Determinación de carbono orgánico total presente en el suelo y la biomasa de los páramos de las comunidades de chimborazo y shobol llinllin en Ecuador

Abstract

[ES] En la determinación del contenido de carbono orgánico total presente en el suelo y la biomasa (cobertura vegetal) de los páramos de las comunidades de Chimborazo, con 210ha de páramo cuya ubicación es 746667UTM-9825400UTM, y Shobol Llinllín, con 350 ha de páramo, 754680UTM–9854678UTM, pertenecientes a San Juan en Ecuador, se seleccionaron 9 puntos de muestreo de acuerdo a la variación, características y altitud del suelo, repartidos para este estudio en tres pisos altitudinales comprendidos, para el páramo de la comunidad Chimborazo, entre 3600-3900 msnm y, en el caso de Shobol Llinllín, entre 3600- 3950 msnm. Las muestras del suelo fueron tomadas a tres profundidades diferentes de 0-30 cm, 30-60 cm y 60-90 cm. En lo referente a las muestras de biomasa se extrajeron 4 tipos de muestras: paja, raíz de paja, almohadilla, y raíz de almohadilla, las cuales se analizaron mediante el método colorimétrico de WallKley-Black por la oxidación del dicromato de potasio. Con la diversidad de variables tomadas en cuenta, los datos obtenidos indican que existe mayor contenido de carbono orgánico total en los primeros estratos de suelo, en la paja y almohadilla; además, existe mayor porcentaje del mismo en los suelos cuya cobertura vegetal no ha sido intervenida, incrementándose con la altitud. Las comunidades de Chimborazo y Shobol Llinllín al poseer una significativa extensión de suelo de páramo, pueden ser utilizados como una alternativa para la captura y disminución de gases de efecto invernaderomanteniendo intacto el carbono orgánico presente en el suelo y en la biomasa.

[EN] In the determination of the content of the total organic carbon in soil and biomass of the moors of the communities of Chimborazo, with 210 ha of moors whose location is 746667UTM-9825400UTM, and Shobol Llinllín, with 350 ha of moors, 754680UTM- 9854678UTM, belonging to San Juan in Ecuador, 9 points of sampling were selected according to the variation, altitude and soil characteristics, divided for this study in three altitudinal thresholds, in the case of the moors of Chimborazo community among 3600 and 3900 MSL and among 3600 and 3950 MSL for Shobol Llinllín. Soil samples were taken at three different depths of 0-30 cm, 30-60 cm and 60-90 cm, and 4 types of samples of biomass were extracted: straw, root of straw, pad, and root of pad, they were all analyzed using the colorimetric method of WallKley-Black oxidation by potassium dichromate. With the diversity of variables taken into account, the obtained data indicate that there is more total organic carbon content in the first layers of soil, straw and pad.In addition, there is a greater percentage of organic carbon in the soils that have not been intervened and this increase with altitude. Chimborazo and Shobol Llinllín communities, possessing a significant extension of moor soils, can play a role in the capture and reduction of greenhouse gases while maintaining intact the organic carbon in soil and biomass
