Cuantificación del servicio ecosistémico de almacenamiento de carbono en el suelo de los ecosistemas Bosque Siempre- Verde de Tierras Bajas, Bosque Siempre-Verde de Pie de Monte y Bosque Siempre-Verde Andino Montano Bajo de la provincia del Napo.

Abstract

Ecuador hosts one of the largest "laboratories" of life in its Amazon region. This occurs as result of many factors: climatological, orographic, geological, among others. For this reasons, Ecuadorian Amazon is an interesting place for scientific research. An essential component for the development of the biodiversity is the soil which change its characteristics by various factors. The research measured conditions of pH, conductivity, humidity, organic matter, total nitrogen, phosphorus, iron, interchangeable acidity, texture and its origin. It was analyzed 27 samples at different altitudes with 3 types of common "virgin" forests in the study area: Bosque Siempre-Verde de Tierras Bajas (BSVTB), Bosque Siempre-Verde de Pie de Monte (BSVPM) and Bosque Siempre-Verde Andino Montano Bajo (BSVAMB). Samples were taken in 3 types of depths: 0-10, 10-20, 20-30 cm. As results; it was obtained that carbon storage in Amazonian soils depends on altitude. The parameters: organic matter, humidity and iron also showed a directly proportional correlation to the altitude. However, measurements of: phosphorus, pH, conductivity and interchangeable acidity showed that there is no marked correlation between the concentration of these parameters vs altitude. It was also determined that the BSVTB doesn´t come from volcanic origin; while the soils coming from the forests: BSVPM and BSVAMB came from volcanic origin.
