Incidencia de la Mesofauna en el almacenamiento de Carbono Orgánico Total en los suelos del páramo de la comunidad de Guangopud parroquia Juan de Velasco cantón Colta

Abstract

The mesofauna incidence in total wasteland soil organic carbon storage of Guangopud community, Juan de Velasco Parish, Colta Canton got determined. A double stratification sample design and of different variables measurement were applied. For the research areas three conglomerates with three plots of 3600m 2 each one resulting in 9 plots under permanent monitoring and distributed in the whole area. Three resear ch areas were determined: High, medium and low, 71% of soils are volcanic inceptisol and it has loamy sand texture with stony granular structure <5%. In de soil mesofauna it was possible to determine 10 mesofauna species belonging to diptera group, three t o Lumbricidae, two to Coleoptera and the remaining to Forticulidae, Collembola and Acaria. The carbon content variation is inversely proportional to depth getting a maximum value in plot 5 with 122 ton/ha, while the lowest content was found in plot 2 with 91,72 ton/ha , and a medium value of 102 ton/ha. The highest carbon concentration of edaphic mesofauna is foud in the first conglomerate with a maximum value of 23,7% and 60,10% in soil carbon. The lowest value was found in plot 7 with 12,4% for edaphic me sofauna and 49,5% for the soil. This proves that density of edaphic mesofauna in carbon storage is proportional to total carbon - accumulated content is proportional to mineral horizon depth. Drain density, texture and structure are essential factors for eda phic mesofauna growth, this provides a highest density to species and intervention level is evident due to low - anthropic areas suitable for edaphic mesofauna growth. From the results, it is important for the Guangopud community to make an ecosystem conserv ational plan for paramos in return of environmental service warranty.
