Carbon in aerial biomass, agroforestry system of Theobroma cacao in Los Laureles Natural Laboratory, 2018

Abstract

The study was carried out in order to determine the carbon stored in aerial biomass of the agroforestry system (SAF) in Los Laureles Natural Laboratory of URACCAN in Hormiguero community, Siuna municipality, the (non-destructive) method was used by applying carbon percentage (50%) on dry biomass, suggested by Intergovernmental Panel on Climate Change, Winrock International, The United Nations - Program on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries. The study is quantitative, descriptive and cross-sectional.The agroforestry system is sequential, with an extension of 2.84 ha, in which a 100% inventory of forest and fruit trees was made; however, in the cocoa a sampling with an intensity of 8.45% was carried out, distributing 12 rectangular plots of 10 by 20 m, systematically distributed at a distance of 48.65 m between the plot. The System has an aerial biomass of 10.35 tons (t), distributed as follows: fruit trees, 0.44 t.; forest species, 4.70 t. and cocoa, 5.21 t. It is a quantitative, descriptive and transversal research.The agroforestry system as a carbon storage bank until the moment of data collection had 1.44 t carbon per hectare (C / ha) accumulated in aerial biomass of forest and fruit species; on the other hand, the cocoa component in its aerial biomass has 1.47 t C / ha, with a total of 2.91 t C / ha. The environmental economic value of carbon storage in Los Laureles Natural Laboratory is $ 53.36 per hectare.
