Evaluación de concentración de carbono orgánico y servicios ambientales en zonas intervenidas y no intervenidas en cuatro localidades del cantón Cayambe, 2024

Abstract

The main objective of this research was to determine the SOC (soil organic carbon concentration) and environmental services in two intervened areas and one non-intervened area, through physical-chemical analysis, and the evaluation of the impact of anthropogenic activities on the percentage of SOC (soil organic carbon), in four locations in the community of Pesillo, Cayambe canton. This work was developed experimentally, with the drill and cylinder method, for which 24 samples were obtained, each composed of 15 homogenized subsamples, with the purpose of taking them to the laboratory for an analysis of physical-chemical parameters, such as; pH, electrical conductivity, bulk density, gravimetric humidity, porosity, organic matter, soil organic carbon and texture. It was determined that both the intervened soils and non-intervened soils have significantly similar statistical values, that is, that the uptake of organic carbon in the soil is not defined by the technique or activity carried out on it. However, it could be observed that the organic carbon concentration value of the unintervened area is lower compared to the concentration values of areas intervened by anthropogenic activities. Through population surveys, it was identified that 40.63% of the community believes that the importance of soil environmental services is moderate, and 71.88% of the population says that food and biomass generation, base of human activities, reserve biodiversity, water filtration and containment, are environmental services that the soil provides to its community.
