Cuantificación del flujo de carbono en suelos de bofedales del área de conservación comunitaria cunuyacu en la reserva de producción de fauna chimborazo

Abstract

This research aimed to quantify the carbon flow in wetland soils of the Cunuyacu Community Conservation Area in the Chimborazo Fauna Production Reserve. Sampling was carried out in July and August, and the equation of finite populations was used to determine the sample size, obtaining 18 plots that represent six conglomerates; In each plot, 3 points were taken, having a total of 54 + sampling points throughout the study area. Sampling was carried out with a borehole; samples of 0-30 and 30-60 cm depth were extracted, to be later subjected to the calcination method in the laboratory to determine matter and organic carbon. Also, the monolith technique was applied to determine the carbon in the three study deposits (aerial biomass, necromass and underground biomass). Concerning the determination of edaphic respiration, a sample composed of 5 random points in each conglomerate was made, and later they were analyzed in the laboratory with the OxiTop system. Statistical analyzes were carried out using the Infostat software to establish the correlations during the respiration stages and the storage of total organic carbon. It is concluded that the soils of the wetlands store 128 g C and release 0.099 mg CO2/Kg of dry soil x h-1, which indicates that this study area acts as a significant carbon sink. It is recommended that monitoring be carried out in the rainy season to find out if there are variations in edaphic respiration and carbon content variations.
