameter at breast height (dbh) ≥ 2.5 cm (saplings, trees and large trees), whose values were transformed to carbon with biomass models and a default carbon fraction. In the three agricultural systems, the number of cocoa and coffee trees and associated plants was counted, and the type of use (timber, food, combustion) was identified. …”
